About Parallels Virtual Automation

Parallels Virtual Automation is a flexible and easy-to-use administration tool for managing groups of physical servers running Parallels Virtuozzo Containers, Parallels Containers for Windows, Parallels Server Bare Metal, and Parallels Cloud Server. With Parallels Virtual Automation, you can manage both physical servers and virtual environments hosted on those using a supported Web browser.

Supported Web browsers:

• Internet Explorer 9.x, 10.x or 11.x,

• Firefox 26 or newer,

• Safari 5.x or newer,

• Chrome 31.x or newer.

Note: Other browsers should work as well, but only those listed above have been tested for compatibility with Parallels Virtual Automation 6.1.

After Parallels Virtual Automation has been installed, you can register available physical servers with it. As physical servers are registered with Parallels Virtual Automation, they form a group of physical servers or a group of Nodes (further in this Guide other terms may also be used: Node Group, Nodes registered in Parallels Virtual Automation, etc.). For the definitions, see Glossary (p. 301). As an administrator, you can manage both single physical servers and physical server groups. With a group of physical servers, you can perform a number of collective administration tasks, such as:

• creating a logical structure of physical servers and the virtual environments residing on them;

• migrating virtual environments between physical servers;

Introduction

• copying OS and application templates from one physical server to another;

• making virtual environment template stored on a VM Templates Storage (p. 163) available to

other registered physical servers;

• consolidating physical server IP addresses into a network address range.

Parallels Virtual Automation user accounts are managed by the administrator. An administrator can add and remove users, and set user access privileges. The access privileges determine what operations a user can or cannot perform on registered virtual environments.

To use the Parallels Virtual Automation for administering a physical server and the virtual environments residing on it, you need to install Parallels Containers for Windows on the required physical server. To learn on what operating systems Parallels Virtual Automation can be installed, refer to the Parallels Virtual Automation installation guide. The Virtuozzo Containers software can be installed on Windows 2003 Server and Linux (Red Hat Enterprise Linux 4, Fedora Core 7, etc.) operating systems. Most of the Parallels Virtual Automation working principles are the same, or similar, for both operating systems.

With Parallels Virtual Automation, you can perform the following actions:

• Customize the interface of Parallels Virtual Automation and define personal settings (p. 22)

• View and install licenses (p. 166)

• View physical server resource consumption (p. 45)

• Migrate a physical server to a Container (p. 98)

• Create new Containers and virtual machines (p. 120)

• Edit Container configuration (p. 107) and virtual machine configuration (p. 131), network

parameters, (p. 229) and other settings

• Manage Virtual Environment backups

• Clone a Container (p. 94) or a virtual machine (p. 143)

• Manage Container templates (p. 111) and virtual machine templates (p. 145)

• Manage and monitor virtual environment resources (p. 45)

• View logs and monitor virtual environment operations

• Manage Container group and perform virtual machine group actions

• Change a virtual environment's status (p. 56)

• Reinstall and/or repair a Container

• etc.

Logging In

The Parallels Virtual Automation administrator logs into Parallels Virtual Automation from a browser by using the IP address (or hostname) of the corresponding physical server and the TCP port (4648 by default). If the physical server you wish to manage is a Slave Server (p. 301), you should log in to the Master Server (p. 301) of this Group. Logging in by the IP address/hostname to a Slave physical server is not allowed. When connecting to the physical server, you should enter the OS

administrative credentials ( Login button.

The Parallels Virtual Automation administrator can endow other users with a certain scope of rights and privileges in Parallels Virtual Automation (see Managing Parallels Virtual Automation Security). These users can be created as Parallels Server or Parallels Containers internal users or taken from an external LDAP-compliant database. They log into Parallels Virtual Automation by the same IP address/hostname and port as the physical server administrator by using their respective user names and passwords. The set of actions these users will be able to perform in Parallels Virtual Automation will be defined by their privileges.

Whatever way you use, once you have connected to the virtual environment, you are recommended to provide a valid email address on the Editing User's Personal Settings page (p. 22) in order to be able to log into Parallels Virtual Automation in case you forgot your password. The Forgot your password? link on the login page allows you to enter your user name and the email address provided on the Parallels Virtual Automation configuration page in order to receive an URL at this address informing you how to change your password.

Parallels Virtual Automation Interface Overview

The Parallels Virtual Automation interface has been designed to let the Parallels Virtuozzo Containers or Parallels Server administrator quickly perform all possible tasks through an intuitive navigation system.

The main components the Parallels Virtual Automation interface consists of are:

• The left menu frame lists all your physical servers and virtual environments. You can access

main operations to be performed on them by right-clicking the server or virtual environment;

• The toolbar on top of the right frame allows performing most frequent actions on your physical

servers and virtual environments. When necessary, the toolbar includes a few more buttons for performing additional actions;

• The content part on the right frame displays the content of the chosen object: a physical server,

a virtual environment or any management unit.

• The My Tasks pane at the bottom of the right frame allows viewing all operations of the current

user that run at the moment or have been finished. The pane is minimized by default.

The actual left menu appearance can be changed by clicking any of the following buttons located at the bottom:

• Infrastructure - displays physical servers and virtual environments only. Other sections are

folded.

• Logical View - looks the same way as the Infrastructure menu, the only difference that the

virtual environments can be distributed between all folders or physical servers no matter what physical servers they physically belong to. Other sections are folded.

Getting Started With Parallels Virtual Automation

• Resource Library - displays the resource library sub-sections only: Software, Templates, IP

Pools, and Virtual Networks. Other sections are folded.

• Management - shows the Management sub-sections only: Workflow, Updates, Scheduler,

Alerts & Events, Tasks, and Support. Other sections are folded.

• Setup - displays the Setup sub-sections only: Network, Backups, Licensing, Security, and

Virtual Environment templates. Other sections are folded.

• Full view - makes the left menu display all the above as a tree.

Here and after, we use the full view of the left menu for description.

The upper most element on the menu is the Infrastructure link. If expanded, it displays your hierarchical structure of physical servers and virtual environments hosted on them as lower levels. Each of the physical servers and virtual environments that make up your Parallels Virtual Automation infrastructure displays its name on the Infrastructure-oriented left menu, which, if clicked, leads to its dashboard.

The content of the right frame always depends on what option you have clicked on the left menu frame. If you have clicked a physical server, the right frame will show the physical server relating information and operations, for a virtual environment the right frame will display the virtual environment relating sections and operations, and so on. See the Using Context-menu section (p.

20).

Extending Standard Browser Functionality

Parallels Virtual Automation extends the basic functionality of standard web browsers by providing you with the following facilities:

• support for the drag-and-drop operation within certain Parallels Virtual Automation

components;

• support for the use of the Parallels Virtual Automation context menu with certain Parallels Virtual

Automation objects.

Using Drag-And-Drop

Parallels Virtual Automation allows you to drag-and-drop elements in the left menu frame by selecting them with a mouse and moving them to another place in this frame. The list of main operations for which Parallels Virtual Automation provides the drag-and-drop support is given below:

• Moving any physical servers under the Infrastructure view to any folders available under this

view or within the Logical View item;

• Moving any virtual environments listed under the corresponding physical servers in the

Infrastructure view to any folders available under this view or under the Logical View item;

Getting Started With Parallels Virtual Automation

• Moving physical servers and virtual environments between folders under the Infrastructure

view;

• Moving a folder under the Infrastructure view to another folder within this view;

• Moving physical servers and virtual environments between folders under the Logical View

mode;

• Moving a folder under the Logical View mode to another folder within this view;

To perform a drag-and-drop operation, do the following:

1 Place the cursor over the object (e.g. a virtual environment) you wish to drag-and-drop and

press the mouse button.

2 Hold down the mouse button and drag the object (e.g. to some folder under the Logical View

item).

3 Release the mouse button to drop the object.

Upon the successful operation, the object will be shown in the place where it was dropped.

Using Context Menu

Parallels Virtual Automation supports quick access to the main features through the contextmenus. You can use context-menus to manage physical servers and virtual environments. Below are some common uses for the context menus in Parallels Virtual Automation:

• Right-click the Infrastructure view to create a new virtual environment on any of your physical

servers, create a new folder under the Infrastructure view, or configure the security policy for all the physical servers currently registered in Parallels Virtual Automation.

• Right-click a physical server to perform the most common operations on your physical servers:

create a new virtual environment, install a new OS or application template, reboot the physical server, configure the security policy for the physical server, etc. The same menu is also available if you right-click a physical server on the Hardware Nodes tab of the Infrastructure window.

• Right-click virtual environment to perform such operations as starting, stopping, or restarting

the virtual environment, creating virtual environment clones, migrating the virtual environment to another physical server, etc. The same menu is also available if you right-click a virtual environment on the Virtual Environments tab of the Infrastructure window.

• Right-click the Logical View to create a new folder, physical server, or virtual environment

under this item and to configure the security policy for all the physical servers currently registered in Parallels Virtual Automation.

If you work with Parallels Virtual Automation via the Mozilla Firefox browser, you may encounter the following problem: after right-clicking any of the aforementioned items, you will see the Parallels Virtual Automation and the browser context menus displayed. To display only the Parallels Virtual Automation context menu, perform the following operations:

1 In the Mozilla Firefox browser, open a new tab, type about:config in the address field, and

press the Enter key.

automatically on the left Parallels Virtual Automation menu, the virtual environment

dashboard screen and the Tasks pane without refreshing the current page manually. If you have problems with the connection to the Master Server (e.g. the bandwidth is low or the connection is unstable), enabling this function might make your work in Parallels Virtual Automation inconvenient and slow. In this case it is better to clear the check box.

After you decide on the suitable configuration and click the Submit button, the settings will be remembered for the current browser and user only. If you change the browser or the current user within the same browser, the default settings will be used until you perform a new customization.

Defining Personal Settings

On the Personal Settings tab of the User Profile screen, you can configure some personal data.

You can access the User Profile section by clicking the login name in the upper part of the screen.

As a Parallels Virtual Automation user, on this page you can revise, change or add the following personal data:

• The Login field is for information purposes only, you cannot change it.

• To change your password, enter the current password to the Old Password field, and a new

password into the Password and Retype the password fields. Please make sure it is difficult enough to pick up, so using birthdays and relatives' names for a password is not probably the best approach to ensuring your security.

Follow the PVA requirements to set up a reliable and secure password:

• Passwords must be at least six characters long.

• Passwords must contain elements from three of the four following types of characters:

• English uppercase letters (A, B, C, ... Z);

• English lowercase letters (a, b, c, ... z);

• Westernized Arabic numerals (0, 1, 2, ... 9);

• Non-alphanumeric characters (special characters) ($,!,%,^).

If your user information is taken from an external authentication database registered in Parallels Virtual Automation, you cannot change your password as it is taken from this database.

• The Full Name and Description fields are editable only if your user information is stored in the

regular Parallels database. If you are a user of the host OS (including root/Administrator) or of an external authentication database having access to Parallels Virtual Automation, you cannot change your full name as it is taken from the corresponding database.

• The Email field should be filled in with a correct email address to enable the functionality of

restoring your password, if you forgot it. If your user information is taken from an external authentication database registered in Parallels Virtual Automation, you cannot edit your email address as it is taken from this database.

To submit the changes, click Submit, otherwise click Cancel.

Getting Started With Parallels Virtual Automation

Organizing Logical Structure

Parallels Virtual Automation allows you to organize all your registered physical servers and with virtual environments on them in the following ways:

• All of them present a logical and easily manageable structure (with as many levels as you like).

• The other Parallels objects, like OS, and application templates, and Container backups, are

automatically filtered to conform to the current level of the object hierarchy.

• The Parallels Virtual Automation security policies can be set up not on the physical server or

virtual environment level, but on the level of an arbitrary group of objects, provided these objects are united into a folder.

There are two independent ways to design the structure organization. They are called Infrastructure and Logical View and presented as top-level elements in the Parallels Virtual Automation left menu. You can use either one of them or, better, both at once, as their functions are different:

The Infrastructure view allows you to display the physical organization of the PVA infrastructure. For example, all the physical servers will take place one level lower than the datacenter, and all the virtual environments running on a certain physical server will be shown under it. You can create your own folders in the Infrastructure group, but you cannot violate the order of nesting objects. As a way to help with the visual representation of physical objects, the folders you create here can also be called Datacenters and Racks.

Logical View allows you to group your physical servers and virtual environments in your own way independently of the physical infrastructure. For example, by grouping all the financial department activities under a common ‘FinDep’ folder, your organization will be able to manage them as a single entity by collectively managing permissions, scheduling backups, applying system updates, and more. Additionally, physical server or virtual environment may simultaneously appear in any number of folders.

The main operations related to organizing the PVA infrastructure are available with the top toolbar buttons visible if you are currently located in the Infrastructure/Logical View context (i.e. not in the physical server or virtual environment context). Below are the ways to set about:

• Adding a folder. On the left Parallels Virtual Automation menu, click the folder in which you want

to create a new folder. Then, if you are in the Infrastructure context, click the Add New Subfolder button on the top toolbar. In the Logical View context, click the Add to Folder button on the top toolbar, then click New Subfolder.

• Renaming a folder. On the left Parallels Virtual Automation menu, click the folder you wish to

rename. On the top toolbar, click the Manage Folder button, then click Configure.

• Moving a folder. On the left Parallels Virtual Automation menu, click the folder you wish to

move. On the top toolbar, click the Manage Folder button, then click Move.

• Deleting a folder. On the left Parallels Virtual Automation menu, click the folder you wish to

delete. On the top toolbar, click the Manage Folder button, then click Delete.

Getting Started With Parallels Virtual Automation

• Including a physical server in a folder. Click on Infrastructure on the left Parallels Virtual

Automation menu and go to the Hardware Nodes tab. Select the physical server(s) you wish to include in a certain folder and click Move on top of the Hardware Nodes table. If you are working with Logical View, the course of actions is a bit different, because any physical server can belong to any number of folders. On the left Parallels Virtual Automation menu, click the folder where you wish to include the physical server. Then click the Add to Folder button on the top toolbar, and select Hardware Node.

• Including a virtual environment in a folder. In the Infrastructure view, the virtual environments

always go with the physical server on which they are hosted, so you cannot include them separately in folders. In Logical View, any virtual environment can belong to any number of folders. On the left Parallels Virtual Automation menu, click the folder where you wish to include the virtual environment. Then click the Add to Folder button on the top toolbar, and select Container.

• Moving a physical server or a virtual environment to another folder. These actions do not

essentially differ from including these objects in folders, so you should be guided by the explanations given above.

• Removing a physical server or a virtual environment from the Infrastructure view. Unregister

the corresponding physical server (the Unregister button on The Hardware Nodes tab) or delete the virtual environment (the Delete button on the Containers tab).

• Removing a physical server or a virtual environment from a Logical View folder. On the left

Parallels Virtual Automation menu, click the folder from which you wish to delete a physical server/virtual environment, then go to the Hardware Nodes/Containers tab. Select the object(s) you want to remove and click Remove on top of the table.

Using the built-in Parallels Virtual Automation functionality, you can create a logical structure of your own:

• create new folders (p. 24) and edit them (p. 25);

• change the structure hierarchy by mowing folders (p. 25) and physical servers (p. 25);

• change the hierarchy by adding physical server (p. 26) and virtual environment (p. 26) to folders,

i.e. you can group the physical and virtual environments according to your needs.

Adding New Folder

The new folder you are creating will be placed directly under the currently selected folder in the

Infrastructure or Logical View hierarchies (p. 27).

Folders created are assigned a Folder Type. The default folder type is Folder. Folders created in the Infrastructure hierarchy can be of type Folder, Datacenter, or Rack. Folders created in the Logical View hierarchy can be of type Folder or Datacenter.

The Folder Title field is mandatory, as it sets the name of the folder. Duplicate folder names are not allowed.

Getting Started With Parallels Virtual Automation

For detailed information on working with Infrastructure of Parallels Virtual Automation and Logical View trees, refer to Organizing Management Infrastructure.

Editing Folder Properties

On the Configure screen, it is possible to change the name of a folder and the icon representing the folder type.

To change the name of the folder, enter a new folder name in the text box in the Title section. To change the folder icon, select the radio button next to the desired icon in the Folder Type section. Click the Submit button to apply any changes, otherwise click Cancel.

Any changes made to the folder name or folder type will not affect any physical server or virtual environment settings.

For detailed information on working with Infrastructure of Parallels Virtual Automation and Logical View trees, refer to Organizing Management Infrastructure.

Moving Folder

Folders under the Infrastructure and Logical View level can be moved to other locations within their corresponding hierarchies. You cannot change the location of the following folders:

• the parent folder - a folder is already a child of its parent;

• the current folder - a folder cannot be a child of itself;

• any child folder - this would break the hierarchical structure by disconnecting any links to the

hierarchy (one or more folders directly under the folder being moved would have to become the root physical server(s) in a new detached folder hierarchy).

In the drop-down within the Destination Folder section, select the folder you want to move the currently selected folder to. Invalid destinations cannot be selected and are grayed out. Click the Move button to commit the folder move operation, or Cancel to discard it.

For detailed information on working with Infrastructure of Parallels Virtual Automation and Logical View trees, refer to Organizing Management Infrastructure.

Moving Physical Servers to Another Folder

Physical servers can be moved from folder to folder in the Infrastructure view only, because the Logical View mode allows one and the same object to be simultaneously included in different

folders, so this mode deals with objects inclusion, and not their moving.

For the selected physical server(s) to be included in the folder of your choice, select this folder from the Destination Folder drop-down menu and click Submit. The physical server(s) will be displayed on the Parallels Virtual Automation left menu as sub-levels of the selected folder.

Getting Started With Parallels Virtual Automation

For detailed information on working with Infrastructure of Parallels Virtual Automation and Logical View trees, refer to Organizing Management Infrastructure.

Adding Physical Servers to Folders

On the Add Hardware Node(s) screen you can include any registered physical server in the current folder of the Logical View hierarchy. To do that, press the Add button below the Hardware Nodes section, select the physical servers to belong in the folder, click Use Selected, and finally click Save.

For detailed information on working with Infrastructure of Parallels Virtual Automation and Logical View trees, refer to Organizing Management Infrastructure.

Adding Virtual Environments to Folder

On the Add Virtual Environment(s) screen you can include any of the existing virtual environments in the current folder of the Logical View hierarchy. To do that, press the Add Virtual Environments button below the Virtual Environments section, select the virtual environments to belong to the folder, click Use Selected, and finally click Save.

Viewing Physical Servers Information

Hardware Nodes is a common term for physical servers running Parallels Virtuozzo Containers, Parallels Server Bare Metal or Parallels Cloud Server. Physical servers can be of the following types:

• a Windows computer with Parallels Virtuozzo Containers for Windows;

• a Linux computer with Parallels Virtuozzo Containers for Linux;

• a bare metal computer with Parallels Server Bare Metal or Parallels Cloud Server;

• a Mac computer with Parallels Server for Mac.

The Parallels Virtual Automation functionality enables you to register, group under logical units, and manage a number of such servers.

If you deal with a large number of registered physical servers (and virtual environments), it can be convenient to organize them into multiple logical units divided by architecture, virtual environment type or other principles. For details on how to do this, consult Organizing Logical Structure (p.

23).

You can also set up a convenient and automated structure of IP pools. The IP addresses within these pools can be automatically assigned to the certain groups of virtual environments, thus eliminating possible IP conflicts between virtual environments and physical servers. Doing this will also let you save time on manual IP assignment. For details, see Managing IP Pools (p. 238).

To distribute workload, you can migrate virtual environments between physical servers registered in the Parallels Virtual Automation infrastructure.

Linux-based Containers can be migrated to Parallels Server Bare Metal physical servers or to Linux-based physical servers with Parallels Virtuozzo Containers installed. Windows-based Containers can be migrated between Windows-based physical servers. Virtual machines can be migrated between Parallels Server Bare Metal and Mac OS physical servers.

On the Hardware Nodes screen, you can review the list of physical servers currently registered in Parallels Virtual Automation and see the physical server details shown as the following table:

Green The physical server (or virtual environment) consumes less than 90% of the CPU time allowed to it. This

means that you can run more applications inside the physical server (or virtual environment) without violating the performance of the current ones. If the physical server consumes more than 90% of the allowed CPU time, but for an insignificant time, the color remains green as this situation is not dangerous.

Yellow The physical server (or virtual environme

is up to you to decide whether this situation suits you, but you should bear in mind that additional applications launched inside the physical server might experience shortage of available CPU power. You may need to consider the possibility of cutting down the number of processes.

Organizing Parallels Virtual Automation Infrastructure

Red The physical server (or virtual environment) consumes 100% of the CPU power allowed to it, i.e. all the

available CPU power, for a long time. Usually this means that currently there is some CPU-intensive process inside the physical server caused by a temporary task. For example, this may happen if you are compiling a package in the physical server (or virtual environment) or in similar cases. In this case you should simply wait for this task to complete.

However, if you do not know the reason for the CPU overconsumption, turn to the Parallels Virtual Automation System processes page to determine which processes are causing the problem and take the corresponding measures. For example, you might want to terminate or kill the offending process. Otherwise, the system performance may continue low for a long while.

For disk-related parameters the meaning of the three zones is the following:

Zone Description

Green The physical server (or virtual environment) consumes less than 90% of disk resources allowed to it. This

means that the physical server has currently no problem with disk resources.

Yellow The physical server (or virtual environment) is using between 90% and 100% of the disk resources available

to it on the physical server. The situation is rather dangerous since the next disk resource allocation request can be refused by the physical server (or virtual environment). Therefore, you should erase unnecessary data from the physical server immediately. On a Linux physical server, a physical server (or virtual environment) is allowed to consume more than 100% of its disk quota only during the grace period (see the quotatime parameter in the resources consumption details). If you do not solve the problem during this time, the physical server will be denied some of the disk resources and you might lose valuable data.

Red The physical server (or virtual environment) has exceeded the soft limit and a disk resource allocation has

been refused by it. This might have resulted in a loss of some valuable data or other problems inside the physical server. To discontinue this very serious situation, you should erase unnecessary data from the physical server immediately.

For memory-related parameters the meaning of the three zones is the following:

Zone Description

Green The physical server (or virtual environment) consumes less than 90% of the memory-related resource

allowed to it.

Yellow The physical server (or virtual environment) consumes between 90% and 100% of the memory-related

resource allowed to it. It is up to you to decide whether this situation suits you, but you should bear in mind that additional applications launched inside the physical server might experience shortage of the corresponding resource. Judging by the offending resource, you might determine the reason for its shortage and take the corresponding measures.

Red The physical server (or virtual environment) has been denied this memory-related resource due to its

overusage. This might have resulted in application crashes or other problems inside the physical server (or virtual environment).

Viewing Infrastructure Event Logs

The Events subtab keeps track of all the changes in the statuses of all the virtual environments registered on Parallels Virtual Automation physical servers. These changes may happen due to the virtual environment routine management via Parallels Virtual Automation, Parallels Management Console, command line operations, or due to the operation of some programs.

Organizing Parallels Virtual Automation Infrastructure

The Status Changes table on the Events subtab displays the information on the physical server and virtual environment changes as follows:

Column Name Description

Time The time when the status of a physical server or virtual environment was changed.

Object The name of a physical server or virtual environment whose status was changed.

Old Status The previous status of a physical server or virtual environment.

The description of all possible physical server and virtual environment statuses is provided in the Physical Server, Container and Virtual Machine Statuses section.

Status Obtained The current status of a physical server or virtual environment.

The description of all possible physical server and virtual environment statuses is provided in the Physical Server, Container and Virtual Machine Statuses section.

By default, the table shows 20 records, but you may have more records displayed by clicking the appropriate link above the table.

You may also have the Status Changes table display only those log records that have a particular date and time. On top of the table, click the Show Search link to display the fields where you can specify the boundaries of the time interval for which you wish to view the log; then click the Search link.

Backing Up and Restoring the Master Server

In the Parallels Virtual Automation 6.1 infrastructure, Master Server is a uniting element that ensures successful communication between all Slave physical servers in the system and their virtual environments. It also serves as a storage for management, security and other sorts of data. Just as you make a backup of any physical server or virtual environment in Parallels Virtual Automation, you can back up the Master Server and store this backup for the case of emergency.

You can learn how to download the backup script from the Parallels Knowledgebase

http://kb.parallels.com/en/6830.

Backing Up Physical Server

The PVA backup script pvabackup.vbs, after default download, is stored in the C:\Program Files\Parallels\Parallels Virtual Automation\Management

Server\bin\location. To back up a Master Server with the help of the PVA script, start it with the

following parameters:

cscript.exe pvabackup.vbs BACKUP c:\mn_backups

Managing Physical Servers

Where "c:\mn_backups" is an automatically generated location for the target backup. The backup name consists of the year, month, day, hour, minute, and second when the backup was made, for example "20091027222544". To give a backup a specific name, use the script with a concrete backup name:

cscript.exe pvabackup.vbs BACKUP c:\mn_backups b1

Where "b1" stands for the concrete backup name, and the storage location will be c:\mn_backups b1.

Restoring Physical Server

To restore the Master Server, the script should look as follows:

cscript.exe pvabackup.vbs RESTORE c:\mn_backups 20091027222544

Where 20091027222544 is the name of the target backup you want to restore from.

Note: The Master Server will be restored with all the values overwritten from the backup. The changes in the Master Server made after the date of this backup will be lost after the server has been restored.

Registering Physical Server in Parallels Virtual Automation

The following physical servers can be registered in the PVA infrastructure system:

• a Windows computer with Parallels Virtuozzo Containers for Windows or Parallels Containers

for Windows installed;

• a Linux computer with Parallels Virtuozzo Containers for Linux software installed;

• a bare metal computer with Parallels Server Bare Metal or Parallels Cloud Server installed;

To register a hardware node in Parallels Virtual Automation, the following firewall ports should be opened:

• PVA Slave physical server: 4433, 4434, 4435;

• PVA Management server: 4533, 4534;

Important: For the proper functioning of the registered server, you may need to open more ports. To learn information on other ports, refer to the KB article.

The newly registered physical server will be displayed in the physical server list on the Hardware Nodes screen (p. 29) and accessible via Parallels Virtual Automation for all the usual managing and monitoring PVA operations. Besides, physical servers registered in Parallels Virtual Automation form a joint physical servers pool which provides with the following collective actions:

• creating a logical structure of physical servers and the virtual environments residing on them;

Managing Physical Servers

• migrating virtual environments between physical servers;

• copying OS and application templates from one physical server to another;

• making virtual environment templates stored on a Virtual Manager Server available to other

registered physical servers;

• reserving pools of IP addresses and organizing IP ranges inside them;

Registering a new physical server to be managed through Parallels Virtual Automation is a simple action and all it takes is entering the following information on the new Node:

• The valid IP address of the physical server that will be used by Parallels Virtual Automation to

connect to this physical server. The physical server's IP address can be either of version 4 or of version 6. Enter this IP address to the Node Address field in the Connection to Hardware Node section. Note, that once you have added the hardware node under its current hostname, you cannot change it. If you want to change the hostname of a registered physical server, you should first unregister it from Parallels Virtual Automation. After you have edited the hostname, you can re-register it in the PVA system again.

• In the Administrative Login to Hardware Node section, you need to indicate the login name

and the password which are used to connect to the physical server as the administrator. Write the login name in the User Name field and the password in the Password field.

Selecting the Force registration even if Node is already registered in another Server Group checkbox is the option to choose when the physical server you are registering has already been and is still registered on another physical server and you need this physical server to be registered from your physical server. If you forcibly register the physical server, this physical server will be removed from the cluster it currently belongs to.

Clicking the Register button initiates the registering procedure.

When the registration procedure is over, the physical server is added to the list of registered servers. You can view the list by clicking the Infrastructure in the left menu and switching to the Hardware Nodes tab.

Managing Disk Images

If you have any file shares registered in Parallels Virtual Automation, the CD/DVD disk images available on these shares will be displayed on the CD/DVD Images tab of the Software screen.

The information, such as the name, size, status of all the disk images, presented in the Disk Images table is displayed according to the settings made on the Select Columns drop-down menu. If all the columns are selected, this table presents the following:

Column Name Description

Name The name of the disk image.

Description The description of the disk image.

Managing Physical Servers

Full Path The full path to the place where the disk image is stored.

Share The name of the file share hosting the corresponding disk image.

Size The size of the corresponding disk image.

Enabled A green tick opposite a disk image indicates that this disk image is enabled and can be

used, a grey circle means that the disk image is disabled and cannot be used.

Status The current status of the disk image.

To facilitate working with CD/DVD disk images available on the file shares registered in Parallels Virtual Automation, you may have the Disk Images table display only those disk images that conform to particular parameters. Above the table, click the Show Search link to display the fields where you can specify the parameters the disk images should meet; you can also customize these fields by clicking Customize. Then click on the Search link. To view all the CD/DVD disk images available on the file shares registered in Parallels Virtual Automation, click on the Reset Results link to the right of the parameter fields.

To manage several disk images at once, make use of the Parallels Virtual Automation toolbar right above the table. You are able to execute the following operations on disk images groups:

• Enabling any number of disk images (the Enable button).

• Disabling any number of disk images (the Disable button). You may need to disable a disk

image because of the following reasons:

• the CD/DVD disk image has become corrupted

• you want other users not to use the CD/DVD disk image.

To perform anything of the above, select the check boxes opposite the corresponding disk images and press the appropriate link on the Parallels Virtual Automation toolbar.

Clicking the disk image name in the Name column will lead you to the Configure Disk Image screen described in the following subsection.

Configuring Disk Image Parameters

The Configure Disk Image screen allows you to do the following:

• In the General Settings group, you can:

• Review the disk image name, the network path to the place where the disk image is stored,

and the disk image size.

• Add some description to the disk image or modify the existing one.

• Specify whether the disk image is enabled or not by selecting or deselecting the Enabled

check box.

• In the File Share Information group, you can:

• Review the name of the file share storing the disk image and the network path to the share.

Click the Save button to save the changes, otherwise, click Cancel. 40

Managing Physical Servers

Rebooting Physical Server

You may want to reboot your physical server. For example, this may happen if you have installed a new Linux kernel on the physical server and wish to start using it.

Before rebooting the physical server, keep in mind that usually this process takes 3-5 minutes. During this time, the physical server and all virtual environments residing on it will be unavailable. To reboot the physical server, click the Reboot Node button on the Physical server dashboard pane.

Note: When a physical server is accidentally powered off, the PVA system generates an alert message and notifies that the physical server resources are not available. The alert is generated after 10-15 minutes after the physical server failure.

Physical Server Dashboard Overview

The Physical Server Summary page provides an overview of the configuration and the current status of the given physical server and enables you to quickly launch the most typical server management tasks.

Depending on the physical server virtualization technology, the set of the commands and the configuration information differ. However, the tables below provide you with the joined description. A command or information, being specific for a concrete product, has the corresponding notice.

To change the settings, you can use the following subsections:

VM Default Settings

In this section, you can specify the following:

• VM Folder. The folder where newly created virtual machines will be stored by default. When

you change the location, the virtual machines that were earlier placed to a different location won't be moved to the new one. If you want to have them in a new location, you should manually move them.

• VM Backup Folder. The folder where virtual machine backups will be stored by default.

To specify the location, you can either type it in the field or use the Select button.

Parallels Service Settings

In this subsection, you can specify the memory limit that will be true to every virtual machine stored on this Parallels Server.

• Auto. The memory will be automatically allocated to a virtual machine depending on its needs.

• Manually. Specify the amount of the memory that any virtual machine will use. Irrespective of

the virtual machine needs, it won't be able to exceed the memory limit.

Managing Physical Servers

VM Remote Console Service Settings

With the help of these settings, you can establish a remote control of the virtual machine using the VNC protocol.

• In the Default Service Address field, specify the IP address for the VNC protocol to connect to

the virtual machine. You may need to do it if the Server has several IP addresses, out of which you need only one for connection.

• In the Service Base Port field, specify the base port starting from which the running virtual

machines will be assigned with port numbers.

When finished, click Submit to save the changes.

Managing Templates on a Physical Server

Managing Virtual Environments

Virtual environment is a generic term for Containers and virtual machines. A virtual environment is created on the basis of a virtualization technology and can be managed via Parallels Virtual Automation. Physical servers running Parallels Virtuozzo Containers or Parallels Containers for Windows can host Containers while physical servers running Parallels Cloud Server or Parallels Server Bare Metal can host both Containers and virtual machines.

You can find the list of all virtual environments hosted on servers registered in Parallels Virtual Automation on the Infrastructure > Virtual Environments screen (see Viewing Virtual Environments Information (p. 31)). On this screen, you can either right-click a virtual environment and select an operation from the context menu or select multiple virtual environments and click an operation button on the toolbar above the list. Available operations include:

• Create one or more virtual environments (New Virtual Environment):

• Start/restart/stop the selected virtual environments (Start/Restart/Stop).

• Pause the selected virtual environments (Pause). Pausing frees up the host CPU resources

while the consumption of other resources remains the same.

Stop the selected virtual environments without executing shutdown scripts (Power Off). This

•

operation is only available to users with administrative privileges in Parallels Virtual Automation. It can be used, for example, if a virtual environment has become broken and cannot be shut down properly.

• Suspend the selected virtual machines or Linux-based Containers (Suspend). This operation is

similar to putting a regular computer to sleep. The current virtual environment state (including the state of all running applications and processes) is saved to a special file on the host. After returning from the suspended mode, the virtual environment resumes operation from the same state it has been in before suspension.

• Back up the selected virtual environments (Back Up).

• Migrate the selected virtual environments a physical server registered in Parallels Virtual

Automation (Migrate).

• Clone the selected virtual environments (Clone).

• Delete the selected virtual environments (Delete).

• Configure the general settings of the selected virtual environments (Configure).

• Convert the selected virtual machines to templates (Convert to template).

• Clone the selected virtual environments to templates (Clone to template).

1. You can perform operations on multiple virtual environments only if they are based on the same virtualization technology.

2. You can also perform operations on a single virtual environment from its summary screen accessible by clicking that virtual environment's name.

The sections of this chapter describe operations on multiple virtual environments in more detail. For operations specific to Containers or virtual machines, see Managing Containers (p. 59) and Managing Virtual Machines (p. 119), respectively.

Starting to Create Virtual Environments

First of all, you should decide on the virtual environment type. You can create either a Container, or a virtual machine.

If you need to have virtual environments with guest OS different from the hosting physical server OS, create and use virtual machines. Using Parallels Server virtual machines, you can have a wide range of guest OSs installed in them. At the same time, you can create Parallels Containers. Their operating system should always coincide with the operating system of the hosting server. But they are less resource consuming than virtual machines.

Hardware Node Selection

Select the physical server where the created virtual environment is to reside. You can choose one of the following options:

• Select Hardware Node Automatically. Check this option to let the wizard automatically

choose a physical server from the list of servers registered in PVA Control Center. If you are going to make a Container, you should additionally indicate the server platform in the Specify a Platform list.

Managing Virtual Environments

• Select Hardware Node Manually. Check this option if you wish to select the physical server

yourself. In this case, you will be able to select the desired physical server in the Select Node list.

Virtual Environment Configuration

Specify the number of virtual environments you wish to create. By default, only one virtual environment is created. You can additionally select the template to be used as the basis for the virtual environment creation in the Virtual Environment Template (p. 165) list. If you create a virtual environment on the basis of a template, a new MAC address, different from the template's MAC, will be generated.

To proceed with the virtual environment creation, click Next. Your further steps will differ depending on whether you are creating a Container (p. 63) or virtual machine (p. 120).

Starting, Stopping, Pausing and Restarting Virtual Environments

A virtual environment may be started up, restarted, paused, and shut down like an ordinary computer. Depending on the virtual environment state, only those operations are accessible that comply with its current state. For example, a running virtual environment cannot be started for obvious reasons, and so on. The following virtual environment states can be characterized as stable:

Status Description

Running The virtual environment is running; therefore, it may only be restarted or stopped.

Down The virtual environment is stopped; therefore, it may only be started.

Repairing

The virtual environment is being repaired. You cannot perform any action on the virtual environment until you click the Finish Repair button on the Start Container in Repair Mode page (p. 104).

The current status of the virtual environment is available in the Status table of the virtual environment dashboard. The history of the status changes can be viewed from the Logs -> Tasks page of the virtual environment.

Note: Some operations are available either for virtual machines or Containers. For example, only virtual machines can be paused.

Besides these states, during virtual environment operations a virtual environment may be in one of the transitional states: mounting, starting, stopping, etc. When in a transitional state, you cannot perform any action on the virtual environment until the operation is finished. For descriptions of all possible virtual environment statuses, see Physical Server, Container and Virtual Machine Statuses.

Click the Start Virtual Environment, Stop Virtual Environment, or Restart Virtual Environment button to perform the corresponding action. On clicking one of these buttons, this action is logged.

Managing Virtual Environments

If you are managing a virtual environment residing on the physical server with the Linux operating system installed and wish to stop your virtual environment, bear in mind that there is a two-minute timeout for the virtual environment shutdown scripts to be executed. If the virtual environment is not stopped in two minutes, the system forcibly kills all the processes in the virtual environment. The virtual environment will be stopped in any case, even if it is seriously damaged. To avoid waiting for two minutes if you are operating a virtual environment that is known to be corrupt, you may use the Power Off link. that is situated in the Tasks section of the virtual environment dashboard.

Suspending and Resuming Virtual Environments

A virtual environment can be suspended or resumed like an ordinary computer. Depending on the virtual environment state, only those operations are accessible that comply with its current state. For example, a running Container cannot be resumed for obvious reasons, and so on.

You may temporarily suspend the virtual environments if you need to restart the physical server hosting them. After the restart, the virtual environments can be easily resumed.

To suspend a virtual environment, you can do one of the following:

• Expand the name of any physical server listed under the Infrastructure or Logical View items

in the left Parallels Virtual Automation pane and choose Suspend from the Parallels Virtual Automation context menu.

• Click the Suspend button in the Tasks section on the virtual environment Summary tab.

• Click the Infrastructure item, go to the Virtual Environments tab, select the check box to the

left of the virtual environment you want to suspend, and click the Suspend button.

• Select a physical server, go to the Containers or Virtual Machines tab (it depends on the

virtualization software installed on the physical server), select the check box to the left of the virtual environment you want to suspend, and click the Suspend button.

To resume a virtual environment, you can do one of the following:

• Expand the name of any physical server listed under the Infrastructure or Logical View items

in the left Parallels Virtual Automation pane and choose Start from the Parallels Virtual Automation context menu.

• Click the Start button in the Tasks section on the virtual environment Summary tab.

• Click the Infrastructure item, go to the Virtual Environments tab, select the check box to the

left of the virtual environment you want to resume, and click the Start button.

• Select a physical server, go to the Containers or Virtual Machines tab (it depends on the

virtualization software installed on the physical server), select the check box to the left of the virtual environment you want to resume, and click the Start button.

Managing Virtual Environments

Changing Virtual Environment Root/Administrator Password

A virtual environment(s) administrator can benefit from the Change Password option on the screen where, to perform this operation, you should enter a new root/Administrator password for the current virtual environment into the fields provided and click Change.

Note that Parallels Virtual Automation does not check the entered password as to its length and non-conformity to dictionary entries, so choosing a simple password rests entirely at your own risk. It is recommended to use a chaotic set of lowercase (a-z) and uppercase (A-Z) letters, digits (0-9), and punctuation marks as root/administrator password. The following punctuation marks are allowed: ! " $ % & , ( ) * + - . / ; : < = > ? [ \ ] ^ _ { | }. The space character, #, and @ symbols are not allowed. The password should not be less than 5 or more than 14 characters.

Note: The password of the Virtuozzo servers administrator proper can be changed on the Personal Settings tab of the User Profile screen which is displayed through the User Profile link on the right of

the Parallels Virtual Automation toolbar.

Setting Power Panel Access for Customers

Providing a particular customer with an access to a particular virtual environment stands for sending the customer the virtual environment Administrator/root login and password after the virtual environment has been created. The privacy of this information ensures the customer being the only user of the subject virtual environment.

Parallels Virtual Automation does not provide any built-in instruments for binding a specific customer to a concrete virtual environment.

When creating a virtual environment, please be aware of the notes concerning the control panels functionality - that is Parallels Power Panel and Plesk Control Panel. Thus, the Parallels Power Panel is susceptible to the network adapter type and can be used only with the Bridges or HostOnly network adapters.

After the virtual environment creation, provide the customer with the IPv4 or IPv6 address (or hostname) and TCP port of the virtual environment proper.

Additionally, the Power Panel Policy (p. 196) functionality is aimed at creating a set of rules (i.e. a policy) that restrict users access to certain functionality in Parallels Power Panel or set limitations on performing certain operations in the virtual environment context. You can create a Power Panel policy to be assigned deliberately to a concrete virtual environment or use one and the same policy for numerous virtual environments.

Managing Virtual Environments

Managing Containers

This section contains information on how to create, use, and manage Parallels Containers.

Container Dashboard Overview

The Container dashboard is divided into five sections, each reflecting the following Container details:

Status section

The section provides the following information:

• The current status of the Container.

• The information on the resources consumption by the Container: coming close to, reaching, or

going beyond the limits set for the Container generates a resources alert.

• The current status of the templates and packages. The Container software which does not

suggest updating is marked as Up-to-date.

• The hostname of the physical server where the Container is hosted (it is possible to migrate the

Container to another one).

•

The Container last 1, 5, and 15 minutes system load averages.

• The last performed and next scheduled backups.

• The total period of time during which the Container has been on without rebooting or stopping.

With the backup or schedule a backup task.

icon, you can migrate the Container from one physical server to another, create a

Configuration section

The data to be found in the Container Configuration section have to do with the Container identity

- you can see its name and ID (you can set a new Container ID by clicking Change). Additionally, you may learn what sample defines the settings of the Container (and apply another one by clicking Change), and see what OS template the Container is based on (and update the OS template by clicking Update), and which application templates are currently installed in it (and add a new application template or remove an installed one by clicking Add/Remove).

With the Container applications or apply a new template.

icon, you can change the container name or ID, update the OS software, manage

Managing Virtual Environments

Network Configuration section

The section allows you to see:

• the Container hostname (if set);

• the information on the IP addresses of the Container eth (bridged) and venet0 (routed)

interfaces. The information is available only if the IP addresses were set during the Container creation.

With the

icon, you can change the Container hostname.

Tasks section

The section provides quick access to performing the following operations:

Operate

• Starting or stopping the Container (the Start/Stop link). Depending on the Container state, only

that operation is accessible that complies with its current state.

• Restarting the Container (the Restart link).

If you are managing a virtual environment residing on the physical server with the Linux

•

operating system installed and wish to stop your virtual environment, bear in mind that there is a two-minute timeout for the virtual environment shutdown scripts to be executed. If the virtual environment is not stopped in two minutes, the system forcibly kills all the processes in the virtual environment. The virtual environment will be stopped in any case, even if it is seriously damaged. To avoid waiting for two minutes if you are operating a virtual environment that is known to be corrupt, you may use the Power Off link.

suspending the selected Container(s): a suspended Container stays put, and so its

•

processes and services do, to be later resumed from the checkpoint. Suspending Containers is a good method to disengage the Hardware Node recourses for a certain period of time or saving the state of current operations which can be quickly launched again afterwards. Remember, that repairing, restarting and reinstalling a suspended Container can change the saved state of the Container, so these actions are not recommended for suspended Containers.

Note: The availability of the start/stop/restart/suspend operations depends on the Container current status. Both PVA Control Panel and Power Panel display the same operations (start/stop/restart/suspend) being available at a moment.

replaced, or deleted any file that is part of an application or OS template, and the action has brought about the Container malfunction (the Reinstall link).

• Moving the Container to another physical server or converting it into a virtual machine (the

Migrate link).

Resources section

The section summarizes the information on the current consumption of the CPU, memory and disk share allocated to the Container: the Resources column lists these resources, the Used, Free, and Total columns display the corresponding values in percentage terms and in diagrams. The percent value is calculated not in proportion to the total disk space of the Hardware Node, but in proportion to the quota on using the Node disk space by the Container.

Note: CPU and memory statistics for Windows-based Containers will be displayed as "n/a" if performance counters are disabled on the hardware node.

Apart from the operations available in the Tasks section, the Parallels Virtual Automation toolbar provides you with access to the following operations:

• starting or stopping the Container (the Start/Stop link);

• restarting the Container (the Restart link);

• backing up the Container (the Backups link on the Manage menu);

Creating Containers

Having chosen to create a Container as described in Starting to Create Virtual Environments (p.

55), you can proceed to define general and network settings, customize and validate resource settings, install applications, and review the resulting configuration. This section describes these operations in detail.

Defining General Settings

The second page of the New Container wizard enables you to define the Container general settings that are divided into several groups for your convenience. You can choose between creating a single Container and multiple Containers by entering the necessary number on the first step of the Container creation wizard, and it is only in the latter case that the Multiple Container Configuration group is displayed.

The General Configuration group enables you to perform the following operations:

• Provide a name and a description for the Container; available when configuring settings for a

single Container only. If you need a specific name and description for one of Containers created simultaneously, you can assign them after the Containers are created (p. 107).

• Choose an OS template and its version you wish the Container to be based on.

• Start the Container after its creation;

The Multiple Container Configuration group appears if you are creating more than one Container at a time. Following is an explanation of the five drop-down menus that you find in this group:

• Container IDs

Option Description

Assign Container IDs automatically Parallels Virtual Automation will assign Container IDs randomly.

Assign Container IDs starting from a specified one On the following screen, you will be able to specify the

Set Container IDs manually On the following screen, you will be able to specify the

Container IDs manually for each Container.

• Names

for assigning Container hostnames, with the Container ID as the changing part.

Set hostnames manually for every Container On the following screen you will be able to specify the

Container hostnames manually for each Container.

• Routed Interface IP Addresses

Assign according to the Container template The host-routed interface settings are taken from the

Container template used to create the Containers. These settings just define if the host-routed interface is created inside

its IP address is taken from the global IP addresses pool.

Get from the global IP addresses pool The IP addresses for the host-routed interfaces will be taken

from the global pool of IP addresses (that can be configured on the IP Address Pool tab of the Setup --> Network screen).

Assign from a specified IP addresses range On the following screen you will be able to specify the IP

address for the first Container created. All the remaining Container IP addresses will be assigned based on the sequential incrementation of this first IP address.

Specify manually for every Container On the following screen you will be able to specify the IP

addresses manually for each Container.

• Bridged Interface IP addresses

Assign according to the Container template The bridged interface settings are taken from the Container

template used to create the Containers. These settings define the number of bridged interfaces to be created inside each Container, and if this number is 1 or more, whether their IP addresses are received from the DHCP server or is taken from the global IP addresses pool.

Get from the DHCP server The IP addresses for the bridged interfaces will be received

from the DHCP server.

Get from the global IP addresses pool The IP addresses for the bridged interfaces will be taken from

the global pool of IP addresses (that can be configured on the IP Address Pool tab of the Setup --> Network screen).

Assign from a specified IP addresses range On the following screen you will be able to specify the IP

address for the first Container created. All the remaining

Managing Virtual Environments

sequential incrementation of this first IP address.

Specify manually for every Container On the following screen you will be able to specify the IP

addresses manually for each Container.

In the Administrative Password group, you should define and confirm the root/Administrator password. You will need this password to access the Container in the future, for example, through Parallels Power Panel.

Note: Remember that each virtual environment user with the privileges of an administrator exercises full control over his/her virtual environment, has his/her own user credentials (name and password) to access the virtual environment and enjoys an unlimited access to other user accounts inside this virtual environment, i.e. s/he has any right granted to a privately owned physical server as opposed to the physical server administrator's authority or the rights of the other virtual environments users in regard to the given virtual environment. Any virtual environment user can be a member of an Active Directory domain (e.g. access any of the network shares to which the virtual environment user has rights).

The Advanced Configuration group allows you to do the following:

• Specify the Container ID, a 32-bit (ranging from 0 to 4294967295) integer number over 100.

This option is available only if you are creating a single Container. For detailed information on Container ID allocation, see the Parallels Containers for Windows User's Guide.

WARNING! When deciding on a Container ID, do not use the ID of any Container that was ever present in the system unless you are sure that no data belonging to the old Container remains on the physical server. The fact is that the administrator of the newly-created Container might have access to these data in this case, i.e. to the backups of the old Container, its logs, statistics, etc.

• Specify the paths to the Container Private Area and Root Directory;

• Have the Container started on every boot of the physical server.

The Capabilities subgroup of options in the Advanced Configuration group appears if you are creating more than one Container at a time. It enhances the operation of the Windows-based Containers you are creating by providing you with the ability to:

• Switch on the network browsing feature for the Container being created. The Windows 2003

browser service allows the Container on a Windows 2003 network to view the whole network environment available. The browser service maintains a list (called the browse list) of all available domains and computers. The browse list can be viewed using Windows 2003 Explorer and is provided by a browser in the Container. The default for the feature is the off status. You can learn more on the option from the Network Places overview article of the Windows 2003 Help system invoked by selecting Help and Support on the Windows Start menu.

• Allow the packet QoS scheduler for the Container. This is one of the Quality of Service

components in MS Windows 2003 Server that enable differentiation and preferential treatment for subsets of data transmitted over the network. The packet scheduler is the traffic control module that regulates how much traffic various applications are allowed, essentially enforcing the QoS parameters that are set for each particular application. For instance, you can use the feature to restrict a web site throughput to a certain maximum bandwidth value or differentiate between the data transmitted by critical applications (e.g. Plesk) and excessive data (e.g. multimedia applications), and allow preferential treatment for the important web sites or critical

Managing Virtual Environments

applications. The option is disabled by default. For additional information on the packet scheduler, address the MSDN Library > Win32 and COM Development > Network Protocols > Quality of Service (QOS) (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/qos/qos/qos_start_page.asp).

Note: The concept of Quality of Service in MS Windows 2003 Server differs from that of Virtuozzo Quality of Service used to provide a fair share of the main system resources (disk space, CPU time, etc.) among Containers.

• Have the Container ID displayed on the Container desktop when connected to it by the RDP

protocol.

• Enable/disable the Microsoft Cluster Server (MSCS) software to run inside the Container. The

MSCS software integrated into the Windows Server 2003 operating system is designed to allow servers to work together as one server, thus, providing greater reliability for your applications and services. Running one and the same application on two or more servers in the cluster helps ensure high application availability if one of the servers fails. The clustering software controls the failover process so that the application continues running on the second server without any loss of data and without interruption in service. The Virtuozzo Containers software allows you to include Containers in a server cluster so that they can act as full participants (nodes) in the cluster. To learn more about the MSCS software, address MSDN Library > Servers and

Enterprise Development > Windows Server > Windows Server 2003 > Technical Articles > Introducing Microsoft Cluster Service (MSCS) in the Windows Server 2003 Family

(http://msdn2.microsoft.com/en-us/library/ms952401.aspx).

To enable/disable any of the features listed under the Advanced Configuration group, select/clear the corresponding check box.

The Terminal Services group allows you to define in which one of the two standard Windows TS modes (Remote Desktop for Administration and Terminal Server) the created Containers will operate. By default, any Container is automatically set to work in the Remote Desktop for Administration mode during its creation. So, you do not need to perform any additional operations to start connecting to Containers using this mode. Like in any other system with Windows Server 2003 installed, the Remote Desktop for Administration mode allows you to simultaneously open no more than two remote sessions and a console session to any Container on the physical server.

If you are planning to have more than 2 remote sessions to a Container at the same time, you should enable the Terminal Server mode for this Container. You may also need to switch on this mode in case some of the Container applications require Terminal Server for their functioning. While set in the Terminal Server mode, the Container starts using the same Terminal Server License (TSL) server as the physical server does. So, you can log in to the Container in this mode provided the TSL server for the physical server is accessible by the Container and has a number of free client access licenses (CALs) installed. You can also redefine the TSL server to be used by the Container or set additional TSL servers for it in the License Server Address field.

The Offline Management group allows you to set the offline service options by selecting the appropriate option. Offline Service of the corresponding Container ensures the Container manageability by means of one or more offline services from any browser at its own IP address. After offline service is enabled for the Container, one port of its IP address becomes permanently active whatever the Container state. The currently supported services are Parallels Power Panel

Managing Virtual Environments

and Plesk Control panel (for managing Containers with the Plesk control panel installed in them). You can:

• Disable the offline service of the Container.

• Enable the offline service of the Container via the offline service settings operating on the

physical server. Whenever you need to manage the Container offline, its offline service settings will be brought into synchronization with those in effect on the physical server. Should any service be removed from the default services list, the Container will be unable to be managed via the service off the list. This option subscribes the Container to the default offline services.

• Manually compose the Container offline services list. You can select the service(s) you would

like the Container to be subscribed to in the corresponding checkbox(es).

The Permissions group lets you create one or more permissions for the Containers to be created. As any permission is by definition a combination of a user or a group of users and a role in respect of a certain Parallels Virtual Automation object, you can indicate the corresponding user/group and role in the provided fields, thus creating a permission with respect to the Containers being created. To add more permissions, click the green plus sign to the right of the fields.

Click Next to submit the settings and move on to the next New Container wizard stage.

Specifying Multiple Container IDs, IP Addresses, and Hostnames

The New Containers: Multiple Configuration screen comes after determining the general Container settings.

You need to set the following:

• Container IDs. Depending on what you have specified on the General Settings screen, you will

let Parallels Virtual Automation assign Container IDs automatically or will need to manually specify the starting Container ID, or every Container ID.

• Container Names and Hostnames.

When assigning Container names and hostnames, remember that both fields should contain the @ctid@ tags. Those tags will be automatically replaced with suitable IDs for all Containers you are creating. For example, if you are creating 4 Containers and have entered MYCT@ctid@ in the hostname field, and 105 is the highest Container ID on the hardware node, then Containers with the following hostnames will be created: MYCT106, MYCT107, MYCT108, and MYCT109.

• Network parameters.

The IP addresses can be assigned, if at all, either manually or on the "start from the one specified" basis, which means entering an IP address only once for the 1st Container of the Containers you are creating, with all the rest of the Containers IP addresses being calculated from this one. If you are creating 4 Containers and have entered 10.10.0.1 to the IP Address

/ Subnet Mask field, then the Containers will be created with these IP addresses: 10.10.0.1,

10.10.0.2, 10.10.0.3, and 10.10.0.4.

Click Next to proceed to customizing Container resources.

Managing Virtual Environments

Configuring Container Network Parameters

The Network Configuration page lets you define all the major network parameters of the Container you are creating. For more information, see Configuring Container Network Parameters (p. 229).

Customizing Resource Settings

The Resources Customization screen allows you to adjust the resources the Container being created. For more information, see the descriptions of Linux-related CPU (p. 75), disk (p. 76), and memory (p. 78) resources; or Windows-related CPU (p. 75), disk (p. 77), and memory (p. 80) resources.

The system resource control parameters have complex interdependencies, or constraints. Violation of these interdependencies can be catastrophic for the Container. In order to ensure that the Container under creation does not break them, it is important to validate the Container configuration file before creating Containers on its basis.

The utility checks constraints on the resource management parameters and displays all the constraint violations found. There can be three levels of violation severity, represented by the following icons on the Container dashboard:

Recommendation

This is a suggestion, which is not critical for the Container or physical server operations. The configuration is valid in general; however, if the system has enough memory, it is better to increase the settings as advised.

Warning

A constraint is not satisfied, and the configuration is invalid. The Container applications may not have optimal performance or may fail in an ungraceful way.

Error An important constraint is not satisfied, and the configuration is invalid.

The Container applications have increased chances to fail unexpectedly, to be terminated, or to hang.

After setting the reasonable values for the parameters, the Container can be safely run.

Installing Applications into Containers

The New Containers: Application Selection page of the New Container wizard allows you to choose applications to install them to the Container directly after its creation. All available applications that can be added to the Container are listed in the Available Applications table in the left part of the displayed page. The type and number of applications vary depending on the OS template the Container will be based on, i.e. only those applications are displayed that are compatible with the Container OS template.

Managing Virtual Environments

To add the applications you need to the Container, tick the check boxes opposite the applications you wish to add and click the >> button. After that, the applications appear in the Scheduled for Installation table in the right part of the page. To remove any application from the Container being created, tick its check box in the Scheduled for Installation table and click the << button. If you are not sure what applications you need to add to the Container, you can add them after the Container has been created, as is described in Managing Container Applications.

After you have selected the applications to be installed and checked their dependencies, click the Next> button.

Reviewing Container Configuration

The last page of the New Container wizard lets you review the major settings of the Container configuration you provided on the previous steps. If you are satisfied with the information entered, click Create to start creating the Container. Otherwise, you can return to the previous steps by clicking the Back button and change the corresponding parameters.

Logging In to Containers

Accessing Containers via Parallels Power Panel

Parallels Power Panel is the tool designed for the administrators of a particular Container. A Parallels Virtual Automation user can also use it to take a closer look at a particular Container (provided the corresponding rights are granted to them).

Parallels Power Panel can be opened in one of the following ways:

• On a list of Containers, right-click the needed Container, then select Log In -> Open Parallels

Power Panel;

• On the Container dashboard, select Log In -> Open Parallels Power Panel on the top

toolbar;

• On the Container dashboard, click Open Parallels Power Panel in the Tasks group of links.

Sometimes it is not possible to open Parallels Power Panel due to the following reasons:

• An IP address might not be assigned to the corresponding Container;

• Offline service might be disabled globally on the physical server;

• Offline service might be disabled for the corresponding Container (though enabled globally).

So, to make sure Parallels Power Panel can be opened for any Container, you should enable Offline Service both globally and for the particular Container, as well as assign this Container an IP address.

Managing Virtual Environments

Accessing Containers via SSH

You can use the Secure Shell (ssh) application to remotely connect to running Containers and work in their directory trees using standard Linux command line tools. To connect to a running Container via ssh, make sure you have the Java Virtual Machine installed on your computer (you can also launch Parallels Virtual Automation in the Internet Explorer). For more information, see Accessing Physical Servers via SSH (p. 46).

Notes:

1. If your Container is running a Windows Server operating system, see Accessing Containers via RDP (p. 70) to learn to manage Containers by means of Remote Desktop Connection.

2. To learn the port numbers that should be open to ensure a successful SSH connection, refer to http://kb.parallels.com/en/9516.

Accessing Containers via VNC

In Parallels Virtual Automation,The VNC Console screen displays the VNC console opened to the Container. You can use the Refresh button to update the displayed information, if necessary.

If the VNC connection to the Container could not be established, check the following:

• The Sun Java(TM) plug-in and JRE are installed and enabled in your browser.

• The server where the Container resides is running Parallels Cloud Server.

• The Container is running.

Accessing Containers via RDP

You can use Remote Desktop Connection, a standard Windows tool, to connect to a running Container via the Remote Desktop Protocol (RDP). The feature is only available for the Internet Explorer. For more information, see Accessing Physical Servers via RDP (p. 47).

Notes:

1. For Linux-based Containers, see Accessing Containers via SSH (p. 46) to learn to manage the Container by means of Secure Shell.

Managing and Monitoring Container Resources

To open the Container Monitor subtab, go to Infrastructure > physical server > Container > Resources tab > Container Resources subtab.

Managing Virtual Environments

The Container Monitor screen shows the graphical statistics on CPU, memory and disk resource consumption in percentage, i.e. how much of the physical server resources this Container consumes.

Also, the Container Monitor screen allows viewing the disk and traffic incoming/outgoing statistics for the specified period.

Each resource has its own colour on the chart. If you need to monitor the changes only for one resource, whatever it is, you can disable the others. Use the Select Graph subsection.

The chart shows the changes for the defined period. In the Graph Period subsection, select whether to show the data for a particular date, month, year or for any other period of time. To implement the changes, click Apply. The chart will change its appearance.

Partially, the information on resource consumption is available on the Container Summary page (p.

59).

The Export Data link allows you to export the graphical data in the CSV format.

Note: The Container network and system resources can also be monitored via SNMP. For more information, see Monitoring Parallels Objects via SNMP (p. 284).

Resources Overview

The Overview subtab summarizes the current CPU, system and disk usage by the Container in the following table:

CPU Usage This figure shows current CPU utilization in percent.

Load Average for the CPU usage is the average number of active processes for the past 1, 5, and 15 minutes, respectively. Value 0.0 means that the CPU is idle, 1.0 that the CPU is fully used. Value 2.0 denotes that the CPU load exceeds the nominal value by two times.

Memory Usage This is a cumulative figure presenting the average consumption of a number of critical memory-

related parameters by your Container.

Disk Usage Disk Space is a total amount of disk space allocated to the Container. When the space used by

the Container hits the soft limit (or reaches 100% on the percent bar), the Container can be allowed additional disk space up to the hard limit during the grace period.

Disk I/O is a cumulative figure presenting how much of the allowed disk i/o bandwidth is used by the Container and how much is still available up to the limit.

The information on the disk and memory usage is organized as follows:

Column Name Description

Resource The name of the resource: memory, disk space, disk i/o bandwidth or disk inodes.

Used Consumed amount of memory, disk size, disk /o resource or the number of inodes.

Free Available amount of memory, disk size, disk /o resource or inodes number.

Total The total amount of memory, disk size, disk /o resource or inodes.

Linux-related Memory Resources

This screen displays information on the memory-based or system-based virtual environment resources, or both, depending on your memory configuration:

• If the memory management mode is enabled for the virtual environment, it can be allocated

memory in much the same way as a certain amount of physical memory is installed on a physical computer. This is the recommended mode for managing virtual environments for most administrators.

• If the system management mode is enabled, the virtual environment's performance depends on

the values of quite a number of fine-grained parameters. The primary parameters are the starting point for defining the relative power of a virtual environment. The secondary parameters are dependent on the primary ones and are calculated from them according to a set of constraints. The auxiliary parameters help improve fault isolation among applications in a virtual environment and the way applications handle errors and consume resources.

• If both resource management modes are used, the more restrictive value is taken into account

each time the system makes the decision whether to allocate this or that resource to the virtual environment.

Memory parameters

Parameter Description

slmmemorylimit

An approximation of the size of the physical memory allocated to the virtual environment. In other words, the virtual environment performance is similar to the performance of a physical computer with as much physical memory installed as is indicated in this parameter.

Primary system parameters

Parameter Description

numtcpsock

numothersock

vmguarpages

The maximal number of processes the virtual environment may create.

The number of TCP sockets (PF_INET family, SOCK_STREAM type). This parameter limits the number of TCP connections and, thus, the number of clients the server application can handle in parallel.

The number of sockets other than TCP ones. Local (UNIX-domain) sockets are used for communications inside the system. UDP sockets are used, for example, for Domain Name Service (DNS) queries. UDP and other sockets may also be used in some very specialized applications (SNMP agents and others).

The memory allocation guarantee, in pages. r applications are guaranteed to be able to allocate additional memory so long as the amount of memory accounted as privvmpages (see the auxiliary parameters) does not exceed the configured barrier of the vmguarpages parameter. Above the barrier, additional memory allocation is not guaranteed and may fail in case of overall memory shortage.

The average number of processes and threads.

Secondary system parameters

dgramrcvbuf

numfile

numflock

dcachesize

numiptent

Parameter Description

kmemsize

The size of unswappable kernel memory allocated for the internal kernel structures for the processes of a particular virtual environment.

Note: For the Parallels Containers 64-bit version for IA-64 processors, it takes 4 (four) times more the size of the kernel memory than that for the Parallels Virtuozzo Containers 32-bit version to handle one and the same process.

tcpsndbuf

tcprcvbuf

othersockbuf

oomguarpages

privvmpages

The total size of send buffers for TCP sockets, i.e. the amount of kernel memory allocated for the data sent from an application to a TCP socket, but not acknowledged by the remote side yet.

The total size of UNIX-domain socket buffers, UDP, and other datagram protocol send buffers.

The total size of receive buffers of UDP and other datagram protocols.

The out-of-memory guarantee, in pages. Any virtual environment process will not be killed even in case of heavy memory shortage if the current memory consumption (including both physical memory and swap) does not reach the oomguarpages barrier.

The size of private (or potentially private) memory allocated by an application. The memory that is always shared among different applications is not included in this resource parameter.

Changing Container Resource Parameters

This screen allows you to adjust the resources of the selected virtual environment. For more information, see the descriptions of Linux-related CPU (p. 75), disk (p. 76), and memory (p. 78) resources; or Windows-related CPU (p. 75), disk (p. 77), and memory (p. 80) resources.

You can also edit Container resource values via ssh by using the vzctl utility. You will need to use the --save option to have the edited UBC parameters reported by Parallels Virtual Automation or Parallels Power Panel. For more information, see the Parallels Virtuozzo Containers

Reference Guide.

Changing Disk Quota for Multiple Containers

You can specify a new disk quota for a bunch of your Containers at once on the Configure: Set Container Disk Limits page.

The Containers Disk Usage Current Statistics table lets you take in the current disk quota and usage for all the selected Containers at a single glance.

In the Change Containers Disk Quota group there are three major options to set a defined disk quota for the Containers:

• Use the Set Disk Quota to option to specify an exact size of the disk space each Container is

allowed to consume.

• Use the Increase Disk Quota by option to have the quota increased by a specified amount for

each Container. So, if two or more Containers had different disk quotas before, the latter will remain different because the increase is the same.

Managing Virtual Environments

• Use the Decrease Disk Quota by option to have the quota decreased by a specified amount

for each Container. So, if two or more Containers had different disk quotas before, the latter will remain different because the decrease is the same.

To further tune the disk usage, set the inodes limit you think is reasonable for the total number of files you have or are going to have on each Container disk. In the Change Containers Disk Inodes Limit group you can:

• Set an inodes density value and use the Calculate the disk inodes limit using the inodes per

KB ratio option;

• Set an inodes limit value to depend on the current Container inodes density;

• Manually enter an inodes limit value;

Just enter the desired number into the corresponding field, choose the proper units of measurements and click Submit.

Note: When performing the operation, bear in mind that the disk quota for a Container cannot be less than the size of the disk space already occupied by this Container (you can learn it from the Resources table on the Summary tab).

The two remaining options in both groups speak for themselves - select Set unlimited Disk

Quota/Inodes to remove any disk space/inodes restrictions for the selected Containers, or select Do not change Disk Quota/Inodes Limit to leave the current disk space restrictions intact.

Applying New Container Templates

Any Container is configured by means of its own Container template (a configuration file used as an archetype to reproduce all its settings for a Container based on it). The Apply template to Container page enables you to change the Container template the Container is based on and, thus, to change all the resources the Container may consume and/or allocate at once.

In the Original Container template table at the top of the page, you can view the name and description of the current Container template the Container is based on (

available currently for the Containers running the Windows operating system).

The Select Library Container template table allows you to choose another configuration template to base the Container on by selecting the radio button against the corresponding Container template. All available Container templates listed are supplied with the following information: the name and brief description of the Container template.

To facilitate working with Container templates, you may have the Select Library Container template table display only those Container templates that have the corresponding name or a certain word in their description. On top of the table, press the Show Search link to display the fields where you can specify the parameters the given Container template should meet; then click on the Search link.

• To learn how to manage services in virtual environment running the Windows operating system,

please see the Managing Services in Windows subsection.

Managing Virtual Environments

Managing Services in Linux

The System Services SysV subtab is used to view all the services you are running on the Container except for the xinetd-dependent services. To see the xinetd-dependent services list, click the System Services Xinetd subtab. By default, 20 services are shown on the screen, but you may have more services displayed by pressing the appropriate link on top of the table. You may also have the System Services table display only those services that have a particular name or status. On top of the table, press the Show Search link to display the fields where you can specify the name or the status of the service you wish to view; then click on the Search link. You can have Parallels Virtual Automation display only those parameters you need at the moment. To show or hide certain columns, click the Select Columns link and select the parameters you want to be displayed or clear those you do not.

The System Services SysV screen presents a table reflecting the services inside the Container and providing the following information:

Column Name Description

Name The system ID of the service executable file.

Status Indicates whether the service is running or not. A green arrow means that the service is running;

a red cross - that it is stopped.

Autostart If there is a green tick in this column, this service is started automatically on the Container

startup; if a red cross - it is not.

Note: This table displays only those services that are listed in the configuration file etc/opt/pva/cc/standart-services.xml. placed in the Container directory /vz/root/1.

With the help of the Parallels Virtual Automation toolbar you can perform the following actions on any service in the table:

• Start the service by selecting its check box and clicking Start Service.

• Restart the service by selecting its check box and clicking Restart Service.

• Stop the service by selecting its check box and clicking Stop Service.

• Enable/disable the autostart feature by selecting the service(s) and clicking Enable/Disable

Autostart.

All the above and a service description are available on the screen which opens by clicking the name of the service in the Name column.

Note: If you have just started the Container and opened the Services page, not all the services may have had enough time to start. Wait a little and refresh the page to update the state of the services.

Managing xinetd-Dependent Services

The System Services Xinetd subtab is used to view all the services you are running on this Container that are dependent on the xinetd service. To see the other services, click the System Services SysV subtab. By default, 20 services are shown for each tab, but you may have more services displayed by pressing the appropriate link on top of the table. You may also have the

Autostart

Note: This table displays only those services that are listed in the configuration file etc/vzcp/standart-services.xml. placed in the Container directory /vz/root/1.

If there is a tick in this column, the xinetd service is started automatically on the Container startup, so is the given service; if a cross - it is not.

You can perform the following actions on any service in the table:

• Enable the service by selecting its check box and clicking on the Enable button on the Parallels

Virtual Automation toolbar. Only disabled services are subject to this action.

• Disable the service by selecting its check box and clicking on the Disable button on the

Parallels Virtual Automation toolbar. Only enabled services are subject to this action.

Viewing Service Details

The Service Details screen provides the principal information on the given service and lets you manage it.

The following information is provided:

• The description of the service;

• Whether the service is running or stopped;

• Whether the service is started automatically on the Container startup or not.

You may perform the following actions on any such service:

• Stop the service by clicking the Stop Service button. Only running services are subject to this

action.

• Restart the service by clicking the Restart Service button. Only running services are subject to

this action.

• Start the service by clicking the Start Service button. Only stopped services are subject to this

action.

Managing Virtual Environments

• Enable/disable the autostart feature by clicking the Enable Autostart/Disable Autostart

button, correspondingly.

Viewing xinetd-Dependent Service Details

The Service Details screen provides the principal information on the given service and lets you

manage it.

As the service is dependent on the xinetd service, i.e. xinetd is charged with launching the service when necessary, you can only either enable or disable such a service — depending on its current state — by clicking the Enable/Disable Service button, correspondingly. Moreover, the xinetd service must be running to perform any such action; otherwise, the operation will result in an error. You cannot manage the autostart feature of xinetd-dependent services, as its value is inherited from the xinetd service.

Managing Services in Windows

The System Services page is displayed when clicking the System Services link on the Services tab of the Container dashboard. It presents the table reflecting those services inside your Container that you can manage. The table provides the following information:

Column Name Description

Name The name of the service running inside your Container.

Status Indicates whether the service is running or not.

Startup Type Indicates whether:

The service is started automatically on the Container startup; The startup type of the service is set to SERVICE_DISABLED;

The service can be launched only manually.

Logon as

Indicates the user account (the LocalService account, the NetworkService account, etc.) that was used to start the service.

You can perform the following operations on any service in the table:

• Stop the service by selecting its check box and clicking on the Stop button.

• Restart the service by selecting its check box and clicking Restart.

• Start the service by selecting its check box and clicking on the Start button.

• Open the Services Details page to enable/disable the autostart feature by clicking on the

name of the service in the Name column.

To facilitate working with Container services, you may have the System Services table display only those services that have a particular name, startup type (automatic, manual, disabled), are in a certain state (running or stopped), or were started by a certain user. On top of the table, press the Show Search link to display the fields where you can specify the parameters your services should meet; then click on the Search link. To view all the services currently running inside your Container, click on the Reset Results link to the right of the Search link. You can have Parallels Virtual Automation display only those parameters you need at the moment. To show or hide certain

Managing Virtual Environments

columns, click the Select Columns link and select the parameters you want to be displayed or clear those you do not.

Viewing Service Details

The Service Management page opened on clicking the name of the service you have selected on the System Services page allows you to change the startup type of your Container services:

• Make a service automatically start on the Container startup by selecting Automatic in the drop-

down list of the Startup Type field and clicking on the Submit button.

• Set a service as "manual" meaning that you should start the service manually before it can be

loaded by the operating system and made available for use. To this effect, select Manual and click on the Submit button.

• Disable a service by selecting Disabled in the drop-down list and clicking on the Submit

button.

Note: Changing the default service settings might prevent key services from running correctly. It is especially important to use caution when changing the startup type of services that are configured to start automatically.

In the Dependencies section you can find out what system components depend on the selected service. You can also view the system components your service depends on, if there are any. You should always take into account the service dependencies before changing its settings. This information is very important since if a service is stopped or is not functioning properly, the dependent services may also be affected.

Managing Container Processes

The System Processes page is displayed when clicking the Service > System Processes link. It presents a table reflecting all the running processes inside the Container. The table provides the following information:

Column Name Description

PID The process ID.

%CPU The percent of the CPU time the process is currently using.

%MEM

Command The command that is used to launch the process.

Nice

Pri The absolute priority of the process assigned to it by the process scheduler. On a Linux physical

The percent of the RAM size the process is currently using.

The relative priority of the process assigned to it by the user. The negative values mean that the user has manually increased the priority, the positive values - that they have decreased it.

server, the range is from 0 (the highest priority) to 39 (the lowest priority). The usual process priority is 30. On a Windows physical server, the range can be from 0 (the highest priority) to 31 (the lowest priority). The usual process priority is 8.

Managing Virtual Environments

RSS (Resident Segment Size) The size of physical memory the process really uses (in Kilobytes).

Stat

Time The total amount of the CPU time the process has used so far.

User The user the process belongs to.

The state of the process. The possible states are: R - runnable, on the run queue; S - sleeping; T traced or stopped; D - uninterruptable sleep; Z - defunct, "zombie". If two letters are shown, the second letter means the following: W - has no resident pages; < - high-priority process; N - lowpriority task; L - has pages locked in memory; s - the process is a session leader; "+" means the process is in the foreground process group of its control terminal.

To have the information in the table refreshed automatically with the current values, click the Enable Autorefresh button. It is worthy to note that only the table on the current page is refreshed, which takes much less resources in comparison with refreshing the whole Parallels Virtual Automation page.

Note: The table is available only for a running Container. If the table cannot be accessed, Power Panel suggests possible actions.

On a Windows physical server, you may select any number of processes by ticking the check boxes against the corresponding processes (tick the uppermost check box to select all the processes at once) and end them by clicking the End Process button.

On a Linux physical server, you may select any number of processes by ticking the check boxes against the corresponding processes (tick the uppermost check box to select all the processes at once) and send them a standard signal. Choose the needed signal on the drop-down menu and click the Send Signal button. The following signals can be sent:

• SIGHUP - is a hang-up signal. It is often used to ask a daemon process to re-read its

configuration.

• SIGTERM - sends the termination signal to the process. This is the best way to give the

process a chance for an orderly shutdown and proper data saving. As the process might be able to catch this signal and stay alive, you may have to make use of the sigkill or sigint signals.

• SIGCONT - continues the process causing it to resume.

• SIGSTOP - stops (suspends) the process. The process will still be on the task list.

• SIGINT - causes the process to immediately interrupt. The signal is very close to sigkill,

the difference being that, unlike sigkill, it can be caught by the process and ignored if the process gets out of hand. In this case you should send sigkill to shut down the process.

• SIGKILL - unconditionally kills the process. Mind that sending sigkill to any process

removes any chance for it to do a tidy cleanup and shutdown, which might have unfortunate consequences.

Managing Virtual Environments

Managing Container Applications

Applications can either be added to the Container by means of the corresponding Parallels Virtuozzo templates or installed in the Container as individual software packages.

The Applications subtab of the Container Software tab allows you to do the following:

• view the applications added to the Container as application templates (both EZ and standard)

as well as their up-to-date status.

• if some of the applications are not up to date (i.e. the updated versions of the corresponding

templates or template packages are available on the physical server), update them by clicking the Update Container Software button on the toolbar.

• add more applications available on the physical server or delete unnecessary ones by clicking

Manage Applications and performing these actions on the screen that opens.

Managing Container Application Templates

The Manage Applications button on the Applications subtab of the Container Software tab opens the screen that allows you to manage applications available to the Container. On this page, you can:

• View the applications already installed in the Container. These applications are listed in the

Installed/Scheduled Applications table in the right part of the page.

• Install new applications to the Container. To add any of the applications from the Available

Applications table to the Container, tick the corresponding check boxes and click on the >>

button. After that, the applications appear in the Installed/Scheduled Applications table in the right part of the page. Clicking the Submit button starts the installation process.

• Delete those applications from the Container that are not needed any more. To remove any

application, tick the corresponding check box in the Installed/Scheduled Applications table and click on the << button. After that, the application appears in the Available Applications table in the left part of the page. Click the Submit button to start the deletion process.

Check unresolved dependencies among the selected applications with the help of the

•

Resolve button. To eliminate unresolved dependencies, you can remove one of the problem applications from the Installed/Scheduled Applications table as explained above.

Note: Only standard template based Container application dependencies require resolving. If you are managing a Container based on an EZ template, the Resolve button is not present on the screen.

Adding Application Templates to Multiple Containers

It is possible to add one or more application templates simultaneously to a multitude of Containers on the Configure: Add Software to Containers page (accessible by selecting the Containers on the list, clicking Configure and selecting the Add Software to Containers option). The available templates are listed in the Select Applications to Install group. There are two conditions for being able to add the templates listed under that group to the Containers in question:

Managing Virtual Environments

1 They should be installed on all the physical servers where the respective Containers are

situated.

2 They should be compatible with all the Containers for which this operation is performed.

Select the check boxes beside those applications that you want to add to the Containers. You also have the option to start those Containers that are stopped to be able to add the templates to them. Otherwise, the templates will not be added to the Containers that are not running.

Click Next to review your operation details and start the software installation.

Removing Application Templates From Multiple Containers

It is possible to remove one or more application templates simultaneously from a multitude of Containers on the Configure: Remove Software From Containers page (accessible by selecting the Containers on the list, clicking Configure and selecting the Remove Software From Containers option). The templates that are added to all the Containers in question and thus can be removed from all of them are listed in the Select Applications to Remove group.

Select the check boxes beside those applications that you want to remove from the Containers. You also have the option to start those Containers that are stopped to be able to remove the templates from them. Otherwise, the templates will not be removed from the Containers that are not running.

Click Submit to start the software uninstallation.

Managing Container Software Packages

Parallels Virtual Automation enables you to install, update, and uninstall rpm and deb packages in Containers based on EZ OS templates.

Note: The Container you want to manage software packages in has to be running.

You can obtain the information on the packages currently installed in the Container in the Installed

Packages table, presented as follows:

Column Name Description

Name The name of the package.

Epoch Indicates the version of a deb package or the version of an rpm package in case the version

of the rpm package is not available.

Version The version of an rpm package.

Arch The processor architecture; if the column shows the "noarch" value, the packet is likely to be

either non-executable or contain documentation.

Summary A short description of the package.

Status Shows if there is a fresher version of the package: Up-to-date or Update Found.

The Installed Packages table displays from 10 up to 80 packages; the default number is 20 and can be changed by clicking 10, 40, or 80 on top of the table. To see the next portion of packages,

Managing Virtual Environments

click either the number of the page next to the one you are having at the moment, or next (or last,

The processor architecture; if the column shows the "noarch" value, the packet is likely to be

to view the last page).

If the status of a package in the Installed Packages table suggests that an update is available, you can select this package and click the Update link on the Parallels Virtual Automation toolbar. To update all those packages that you can see on the page, select the uppermost check box and click Update. If you need to run update for all the packages installed in the Container, do not select anything - simply click the Update All icon on the Parallels Virtual Automation toolbar.

To uninstall a package, select it (or select the uppermost check box to uninstall all the packages listed on the page), and click Uninstall.

The Parallels Containers software can query the repository where the packages for your distribution are stored for new packages available for downloading and install them in your Container. To connect to the repository, fetch a list of the packages, see the packages description, and download and install in your Container the packages you need, click Install Packages on the Parallels Virtual Automation toolbar.

Installing Software Packages in Container

The Parallels Containers software can connect to your Linux distribution download packages repository to form a list of packages ready to be downloaded to your physical server and installed in your Container. All these operations are available on the Install New Packages screen.

Note: A repository can be a place where multiple files are located for distribution over a network, or a repository can be a location that is directly accessible to the user without having to travel across a network. Therefore connecting to your repository might involve either going to the web site repository (e.g. Fedora Core or Red Hat), or to the repository, created on your physical server. For information on creating a local repository, refer to the Setting Up Repository for EZ Templates section in the Parallels Virtuozzo Containers Templates Management Guide.

On the Install New Packages screen you can obtain the following information on the packages:

Column Name Description

Name The name of the package.

Epoch Indicates the version of a deb package or the version of an rpm package in case the version

of the rpm package is not available.

Version The version of an rpm package.

Arch

either non-executable or contain documentation.

The Available Packages table can display 10, 20, 40 or 80 packages, the default number is 20 and can be changed by clicking 10, 40, or 80 on top of the table. To see the next portion of packages, click either the number of the page next to the one you are having at the moment, or next (or last, to view the last page).

To install a package, select its check box (or the uppermost check box, to install all the packages shown in the table) and click Install.

Managing Virtual Environments

Managing Container Control Panels

There are a number of control panels that can be installed on the physical server in the form of templates and added to any Container hosted on that physical server. Among such control panels

are Plesk,

Sitebuilder, and Confixx.

The Control Panels subtab of the Software tab of the Container dashboard provides a single place for managing all these control panels in this particular Container. It goes without saying that the control panel template must be installed on the Node for the panel to be manageable on this screen.

The two major management operations that can be performed here are:

• adding the control panel template to the Container (the Install link), which ensures that this

Container can be managed by the given control panel.

• logging in to the control panel to begin managing the Container with its help (the Login link).

This is possible only if the control panel template has already been added to the Container.

Note: In the case of the Plesk control panel, the Login link is called Manage and leads to the screen where you can not only log in to Plesk but also change the Plesk admin password.

Updating Container Software

The Update Software page allows you to update the OS and application packages in the given Container by adding available templates updates (in the case of standard Container templates) or updating Container packages directly (in the case of Virtuozzo EZ templates). The Update Software page is available on clicking the Update Container Software link on the Parallels Virtual Automation toolbar, which becomes visible if you are currently located on the Application Templates subtab of the Container Software tab.

The page will display the relevant information in one of three ways:

1 If no updated templates for the given Container have been installed on the physical server or no

updated packages are found in the repository, the page just informs you of this fact.

2 If the Container uses standard Virtuozzo templates and one or more updated versions of the

corresponding template(s) are installed on the physical server, you are able to select an updated version for adding to the Container.

3 If the Container uses Virtuozzo EZ templates and updated packages for the given Container

can be found in the repository, you are able to select the packages that you wish to update inside the Container.

Two options for customizing the update process are available on clicking the Configure Updating group:

• The Force software update option tells the system to perform the update even if unresolved

dependencies are met during the process;

Managing Virtual Environments

• The Jump over several upgrades instead of adding them sequentially option can be used if

two or more sequential updates are found for this or that template.

Click Update to update the templates/packages you have selected for the given Container.

Updating Software in Multiple Containers

The OS and application packages can be updated simultaneously in a multitude of Containers by adding available templates updates (in the case of standard Container templates) or updating Container packages directly (in the case of Virtuozzo EZ templates). All the currently available OS and application packages updates will be installed to the selected Containers. This is done on the Configure: Upgrade Containers Software page. For instructions on updating Container templates, refer to Updating OS and Application.

Two actions for customizing the update process are available on clicking the Configure Updating group:

• The Force software update action tells the system to perform the update even if unresolved

dependencies are met during the process;

• There is no way to update a stopped Container. If some of the Containers you selected for

updating are not running, select the Start the stopped Containers check box. The Containers that are not running will then be started only to be updated and stopped again.

Click Update to update the selected Containers. To return to the previous page, or cancel upgrading click Back and Cancel, accordingly.

Cloning Containers

You can create a complete copy of a particular Container (in respect of all the Container data and resource parameters), or a Container clone. This is a good means to save your time since you do not bother about setting the Container configuration parameters and the like. Moreover, you can create a number of Container clones at a sitting by opening the Containers page, selecting the ones to be cloned and clicking the Clone link.

The option is available on the Clone Container page which enables you to define the name, hostname, password, offline service, and set the advanced settings for the Container being created.

The General Settings section enables you to:

• Provide a name for the Container clone.

The Network Settings section lets you:

• Set a hostname of the Container. Mind that the range of symbols for the Container hostname is

limited. underscore ( _ ), contain further any of the following symbols: a-z, A-Z, 0-9, _, - and have a-

z, A-Z, 0-9 or _ at the end. The maximum number of symbols is 15.

For a Windows Node, the hostname may start singularly with a-z, A-Z or an

For a Linux-based

Managing Virtual Environments

Container, the hostname should consist of a-z, 0-9, _, and may have a point in the middle. The number of symbols should not exceed 256.

In the New Password section, you can set a new password for the Container clone. In this case you provide the password in the Administrative password field and confirm it in the field below. You can leave the field blank though to use the password from the cloned Container. The password is needed to access the Container in the future, for example, through Parallels Power Panel.

The Advanced Settings section lets you:

• Specify the Container ID, a 32-bit (ranging from 0 to 4294967295) integer number over 100

(For more information on Container ID allocation, see the Parallels Containers for Windows User's Guide);

• Start the Container after cloning.

• Disable the offline service of the Container.

• Enable the offline service of the Container via the offline service settings operating on the

• Manually compose the Container offline services list. You can select the service(s) you would

like the Container to be subscribed to in the corresponding checkbox(es).

By default, the Offline Service radio button is set to the option used by the Container being cloned. You can change it to use another offline service mode for the new Container.

Note: The rest of the Container general settings (p. 63) are copied from the cloned Container by default.

Click Clone to initiate the creation of the Container clone or Customize to set up the remaining network settings of the new Container.

Configuring Clone Network Parameters

The Clone Container - Configure Network screen allows you to define what Virtual Network adapters the new Container will use and to configure the settings of these adapters. For more information, see Configuring Container Network Parameters (p. 229).

After deciding on the necessary parameters, click Clone to start the cloning procedure.

Managing Virtual Environments

Cloning Multiple Containers

One of the easiest methods of creating new Containers of a certain type or particular configuration is cloning the old ones. Cloned Containers are exact replicas of the prototypes and can be created on the Clone Containers screen where you can:

• Specify a name and a hostname for each new Container clone. The number of sections to set

these parameters is equal to the number of Containers you want to clone. Mind that the range of symbols for the Container hostname is limited.

For a Windows Node, the hostname may

start singularly with a-z, A-Z or an underscore ( _ ), contain further any of the following symbols: a-z, A-Z, 0-9, _, - and have a-z, A-Z, 0-9 or _ at the end. The maximum number

of symbols is 15.

For a Linux-based Container, the hostname should consist of a-z, 0-9, _,

and may have a point in the middle. The number of symbols should not exceed 256.

• If you need to start the clones immediately after they are created, select the Start the

Containers after cloning check box in the Post Procedures section.

After entering the necessary data, click Clone to begin the cloning procedure, otherwise click Cancel.

Migrating and Converting Containers

The cases when you need to move your Containers from one physical server to another can be quite numerous. A migration can be performed to distribute the workload between physical servers, etc. On the Migrate Containers screen, you need to select the physical server you are going to move the Container to and select some additional options.

A Container can be migrated to:

• Same-platform physical server with the same operating system as the Container has.

• Parallels Server Bare Metal physical server. If you migrate a Linux-based Container, you can

choose whether to convert the Container to a virtual machine or not. If you migrate a Windowsbased Container, the Container will be automatically converted into the virtual machine with the Windows operating system. This is done, because virtual machines, in contrast to Containers, can have an operating system different from the hosting physical server OS.

Note: The physical server must be registered in the infrastructure. If you need to migrate the Containers to a physical server that has not been registered yet, this has to be done first.

Irrespective of the migration case, in the Migration Options section, consider the following:

• Perform live migration to avoid service interruption. By default, the Container, if running

before the migration, is stopped. But you can leave it running even during the migration by selecting this option.

• Remove the private areas from the source Hardware Node after the migration. You can

remove the Containers private areas (the directories to store the Containers files and other data) from the source physical server when the migration is finished, which lets you free some disk

Managing Virtual Environments

space. On the other hand, you might want to leave the private areas on the source physical server intact until you ascertain the migrated Container operates normally;

• Do not start the Container after the migration. If the Container was in a running state before

the migration, it will automatically start after the migration is complete. But you can leave it stopped to perform some additional operations on it by choosing this option.

• Force the migration. Ignore possible conflicts in IP addresses applications. The Container

migration happens even if its IP address might cause conflicts on the destination physical server or if the templates the Container uses are not installed there. Keep in mind that though it is possible to force the migration of such a Container, it might not be able to start on the destination physical server until the problems with IP addresses and/or templates are resolved.

Click the Migrate button if you are ready to initiate the Containers migration, otherwise click Cancel.

Migrating Container to Virtuozzo Physical Servers

To migrate a Container to a Virtuozzo physical server, do the following:

In the Migration From section, choose the physical server that will host the Container.

1 Choose the Virtuozzo physical server that will host the Container from the To Hardware Node

drop-down list. Depending on the Container's operating system, the list will display only Windows or only Linux Virtuozzo physical servers.

Note: If you choose a Parallels Server Bare Metal physical server, you will also be able to convert the Container to a virtual machine. See the information below.

2 Specify the settings in the Migration Options section, if needed. 3 Click Migrate to continue.

Migrating Containers to Bare Metal Physical Servers

The Migrate Containers page allows you to migrate a Windows- or a Linux-based Container to a Parallels Server Bare Metal or Parallels Cloud Server physical server and to convert it to a virtual machine.

To migrate a Container to such a physical server, do the following:

1 Choose the Parallels Server Bare Metal physical server that will host the Container from the To

Hardware Node drop-down list.

The Convert Containers to Parallels Virtual Machines option appears.

If you convert a Windows-based Container to a PSBM physical server, the conversion to a virtual machine is obligatory, and the check box is automatically ticked off.

If you convert a Linux-based Container to a PSBM physical server, the conversion is not obligatory, and you can choose whether to convert the Container into a virtual machine or not.

2 Specify other Migration Options if needed and click Migrate to continue.

Managing Virtual Environments

The created virtual machine is an exact copy of the Container, i.e. it will have the same operating system and networking settings, memory size and CPU count, the whole scope of software programs and data stored in the Container, the same security and port redirection settings, etc. Moreover, the virtual machine will have the information on traffic, disk, CPU and memory usage recorded during the Containers activity.

Migrating Physical Servers to Containers

Parallels Virtual Automation provides you with an effective tool - Parallels Transporter - for a fast and reliable migration from a physical server to a Container. Migration of a stand-alone physical server to a virtual environment may be useful for a server using its available resources only partially, as the usage of the resources on the physical server hosting virtual environments is distributed efficiently among the virtual environments. Therefore the physical server is never idle at the same time allotting the virtual environments enough resources to operate. You can benefit from the physical server to virtual environment migration by:

• Cutting down administrative and operations costs. Decreasing the number of physical servers

under management reduces administrative overhead, as well as rack space, power, and hardware replacement costs.

• Reducing downtime costs. virtual environment allows you to back up your production

environment, which can be rapidly deployed in the event of a system failure.

• Optimizing resource utilization. Each server under management is fully used; its resources are

not wasted.

Improving standardization. Deployment of standard hardware allows for improved security and reliability across your organization’s network as well as the streamlined management that virtual infrastructure brings.The migration procedure is rendered easy and smooth with the help of Parallels Transporter which can be invoked by following the Containers link on the Parallels Virtual Automation main menu or on the Parallels Virtual Automation dashboard and then clicking on the Migrate Server to Container icon.

Note: Although the Parallels Containers software allows you to migrate virtually any physical server running the Windows Server 2003/Windows Server 2008 or Linux operating system to a Container on your physical server, there are a number of limitations which should be taken into account before deciding on the migration process. To get detailed information on these limitations, please consult the Parallels Containers for Windows User's Guide.

Setting Up Connection to Physical Servers

The starting point of the migrating procedure with Parallels Transporter is establishing a connection to the physical server you wish to migrate.

To do this you need to specify the server IP address or hostname in the IP Address or Hostname field. The IP address and hostname should be the ones the server is recognized by on a network. After you have filled in the server coordinates, you have to provide the administrator's credentials (in the Administrator Name and Administrator Password fields) you use to log in to the migrating server. The default user name for the Linux-based server is root, the default user name for the Windows-based server is Administrator unless you have created a different user account. In

Managing Virtual Environments

this case you are expected to enter the user name you have adopted for a new user account. Mind that the new user must have the scope of rights the Linux root user or the Windows administrator is endowed with. Finally, specify the physical server that will host the target Container. If there is only one physical server that can host the Container, it will be filled in by default, and the field is grayed out.

Note: To secure a successful connection, the source physical server should have either of the following ports open: 4434 or 4435 for a physical server irrespective of its operating system, 445 port for Windows-based physical servers only, and port 22 for Linux-based physical server only.

After you have entered all the required information, click Connect to set up a connection to the server.

Reviewing Physical Server Configuration

In the second step Parallels Transporter allows you to check the configuration of the server you are going to migrate into a Container. This is necessary for you to verify that you are connected to exactly the same server you wish to migrate.

The information on the server is divided into three groups.

The Hardware Information table includes:

Name Description

Architecture The architecture of the server CPU(s).

CPU The number, name and power of the processor(s) installed on the physical server.

Operating Memory (Physical Memory on a Windows-based server)

Swap Memory The swap partition data: the total swap partition size, the swap memory used and the

The physical memory: the total physical memory available, the amount of the server physical memory used and the amount of free memory still remaining.

amount of the free swap memory.

The Network Information tells you the server hostname and the network interface details, such as the server IP address(es) and the network adapter type(s).

The Linux Disk Partitions section yields the following information:

Name Description

Name The name of the partition on the server disk.

Mounted The mount point of the partition described.

Type The file system type.

Block Size The block size of the partition file system.

Total Blocks The number of the blocks in the file system.

Used Blocks The number of the blocks used.

Free Blocks The number of the blocks still available for data storage.

Total Inodes The overall number of the inodes in the partition.

Managing Virtual Environments

Used Inodes The number of the inodes used.

Free Inodes The number of inodes free to use.

The Windows Disk Partitions section reads:

Name Description

Drive The name of the partition on the server disk.

Type The file system type.

Total Space The volume of the drive.

Used Space The space of the drive in use.

Free Space The space of the drive free to be used.

After you have reviewed the physical server system information, click Next to proceed to the customization of the server migration procedure or

configuring the target Container.

Customizing Migration Procedure

In the third step you have an opportunity to edit the details of the migration process. On this page you can tune your physical server migration by:

• indicating your Linux distribution in the Distribution Selection section before migrating a

physical server (the option is required). Parallels Transporter tries to identify the migrated server distribution automatically, but the potential danger here may be its failure to do so. This is likely to make it impossible to carry out certain post-migration operations on the Container into which the physical server has been migrated. Therefore, to cut out the risk, you must prompt the wizard your server distribution by selecting the corresponding name in the Select the Distribution drop-down menu.

• choosing a user/group quota partition to migrate. As a server administrator, you might have

already divided your hard disk into partitions to be used by different users/groups and set a corresponding quota for the usage thereof. Since all the file systems are copied to a single partition in the Container, your user/group quota parameters configuration may be lost. Therefore you are allowed to choose a partition you wish to save the quota values for and specify it in the Quota migration section. To do this, you have to select the partition name on the drop-down menu. Note that if you have more than one partition you have allocated for nonroot users, the quota parameters setup will be lost for the partitions other than the one you have indicated in this section. In this case you will need extra post-migration user/group, or second-level quota parameters setting up. You can learn more on the second-level quota configuration option in the Managing Disk Quotas section of the Parallels Virtuozzo Containers User's Guide.

Note: Although the partition migration with quotas proceeds smoothly in most cases, we recommend that you check all the partition quotas after the physical server migration and adjust them, if needed.

• excluding paths from copying them to the Container in the Exclude Paths section. This option

allows you to avoid migrating the data you do not need. You can single out such paths yourself or in some cases you will be prompted to do so by the relevant warning, advising you to exclude a certain path. The droppable path should be provided in the blank field in this section.
