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)
• 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.
18
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.
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;
19
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.

Allow Dynamic Status
Selecting this check box enables the statuses of virtual environments to be updated
false to true.
Now, if you right-click any of the aforementioned items, you will see only the Parallels Virtual
Automation context menu.
Customizing User Profile
Defining Interface Settings
On the Interface Settings tab of the User Profile screen, you can set a number of parameters
related to the Parallels Virtual Automation interface.
You can access the User Profile section by clicking the login name in the upper part of the screen.
The options provided on the Interface Settings tab are grouped into three sections: Navigation
Settings, Regional Settings and Visual Settings.
Option Description
Home Page One of the ways to tweak Parallels Virtual Automation is to choose the first screen to be
loaded when you log in to Parallels Virtual Automation from the Home Page drop-down
menu.
Interface Language As Parallels Virtual Automation is localized into a number of languages, this drop-down menu
lets you choose the default interface language for Parallels Virtual Automation. This setting
affects the language of both your current Parallels Virtual Automation session and all future
sessions if User Default is chosen as the interface language on the Parallels Virtual
Automation login screen.
Local Time Zone This setting affects the date and time information found on such Parallels Virtual Automation
pages as Tasks Log, Alerts and Events. Choose the time zone you wish to be used when
viewing different kinds of logs.
GUI Elements Style You may set the Parallels Virtual Automation toolbar buttons to represent the operations
which can be performed by clicking them with only icons, or only text, or with both visual and
verbal elements.
Interface Skin Here you may choose a suitable interface colour for your Parallels Virtual Automation
affecting such elements as the Parallels Virtual Automation general layout (framed or nonframed), icons and images, and the colour palette.
Menu Details Level You can choose what items will be displayed under the Infrastructure and the Logical View
on the left Parallels Virtual Automation menu: folders, the physical servers distributed over
them, virtual environments - those that run on the physical servers, in the Infrastructure
sent to appropriate folders, in the Logical View.
Enable Tooltips Selecting or clearing this check box defines whether you will see short descriptions of the
elements of the Parallels Virtual Automation interface when pointing them with the cursor.
Show Top Right Buttons

Updates
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:
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.
23
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.
24
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.
25
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.
The Summary tab of the Infrastructure section provides you with general information of all the
physical servers and virtual environments. It allows you to quickly and timely assess the current
situation and, if necessary, take the required actions. The tab is available by clicking the
Infrastructure submenu in the Navigation tree.
The Overall Status section shows the virtual environments that have signaled resources
consumption alerts or those physical servers whose licenses have expired or are going to expire.
Note: You can configure Parallels Virtual Automation to not show alerts for specific mount points on your
system even if disk usage on them is close to or exceeds the set limit. For detailed information on how
you can do this, see Base Types and Interfaces > System Interface and Special Packets > system >
Calls > configuration in the PVA Agent XML API Reference guide.
Virtual Environment
The section displays information on all virtual environments registered in the PVA infrastructure.
Section Description
Status The column displays the number of running and stopped virtual environments. Upon clicking one
of the statuses, you are redirected to the Virtual Environments tab, with the virtual environments
grouped according to the chosen status.
OS The column displays types of operating systems running on virtual environments. Upon clicking an
OS name, you are redirected to the Virtual Environments tab, with the virtual environments
grouped according to the chosen OS.
• In the displayed table, select the check boxes of the physical servers you want to add to
Logical View, click Use Selected, and then click Save.
The chosen physical servers will be displayed on the Logical View main level.
If the Logical View level contains a folder and you want to add a virtual environment or a physical
server to the main level of this folder, go to the folder Summary tab and perform the
aforementioned operations.
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:
The IP address of the physical server used to connect to Master Server (the physical server
with the PVA Management Server component of Parallels Virtual Automation installed).
The name of the product the physical server is based on.
The virtualization solution used on the physical server.
The operating system installed on the physical server.
The name and version of the operating system installed on the physical server.
The microprocessor architecture of the physical server.
The percentage of the current CPU load on the physical server. Updated every 10 seconds.
The percentage of the current disk space usage of the physical server. Updated every 10
seconds.
The percentage of the current memory consumption of the physical server. Updated every
10 seconds.
The level of the physical server resources usage signaled by a corresponding alert.
The number of virtual environments which reside on the physical server and whose level of
the resources usage is signaled by a corresponding alert.
The current number of running virtual environments residing on the physical server.
The current number of stopped virtual environments residing on the physical server.
