Introduction
About Parallels Server Bare Metal 5.0
Parallels Server Bare Metal 5.0 is a virtualization solution that allows you to simultaneously run
multiple Parallels virtual machines and Containers on a single server. With Parallels Server Bare
Metal, you can efficiently use your server's hardware resources by sharing them among virtual
machines and Containers.
Parallels Server Bare Metal is installed directly on the server hardware and does not need any
operating system for its functioning. Once it is installed, Parallels Server Bare Metal allows you to
create virtual machines and Containers and manage them using the following tools:
• Parallels command-line interface (CLI). The command-line interface comprises a set of
Parallels command-line utilities that you can use to manage virtual machines and Containers,
both locally and remotely.
• Parallels Management Console. Parallels Management Console is a remote management tool
for Parallels Server Bare Metal with a graphical user interface. You can use this tool to manage
physical servers and Parallels virtual machines residing on them.
Note: In this version of Parallels Server Bare Metal, you cannot use Parallels Management Console to
create and manage Parallels Containers.
• Parallels Virtual Automation (PVA). Parallels Virtual Automation is a remote management tool
that allows you to manage physical servers and their virtual machines and Containers with the
help of a standard Web browser on any platform.
Graphically, a server with the Parallels Server Bare Metal software installed can be represented as
follows:

Creating Software RAIDs
A software RAID consists of two or more physical hard disks combined to act as a single logical
unit. Software RAIDs are created using special software and are meant for improving the disk
performance and providing fault tolerance from disk errors.
You can create software RAIDs when installing Parallels Server Bare Metal on your server. To do
this, select the Create custom layout radio button in the Partitioning window, and click Next. The
main partitioning window appears:
The process of creating software RAIDs is similar to that used to create software RAIDs in most
modern Linux distributions (e.g., Red Hat Enterprise Linux or CentOS) and includes the following
stages:
1 Making software RAID partitions.
2 Creating RAID arrays (or devices) from the newly made software RAID partitions.
44
Page 45
Installing Parallels Server Bare Metal 5.0
This section describes how to create a software RAID for the /vz partition when running the
Parallels Server Bare Metal installer in the graphical mode. However, you can easily adapt the
procedures shown here to create software RAIDs for other partitions (e.g., for the root partition) in
both the graphical and text modes.
Making software RAID partitions
In the first step, you need to create two or more identical software RAID partitions for the /vz
partition. These RAID partitions will then be used as the basis for making a RAID array.
To create a software RAID partition:
1 Click the Create button on the Please Select a Device screen.
45
Page 46
Installing Parallels Server Bare Metal 5.0
2 On the Create Storage screen, select the RAID Partition radio button, and click Create.
3 In the Allowable Drives section, select the check box of the drive you want to use for the
RAID. Make sure the check boxes of all the other drives are cleared. This is necessary because
a software RAID partition can be situated on one disk drive only.
4 In the Size field, specify the size for the /vz partition. The /vz partition is intended to store all
virtual machines and Containers data and should occupy as much disk space as possible.
5 Select Force to be a primary partition if you want to make the /vz partition a primary
partition.
6 Click OK. The newly created software RAID partition will appear in the main partitioning
window.
46
Page 47
Installing Parallels Server Bare Metal 5.0
Repeat the steps above to create other software RAID partitions for the /vz partition. Their number
can differ depending on the RAID configuration you want to implement. For example, if you are
going to deploy the RAID 1 configuration where 2 mirrored hard drives are used, you need to
create one more software RAID. Once you create it, your window should look like the following:
47
Page 48
Installing Parallels Server Bare Metal 5.0
Creating RAID devices
Now that you have created the necessary RAID partitions for the /vz partition, you can make a
RAID array on their basis. To do this:
1 On the Please Select a Device screen, click the Create button.
2 On the Create Storage screen, select the RAID Device radio button, and click Next.
3 In the Make RAID Device dialog, set the following parameters for the RAID device:
• Specify a mount point in the Mount Point field. In our case, the mount point should be /vz.
• Choose the filesystem type for the array in the File System Type field. ext3 is the
recommended filesystem type to use on servers running Parallels Server Bare Metal.
• Select a name for the RAID array in the RAID Device field. You can leave the name offered
by default or specify your own one.
• Choose the RAID level in the RAID Level field. For the /vz partition, you can choose any of
the RAID levels available in the drop-down menu.
• The RAID Members section lists all your software RAID partitions. Select the check boxes
next to the RAID partitions you created for the /vz partition.
• Specify the number of spare partitions in the Number of spares field. Spare partitions can
be configured in RAID 1 and RAID 5 implementations only.
48
Page 49
Installing Parallels Server Bare Metal 5.0
When you are done, click OK. The created RAID array appears in the Devices column under
RAID Devices.

Using Parallels Virtual Automation
Parallels Virtual Automation is a flexible and easy-to-use administration tool for managing servers
with Parallels Server Bare Metal and virtual machines and Containers residing on these servers.
Once you set up Parallels Virtual Automation, you can use it to connect to your Parallel servers with
a standard web browser on any platform. Parallels Virtual Automation includes the following
components:
• PVA Management Server (or Master Server or Management Node). This is a physical server
that ensures the communication between the server running Parallels Server Bare Metal (known
as Slave Server) and the Parallels Virtual Automation application. The Master Server keeps a
database with the information about all registered Slave Servers.
• Control Center. This is a front-end to the Parallels Virtual Automation application. You see
Control Center in the browser window when you log it to the Slave Server using Parallels Virtual
Automation.
• PVA Agent. This is a special agent installed on a Slave Server and ensuring the interaction
between the Slave Server, the Master Server, and your client computer (i.e. the computer you
use to connect to the Slave Server). Without this component, a server cannot be registered in
Management Server.
• Slave Server. This is a physical server running the Parallels Server Bare Metal software and
hosting a number of virtual machines and Containers. You use Control Center to log in to the
Slave Server and manage your virtual machines and Containers.
• Parallels Power Panel. This is a tool installed on the Slave Server and used for managing
particular virtual machines and Containers.
Graphically, a typical system with Parallels Virtual Automation can be represented as follows.
65
Page 66
Starting to Work in Parallels Server Bare Metal 5.0
66
Page 67
Starting to Work in Parallels Server Bare Metal 5.0
Setting Up Parallels Virtual Automation
Parallels Virtual Automation is automatically set up on your server during the Parallels Server Bare
Metal installation, provided you select the Install PVA Agent for Parallels Server and Install PVA
Management Node options in the Congratulations window of the Parallels Server Bare Metal
installer. During the setup procedure, the installer performs the following operations:
• Installs the PVA Agent component, including Parallels Power Panel, on the server. After that,
the server starts acting as the Slave Server.
• Creates a special Container on the server and installs the PVA Management Server and Control
Center components inside the Container. Once the Container is created and the components
are installed, the Container starts acting as the Master Server.
The last point needs further explanation. The PVA Management Server and Control Center
components cannot be installed directly on a server with Parallels Server Bare Metal. Instead, a
special Container is automatically created during the Parallels Server Bare Metal installation where
these components are installed. The Container is created with the following configuration:
• The Container is running the CentOS operating system.
• The amount of disk space inside the Container is set to 10 GB.
• The root account is automatically created inside the Container. The root password is
automatically set to that you specify during the Parallels Server Bare Metal installation for
logging in to the server.
• The Container can be accessed by the IP address and hostname you provide in the
Congratulations window of the Parallels Server Bare Metal installer.
• The Container uses the same DNS server you specify for the Parallels server during the Parallels
Server Bare Metal installation.
67
Page 68
Starting to Work in Parallels Server Bare Metal 5.0
Installing Parallels Virtual Automation Manually
During the Parallels Server Bare Metal installation, the Parallels Virtual Automation application is not
installed on the server in the following cases:
• You skipped the step of installing the license.
• Your license does not allow you to use Parallels Virtual Automation.
• You had no Internet connection when installing Parallels Server Bare Metal or the connection
got broken for some reason.
Later on, if you make up your mind to use Parallels Virtual Automation for managing Parallels
servers and their virtual machines and Containers, you can install this application manually by doing
the following:
1 Obtain the appropriate license from Parallels. This step is required only if your license does not
support using Parallels Virtual Automation.
2 Install the license on the server using Parallels Management Console or the vzlicload utility.
For information on installing licenses using these tools, see the Parallels Management Console
User's Guide and Parallels Server Bare Metal 5.0 User's Guide, respectively.
3 Once the license is installed, create the pva_opt.cfg file, open it for editing, and specify the
following options:
• PVA_AGENT=1 if you want to install the PVA Agent components or PVA_AGENT=0 if you do
not want to.
• PVA_MN=1 if you want to install the PVA Management Server and Control Center
components or PVA_MN=0 if you do not want to.
• PASSWD="XXXXXX" where XXXXXX is the password of the root user on the Parallels server
(you set this password during the Parallels Server Bare Metal installation). This option is
mandatory if you choose to install PVA Management Server and Control Center
components.
• PVA_IP="X.X.X.X" where X.X.X.X is the IP address to be assigned to the Management
Node. You will then use this IP address to log in to the Management Node. This option is
mandatory if you choose to install PVA Management Server and Control Center
components.
Note: The Management Node must be assigned a public IP address to download the installation files
from the Parallels remote repository. Using alternative (local) repositories for downloading the
Management Node installation files is also supported but via kickstart files only. For more information,
see the Installation via PXE document.
• PVA_HOSTNAME="hostname" where hostname is the hostname to be assigned to the
Management Node. This option is mandatory if you choose to install PVA Management
Server and Control Center components
4 Make sure the Parallels server is connected to the Internet.
68
Page 69

5 In a terminal, change to the directory where the pva_opt.cfg file is located, and run this
command:
# /usr/libexec/pva-setup.sh --install pva_opt.cfg
Connecting to a Server
To connect to a server using Parallels Virtual Automation, do the following:
1 On any computer, open your favorite web browser.
2 Make sure that the computer can access the server with Parallels Server Bare Metal over the
network.
3 Type the IP address or hostname of the Container acting as the Master Server in the browser
window (e.g. http://123.124.125.126).
4 Use the root credentials to log in to the Container (i.e. the root user name and the password
you entered during the Parallels Server Bare Metal installation).
Note: For more information on using Parallels Virtual Automation for managing servers with Parallels

Private area. A part of the file system storing Container files that are not shared with other
Containers.
Template (package set). A set of original application files (packages) repackaged for mounting
over Virtuozzo File System. There are two types of templates. OS Templates are used to create
new Containers with a pre-installed operating system. Application templates are used to install an
application or a set of applications in Containers.
UBC. An abbreviation of User Beancounter.
User Beancounter. The subsystem of the Parallels Server Bare Metal software for managing
Container memory and some system-related resources.
Virtual Environment (VE). An obsolete designation of a Container.
Virtuozzo File System (VZFS). A virtual file system for mounting to Container private areas. VZFS
symlinks are seen as real files inside Containers.
Virtual machine (VM). A computer emulated by Parallels Server Bare Metal. Like a Container, a
virtual machine is functionally identical to an isolated standalone computer, with its own IP
addresses, processes, files, its own users database, its own configuration files, its own
applications, system libraries, and so on. However, as distinct from Containers, virtual machines
run their own operating systems rather than sharing one operating system kernel.
