PrefaceThe Red Hat Enterprise Virtualization platform is a richly featured virtualization management solution

providing fully integrated management across virtual machines. It is based on the leading open source

virtualization platform and provides superior technical capabilities. The platform offers scalability in the

management of large numbers of virtual machines.

1. About this GuideThis guide describes how to install the Red Hat Enterprise Virtualization platform.

1.1. The Red Hat Enterprise Virtualization Documentation SuiteThe Red Hat Enterprise Virtualization documentation suite provides information on installation,

development of applications, configuration and usage of the Red Hat Enterprise Virtualization platform

and its related products.

The Red Hat Enterprise Virtualization documentation suite

Red Hat Enterprise Virtualization Hypervisor Release Notes contain release specific information for

Red Hat Enterprise Virtualization Hypervisors.

Red Hat Enterprise Virtualization Manager Release Notes contain release specific information for

Red Hat Enterprise Virtualization Managers.

Red Hat Enterprise Virtualization for Servers Installation Guide (the book you are reading) describes

the installation prerequisites and procedures. Read this if you need to install Red Hat Enterprise

Virtualization for Servers. The installation of hosts, manager and storage are covered in this guide.

You will need to refer to the Red Hat Enterprise Virtualization for Servers Administration Guide to

configure the system before you can start using the platform.

Red Hat Enterprise Virtualization for Servers Administration Guide describes how to setup,

configure and manage Red Hat Enterprise Virtualization for Servers. It assumes that you have

successfully installed the Red Hat Enterprise Virtualization manager and hosts.

Red Hat Enterprise Virtualization Hypervisor Deployment Guide describes how to deploy and install

the hypervisor. Read this guide if you need advanced information about installing and deploying

Hypervisors. The basic installation of Hypervisor hosts is also described in the Red Hat Enterprise

Virtualization for Servers Installation Guide

Red Hat Enterprise Virtualization Manager API Guide describes how to use the command line

functions to set up and manage virtualization tasks. Use this guide if you do not wish to use thegraphical user interface, and prefer using the command line.

1.2. AudienceThis documentation suite is intended for system administrators installing a virtual environment

based on the specifications provided to them by their solution architect. An advanced level of system

administration, preferably including familiarity with virtual machine data center operations, is assumed.

This document is not intended for beginners.

2. Document ConventionsThis manual uses several conventions to highlight certain words and phrases and draw attention to

specific pieces of information.


6/88

Preface

vi

In PDF and paper editions, this manual uses typefaces drawn from the Liberation Fonts1

set. The

Liberation Fonts set is also used in HTML editions if the set is installed on your system. If not,

alternative but equivalent typefaces are displayed. Note: Red Hat Enterprise Linux 5 and later includes

the Liberation Fonts set by default.

2.1. Typographic ConventionsFour typographic conventions are used to call attention to specific words and phrases. These

conventions, and the circumstances they apply to, are as follows.

Mono-spaced Bold

Used to highlight system input, including shell commands, file names and paths. Also used to highlight

keycaps and key combinations. For example:

To see the contents of the file my_next_bestselling_novel in your current

working directory, enter the cat my_next_bestselling_novel command at the

shell prompt and press Enter to execute the command.

The above includes a file name, a shell command and a keycap, all presented in mono-spaced bold

and all distinguishable thanks to context.

Key combinations can be distinguished from keycaps by the hyphen connecting each part of a key

combination. For example:

Press Enter to execute the command.

Press Ctrl+Alt+F2 to switch to the first virtual terminal. Press Ctrl+Alt+F1 to

return to your X-Windows session.

The first paragraph highlights the particular keycap to press. The second highlights two keycombinations (each a set of three keycaps with each set pressed simultaneously).

If source code is discussed, class names, methods, functions, variable names and returned values

mentioned within a paragraph will be presented as above, in mono-spaced bold. For example:

File-related classes include filesystem for file systems, file for files, and dir for

directories. Each class has its own associated set of permissions.

Proportional Bold

This denotes words or phrases encountered on a system, including application names; dialog box text;

labeled buttons; check-box and radio button labels; menu titles and sub-menu titles. For example:

Choose System PreferencesMouse from the main menu bar to launch Mouse

Preferences. In the Buttons tab, click the Left-handed mouse check box and click

Close to switch the primary mouse button from the left to the right (making the mouse

suitable for use in the left hand).

To insert a special character into a gedit file, choose Applications Accessories

Character Map from the main menu bar. Next, choose Search Find from the

Character Map menu bar, type the name of the character in the Search field and click

Next. The character you sought will be highlighted in the Character Table. Double-

Pull-quote Conventions

vii

click this highlighted character to place it in the Text to copy field and then click the

Copy button. Now switch back to your document and choose Edit Paste from the

gedit menu bar.

The above text includes application names; system-wide menu names and items; application-specific

menu names; and buttons and text found within a GUI interface, all presented in proportional bold andall distinguishable by context.

Mono-spaced Bold Italic or Proportional Bold Italic

Whether mono-spaced bold or proportional bold, the addition of italics indicates replaceable or

variable text. Italics denotes text you do not input literally or displayed text that changes depending on

circumstance. For example:

To connect to a remote machine using ssh, type ssh [email protected] at

a shell prompt. If the remote machine is example.com and your username on that

machine is john, type ssh [email protected].

The mount -o remount file-system command remounts the named file

system. For example, to remount the /home file system, the command is mount -o

remount /home.

To see the version of a currently installed package, use the rpm -qpackage

command. It will return a result as follows:package-version-release.

Note the words in bold italics above username, domain.name, file-system, package, version and

release. Each word is a placeholder, either for text you enter when issuing a command or for text

displayed by the system.

Aside from standard usage for presenting the title of a work, italics denotes the first use of a new and

important term. For example:

Publican is a DocBookpublishing system.

2.2. Pull-quote ConventionsTerminal output and source code listings are set off visually from the surrounding text.

Output sent to a terminal is set in mono-spaced roman and presented thus:

books Desktop documentation drafts mss photos stuff svn

books_tests Desktop1 downloads images notes scripts svgs

Source-code listings are also set in mono-spaced roman but add syntax highlighting as follows:

package org.jboss.book.jca.ex1;

import javax.naming.InitialContext;

publicclass ExClient

{

publicstaticvoidmain(String args[])

throws Exception

{

InitialContext iniCtx = new InitialContext();Object ref = iniCtx.lookup("EchoBean");

EchoHome home = (EchoHome) ref;

Echo echo = home.create();


8/88

Preface

viii

System.out.println("Created Echo");

System.out.println("Echo.echo('Hello') = " + echo.echo("Hello"));

}

}

2.3. Notes and WarningsFinally, we use three visual styles to draw attention to information that might otherwise be overlooked.

Note

Notes are tips, shortcuts or alternative approaches to the task at hand. Ignoring a note should

have no negative consequences, but you might miss out on a trick that makes your life easier.

Important

Important boxes detail things that are easily missed: configuration changes that only apply to

the current session, or services that need restarting before an update will apply. Ignoring a box

labeled 'Important' will not cause data loss but may cause irritation and frustration.

Warning

Warnings should not be ignored. Ignoring warnings will most likely cause data loss.

3. We Need Feedback!If you find a typographical error in this manual, or if you have thought of a way to make this manual

better, we would love to hear from you! Please submit a report by email to the author of the manual,

Susan Burgess ([email protected] ). When submitting a bug report, be sure to mention the

manual's identifier: Server_Install_Guide.

OverviewThis document describes how to install the Red Hat Enterprise Virtualization platform for the first time.

It contains information on hardware and software prerequisites, installation procedures and initial

configuration.

1.1. System architectureThe Red Hat Enterprise Virtualization platform consists of:

Red Hat Enterprise Virtualization Manager acts as a centralized management system that allows

system administrators to view and manage virtual machines and images. The Red Hat Enterprise

Virtualization Manager provides a comprehensive range of features including search capabilities,

resource management, live migrations and provisioning.

The Red Hat Enterprise Virtualization Manager is able to manage hosts running Red Hat Enterprise

Virtualization Hypervisor and Red Hat Enterprise Linux 5.5 or newer.

Red Hat Enterprise Virtualization Hypervisor is a thin virtualization layer deployed across the

server infrastructure. It is based on Kernel-based Virtual Machine (KVM), which is a core component

of the Linux kernel.

The Red Hat Enterprise Virtualization Hypervisor is a stand-alone Red Hat Enterprise Linux

installation developed specifically for use with Red Hat Enterprise Virtualization. It is also possible

to configure Red Hat Enterprise Linux 5.5 or newer to be used as a host. Red Hat Enterprise Linux

hosts can be used concurrently with Red Hat Enterprise Virtualization Hypervisors.

The descriptions in this guide provide sufficient knowledge for performing a basic installation of the

system. For a more thorough description, refer to the Red Hat Enterprise Virtualization for ServersAdministration Guide.

1.2. How the management system worksThe following components combine to enable system administrators to setup, configure and maintain

the virtualized environment by using a graphical interface.

1.2.1. About the serversThe Red Hat Enterprise Virtualization platform consists of one or more Hypervisors (or hosts) and at

least one Manager. The virtual machines (or guests) are hosted on the Hypervisor. The system and all

of its components are managed through Red Hat Enterprise Virtualization Manager.

Red Hat Enterprise Virtualization Manager provides a graphical user interface to administer the

physical and logical resources within the virtual environment infrastructure. It can be used to manage

provisioning, connection protocols, user sessions, virtual machine pools, images and high availability/

clustering. The Red Hat Enterprise Virtualization Manager runs on Windows 2008 server in clustered

mode, with active-standby configuration.

Red Hat Enterprise Virtualization Hypervisor or Red Hat Enterprise Linux Host runs the virtualmachines on Red Hat Enterprise Linux with KVM virtualization technology. It also includes a resource

optimization layer that allows for improved virtual machine interactivity and management.

1.2.2. About the virtual machinesRed Hat Enterprise Virtualization enables a thin client or personal computer to access virtual machines

with minimal local resources, using a standard web browser.

The following operating systems are currently supported on virtual machines:

Red Hat Enterprise Linux 3 (32 bit and 64 bit)




Windows XP Service Pack 3 and newer (32 bit only)

Windows Server 2003 Service Pack 2 and newer (32 bit and 64 bit)

Windows Server 2008 (32 bit and 64 bit)

Windows Server 2008 R2 (64 bit only)

Windows 7 (32 bit and 64 bit)

1.3. About the installation processRed Hat Enterprise Virtualization is installed using the following steps:

1. Check that you have the necessary prerequisites, hardware and software specified in Chapter 2,

System Requirements.

2. Install the Red Hat Enterprise Virtualization Manager according to Chapter 3, Installing the Red

System RequirementsThis section describes the basic hardware and software prerequisites required for installing the Red

Hat Enterprise Virtualization platform.

It is assumed that the requirements for your specific implementation of the Red Hat EnterpriseVirtualization system have been defined by your solution architect. Therefore, the solution planning

stage is not covered by this document. However, be aware that the following must be considered

when designing the system: total number of virtual machines to be used, storage requirements,

network capacity, total CPU and memory requirements. Additional notes regarding system planning

are provided inAppendix A, Planning the System Architecture.

Ensure that the listed requirements are ready before attempting installation.

2.1. Prerequisites

Latest Red Hat Enterprise Virtualization Manager Release Notes.

A client with Windows XP and .NET Framework 3.1 with Service Pack 1, or Windows 7, is required

to access the web-based administration portal. The client must be running Internet Explorer 7 or 8.

To connect to virtual machines with SPICE via the Red Hat Enterprise Virtualization administration

portal, a SPICE browser plugin is used. The SPICE plugin for Internet Explorer is only compatible

with 32-bit editions of Internet Explorer. When using a 64-bit Windows operating system, you must

install a 32-bit edition of Internet Explorer to use the SPICE plugin. You must also make a global

registry setting change to allow the WPF application to run as a 32-bit process. The process for

making this change is described in Microsoft kbase article 9743961

2.2. Hardware requirements One or more physical servers to act as the Red Hat Enterprise Virtualization Hypervisors or Red Hat

Enterprise Linux Hosts, each with:

Hardware virtualization support:

a. AMD system with AMD-V enabled in the BIOS and AMD64 CPU extension; or

b. Intel system with Intel VT enabled in the BIOS and Intel 64 CPU extensions.

Minimum 512MB of RAM.

Minimum 512MB of additional RAM for each virtual machine. The amount of RAM allocated to

each virtual machine is dependent on the guest operating system.

Minimum 750MB storage for installation of the Hypervisor on hard disk drive, plus additional

storage for swap. Refer to Red Hat Knowledgebase2

for more information on recommended swap

sizes.

Ensure that all Hypervisor or host servers to be used within a single cluster have the same CPU

type. This enables virtual machines to reside on any host within the cluster and to be migrated

between hosts. For further information, refer to the Red Hat Enterprise Virtualization for Servers

Administration Guide.

One server to act as the Red Hat Enterprise Virtualization Manager, with:

Minimum 1 GB of memory.

Installing the Red Hat Enterprise

Virtualization HypervisorThis chapter covers installing and integrating Red Hat Enterprise Virtualization Hypervisors with a Red

Hat Enterprise Virtualization Manager.

The Red Hat Enterprise Virtualization Hypervisor mustbe installed on a physical server and cannot

be installed on a virtual machine.

The installation process will reconfigure the selected storage device and destroy all data. Therefore,

ensure that any data to be retained is successfully backed up before proceeding.

The following method can be used when installing multiple servers. However, ensure that unique

hostnames and IP addresses are used for each Hypervisor installation, in order to avoid network

conflicts.

The following procedure provides installation instructions for using a CD-ROM created using theRed Hat Enterprise Virtualization Hypervisor ISO image available from Red Hat. For alternative

installation methods using USB Flash Drive or Network (PXE) Boot, refer to the Red Hat Enterprise

Virtualization Hypervisor Deployment Guide available at http://www.redhat.com/docs/.

Red Hat Enterprise Virtualization Hypervisors can use Storage Attached Networks (SANs) and other

network storage for storing virtualized guest images. However, a local storage device is required for

installing and booting the Hypervisor.

Automated Installations

Red Hat Enterprise Virtualization Hypervisor installations can be automated or conducted withoutinteraction. This type of installation is only recommended for advanced users. Refer to the Red

Hat Enterprise Virtualization Hypervisor Deployment Guide for more information.

4.1. Preparing an installation discRed Hat Enterprise Virtualization Hypervisors can be installed using an optical disc on systems with a

functional CD-ROM or DVD drive.

These procedures require a Red Hat Enterprise Linux 5 or higher system with RHN entitlements for

the Red Hat Enterprise Virtualization channels.

Note

Access to a working system with an optical recorder drive and optical disk recording software

is required for creation of the installation disc. The instructions in this guide use the cdrecord

package, which is installed by default on Red Hat Enterprise Linux.

Procedure 4.1. Confirm recording software is present on Red Hat Enterprise Linux

1. To verify that the cdrecord package is present on the system, perform a query using the rpm

package manager by entering the command:

# rpm -q cdrecord
http://www.redhat.com/docs/


36/88

Chapter 4. Installing the Red Hat Enterprise Virtualization Hypervisor

28

2. If the cdrecord package is installed, the package name will be displayed in the system

output.

If notification is displayed that the cdrecord package is not installed, it can be installed using

the command:

# yum install cdrecord

Once the cdrecord package is verified as being present, the installation media can be created.

Procedure 4.2. Create an installation disc

1. Enable the Red Hat Enterprise Virtualization Hypervisor 5 channel on RHN.

2. Install the Red Hat Enterprise Virtualization Hypervisor ISO image package.

# yum -y install rhev-hypervisor

Alternatively, download the Red Hat Enterprise Virtualization Hypervisor CD-ROM image from

Red Hat Network1.

3. Insert a blank CD-ROM or DVD into your CD/DVD recorder drive.

4. Record the ISO file to disc using the cdrecord command in the format:

# cdrecord dev=device[iso file path]

For example, if using the first CD-RW device (/dev/cdrw) available and the Hypervisor ISO file

located at /usr/share/rhev-hypervisor/rhev-hypervisor.iso the command used is:

# cdrecord dev=/dev/cdrw /usr/share/rhev-hypervisor/rhev-hypervisor.iso

5. If an error occurs during the recording process, try inserting a new writable disc and repeat the

previous command.

Once the record process has completed without any errors occurring, the installation media is

ready to use. The Red Hat Enterprise Virtualization Hypervisor uses the isomd5sum to verify the

integrity of the installation media each time the Hypervisor is booted. If media errors are reported

during the boot sequence, a new installation disc will need to be created.

4.2. Confirm hardware virtualization supportIf unsure, verify that the virtualization extensions are present and enabled in the BIOS before installing

the Hypervisor.

1. Insert the Red Hat Enterprise Virtualization Hypervisor installation CD-ROM into the CD-ROM

drive of the server.

2. Power on the system and ensure it boots from the CD.

3. Once the Hypervisor has completed the boot phase and the boot prompt is displayed, enter the

command:

: linux rescue
https://rhn.redhat.com/network/software/channels/details.pxt?cid=9462


37/88

Boot the Hypervisor

29

4. To verify that your CPU contains the virtualization extensions, enter the command:

# grep -E 'svm|vmx' /proc/cpuinfo

The processor is hardware virtualization capable if output is displayed.

5. To verify that the virtualization extensions are enabled in the BIOS, check that the kvm modules

are loaded in the kernel by entering:

# lsmod | grep kvm

If the output includes kvm_intel or kvm_amd then the kvm hardware virtualization modules are

loaded and the system meets requirements.

Note

If hardware virtualization support is not present and enabled, it is not possible to install the RedHat Enterprise Virtualization Hypervisor.

4.3. Boot the Hypervisor

1. Insert the Red Hat Enterprise Virtualization Hypervisor installation CD-ROM into the CD-ROM

drive of the server.

2. Power on the system and ensure the system boots from CD.

3. Once the Hypervisor has completed the boot phase and the boot prompt is displayed, press

Enter to continue.

If the Hypervisor has been previously installed, you may need to provide additional parameters to

cause the server to boot to the configuration setup menu. For further information, refer to the Red

Hat Enterprise Virtualization Hypervisor Deployment Guide.

4.4. The Red Hat Enterprise Virtualization Hypervisor

Configuration MenuOnce the Red Hat Enterprise Virtualization Hypervisor boots you will see the Hypervisor Configuration

Menu.

The Hypervisor Configuration Menu is an interactive tool for installing Red Hat Enterprise Virtualization

Hypervisors. The Hypervisor Configuration Menu resembles Example 4.1, Red Hat Enterprise

Virtualization Hypervisor Configuration Menu. Throughout this chapter it will be referred to as the

main menu.

4.5. Remove existing Red Hat Enterprise Virtualization

Hypervisor installationsIf the Hypervisor was previously installed on the local system, remove the existing installation by

selecting the Support Menu option from the main menu, then selecting Uninstall an existing

Hypervisor.

On systems with existing Hypervisors

On systems that have a Red Hat Enterprise Virtualization Hypervisor installed and some

systems with LVM volumes, the firstboot parameter may be required to trigger the interactive

installation. To use the firstboot parameter, append it to other kernel parameters. On a

system with an existing Red Hat Enterprise Virtualization Hypervisor use the following kernel

parameters to activate the interactive installation:

: linux firstboot

For further information on removing previous versions of the Red Hat Enterprise Virtualization

Hypervisor, refer to the Red Hat Enterprise Virtualization Hypervisor Deployment Guide.

Partitioning the disk

31

4.6. Partitioning the diskThe partitions used by the Red Hat Enterprise Virtualization Hypervisor are configured from this menu.

For most installations the default partition layout is optimal.

Warning

Running this procedure will destroy all data on the local storage device selected with the

storage_init parameter.

Procedure 4.3. The Storage Configuration menu

1. Select the Configure storage partitions option from the main menu to open the Configure

storage partitions menu.

Example 4.2. The Configure storage partitions menu

Configure storage partitions

1) Configure

2) Review

3) Commit configuration

4) Return to the Hypervisor Configuration Menu

Choose an option:

2. Choose partition sizes

Select Configure.

You are prompted to set the size of boot, swap, root, config, logging and data partitions. The value

is accepted in megabytes (MB).

Setting a size value of -1 sets the partition to take up all remaining disk space. Note that this can

only be used with the Data partition.

Pressing Enter without any value sets the partition to the default size.

Important

Do not append units onto the end of the partition size values. Using MB or similar unit on theend of a value may have adverse effects. For example, use the value 5 instead of 5MB.

a. The boot partition contains the boot loader, kernel and initramfs.

The default and only supported size for the boot partition is 50MB.

b. The swap partition is used for swapping underused memory to the hard drive to speed up

memory performance. The default size of the swap partition is calculated from amount of

RAM and overcommit ratio (default is 0.5). Red Hat Enterprise Virtualization Hypervisors

must have a swap partition and the swap partition cannot be disabled by setting its size to 0.

The minimum size for the swap partition is 5MB.

Red Hat Knowledgebase2

has an article on determining the size of the swap partition.
http://kbase.redhat.com/faq/docs/DOC-15252


40/88


32

Use the formula from the Red Hat Knowledgebase and add storage for the overcommit ratio

(RAM multiplied by the overcommit ratio).

Recommended swap + (RAM * overcommit) = swap partition size

Pressing Enter during the installation sequence sets a recommended value for the swappartition.

c. The root partition contains the core files for the Hypervisor and the LiveOS directory from

the installation media. The default total size of the root file system partitions is 512MB. That

is broken up into 256MB for one root partition and an additional 256MB for a backup root

partition.

The default and only supported size for the root partition is 256MB. The size entered is per

partition, with the total size of the root partitions double what is entered.

d. The config partition stores configuration files for the Hypervisor.

The default and minimum size for the configuration partition is 5MB.

e. The logging partition stores all logs for the Hypervisor.

The default size for the logging partition is 2048MB, the minimum size is 256MB.

f. The data partition stores core files and kdump files and acts as temporary storage for ISO

files. The default size of the data partition is the remaining available disk space (labeled as

-1).

When ISO files are uploaded using the ISO Uploader tool, they are temporarily stored on the

data partition of a Red Hat Enterprise Virtualization Hypervisor host, before being moved to

the shared ISO Library. The data partition must include sufficient space to store these ISO

files, which can be over 4GB in size for modern operating systems.

The data partition must be large enough to hold core files for kvm. Core files depend on the

RAM size for the guests. The data partition must also be large enough to store kernel dump

files, also known as kdumps. A kdump file is usually the same size the host's system RAM.

The data partition also stores the Red Hat Enterprise Virtualization Hypervisor ISO file for

Red Hat Enterprise Virtualization Hypervisor upgrades.

The data partition should be at least 1.5x as large as the RAM on the host system plus an

additional 512MB in size. The minimum size is 256MB.

3. Review

Select the Review menu option. The review menu output similar to the screenshot below:

The local disk will be repartitioned as follows:

================================================

Physical Hard Disk: /dev/hda (1024 MB)

Optionally: append a port after the hostname or IP address

For example, 10.0.0.1:443 or rhev.example.com:443

a. Enter the Red Hat Enterprise Virtualization Manager's hostname or IP address in the

specified format.

If the Red Hat Enterprise Virtualization Manager port is skipped the setup will use the default

port, port 443. However, if a port has previously been assigned, the Red Hat Enterprise

Virtualization Hypervisor uses that port as the default instead. For example, if port 12345

was specified during a previous installation then the default port for future installations is port

12345.

Using other ports

Red Hat Enterprise Virtualization Managers use 443 by default. If you configured

another port when installing the Red Hat Enterprise Virtualization Manager write it down.

Once another port is specified for the Red Hat Enterprise Virtualization Hypervisor it will

be recorded as the new "default".

b. If the Red Hat Enterprise Virtualization Manager is successfully located, the following output

Contains general messages from the system and core services.

/var/log/secure

Contains authentication and security messages, including failed login attempts.

4.13. InstallationOnce all the previous steps are complete, the Red Hat Enterprise Virtualization Hypervisor can be

installed to the local storage device.

Storage, networking and the Red Hat Enterprise Virtualization Manager mustbe configured before

continuing.

1. Select Install locally and reboot from the Hypervisor Configuration Menu.

2.This option exits the menu and requires a reboot.

Ensure local storage and networking is configured

correctly on the previous menu before continuing.

The current kernel boot parameters are

crashkernel=128M@16M elevator=deadline processor.max_cstate=1

Enter additional kernel boot parameters (press Enter to use the present arguments):

Press Enter to continue.

3.Do you wish to proceed ([Y]es or [N]o)?

Press Y to continue.

The final installation sequence begins. Once the installation is complete the Red Hat Enterprise

Virtualization Hypervisor will reboot.

After rebooting, the Red Hat Enterprise Virtualization Hypervisor is installed and integrated with Red

Hat Enterprise Virtualization Manager for Servers. You should have a new host available in the Red

Hat Enterprise Virtualization Manager interface.

Note

You may need to remove the boot media and change the boot device order to prevent the

installation sequence restarting after the system reboots.

4.14. Using the hypervisorOnce the Hypervisor has finished rebooting, it is automatically registered with the Red Hat Enterprise

Virtualization platform. The Red Hat Enterprise Virtualization Manager interface displays the

Hypervisor under the Hosts tab. To prepare the Hypervisor for use, it must be approved using Red Hat

Enterprise Virtualization Manager.

Procedure 4.5. Approve the Hypervisor

1. Login to the Red Hat Enterprise Virtualization Manager admin portal (refer to Section 3.2.11,

Login to the administrator portal).

Using Red Hat Enterprise Linux HostsVirtual machines on Red Hat Enterprise Linux can be managed by Red Hat Enterprise Virtualization

Manager. Red Hat Enterprise Linux hosts can be used concurrently with Red Hat Enterprise

Virtualization Hypervisors.

Important

Only the AMD64/Intel 64 version of Red Hat Enterprise Linux is compatible for use with Red Hat

Enterprise Virtualization.

5.1. Adding Red Hat Enterprise Linux HostsRed Hat Enterprise Virtualization also supports hosts running Red Hat Enterprise Linux 5.5 AMD64/

Intel 64 version. This section describes the preparatory steps for installing the Red Hat EnterpriseLinux host, as well as the steps to manually add the host to the Red Hat Enterprise Virtualization

platform.

Adding a host can take some time, as the following steps are completed by the platform: virtualization

checks, installation of packages, creation of bridge and a reboot of the host. Use the Details pane to

monitor the hand-shake process as the host and management system establish a connection.

Note

Red Hat Enterprise Linux 5.4 hosts can only be used with a Red Hat Enterprise Virtualization

Manager which was upgraded from version 2.1 to 2.2. They can only be attached to data centers

running in version 2.1 compatibility mode. New installations of Red Hat Enterprise Virtualization

Manager 2.2 or data centers running in version 2.2 compatibility mode can only support Red

Hat Enterprise Linux 5.5 hosts. Red Hat Enterprise Virtualization Manager 2.2 in version 2.1

compatibility mode can support Red Hat Enterprise Linux 5.5 hosts.

The following table shows which versions of Red Hat Enterprise Linux are supported as hosts for each

version of Red Hat Enterprise Virtualization.

5.1.1. Preparing Red Hat Enterprise Linux HostsTo ensure a smooth and successful integration of Red Hat Enterprise Linux Hosts and Red Hat

Enterprise Virtualization platform, prepare the host carefully according to the instructions in this

section.

Ensure that Red Hat Enterprise Linux 5.5 is correctly installed and configured on the physical host.

Refer to the Red Hat Enterprise Linux Installation Guide for more information.

Only the Base package group is required. All other packages can be removed or not selected.

Important note on fresh installations

Do not select the Virtualization or KVM package groups when installing Red Hat Enterprise

Linux, as they contain packages that are not compatible for use with Red Hat Enterprise

Virtualization.

Ensure that VLANs are configured for access to the Red Hat Enterprise Virtualization Manager.

Ensure the host is correctly subscribed to the appropriate Red Hat Network channels.

Red Hat Enterprise Virt Management Agent (v.5 for x86_64)

RHEL Virtualization (v. 5 for 64-bit x86_64)

Note

If you do not have the appropriate subscription entitlements, contact Red Hat Customer

Service.

Install the fence-agents, kvm-qemu-imgbridge-utils packages required by Red Hat

Enterprise Virtualization Manager to manage Red Hat Enterprise Linux hosts. During installation if

the required additional packages are not found, they will be automatically installed by the Red Hat

Enterprise Virtualization Manager.

Install the required packages with yum:

# yum install bridge-utils fence-agents kvm-qemu-img

Warning

If you are using proprietary directory services or standard directory services with no access

to authentication files for user management, the vdsm package will fail to create the required

system user . The authentication files required by the useradd command must be accessible

to the installer. Red Hat Directory Server (RHDS) recommends a security policy with a mixture

of local files and LDAP. Following this recommendation will resolve this issue.

Uninstall incompatible packages.
