8.2. Installing the Red Hat Enterprise Virtualization Hypervisor Packages

Summary
The Red Hat Enterprise Virtualization Hypervisor (v.6 x86_64) Red Hat Network channel contains the Hypervisor packages. The Hypervisor itself is contained in the rhev-hypervisor6 package. Additional tools supporting USB and PXE installations are also installed as a dependency. You must install the Hypervisor packages on the system that you intend to use to create Hypervisor boot media.

Procedure 8.1. Installing the Red Hat Enterprise Virtualization Hypervisor Packages

    • Subscribing to Download the Hypervisor using Certificate-Based RHN

      1. Identify Available Entitlement Pools

        To subscribe the system to Red Hat Enterprise Virtualization, you must locate the identifier for the relevant entitlement pool. Use the list action of the subscription-manager to find these:
        To identify available subscription pools for Red Hat Enterprise Virtualization, use the command:
        # subscription-manager list --available | grep -A8 "Red Hat Enterprise Virtualization"
      2. Attach Entitlement Pools to the System

        Using the pool identifiers located in the previous step, attach the Red Hat Enterprise Linux Server and Red Hat Enterprise Virtualization entitlements to the system. Use the attach parameter of the subscription-manager command, replacing [POOLID] with each of the pool identifiers:
        # subscription-manager attach --pool=[POOLID]
    • Subscribing to Download the Hypervisor using RHN Classic

      1. Log on to Red Hat Network (http://rhn.redhat.com).
      2. Move the mouse cursor over the Subscriptions link at the top of the page, and then click Registered Systems in the menu that appears.
      3. Select the system to which you are adding channels from the list presented on the screen, by clicking the name of the system.
      4. Click Alter Channel Subscriptions in the Subscribed Channels section of the screen.
      5. Select the Red Hat Enterprise Virtualization Hypervisor (v.6 x86_64) channel from the list presented on the screen, then click the Change Subscription button to finalize the change.
  1. Log in to the system on which the Red Hat Enterprise Virtualization Manager is installed. You must log in as the root user.
  2. Use yum to install rhev-hypervisor6:
    # yum install rhev-hypervisor6
  3. Use yum to install livecd-tools:
    # yum install livecd-tools
Result
The Hypervisor ISO image is installed into the /usr/share/rhev-hypervisor/ directory. The livecd-iso-to-disk and livecd-iso-to-pxeboot scripts are installed to the /usr/bin directory.

Note

Red Hat Enterprise Linux 6.2 and later allows more than one version of the ISO image to be installed at one time. As such, /usr/share/rhev-hypervisor/rhev-hypervisor.iso is now a symbolic link to a uniquely-named version of the Hypervisor ISO image, such as /usr/share/rhev-hypervisor/rhev-hypervisor-6.4-20130321.0.el6ev.iso. Different versions of the image can now be installed alongside each other, allowing administrators to run and maintain a cluster on a previous version of the Hypervisor while upgrading another cluster for testing.
Additionally, the symbolic link /usr/share/rhev-hypervisor/rhevh-latest-6.iso, is created. This links also targets the most recently installed version of the Red Hat Enterprise Virtualization ISO image.
