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
Identify Available Entitlement Pools
To subscribe the system to Red Hat Enterprise Virtualization, you must locate the identifier for the relevant entitlement pool. Use thelistaction of thesubscription-managerto find these:To identify available subscription pools forRed Hat Enterprise Virtualization, use the command:# subscription-manager list --available | grep -A8 "Red Hat Enterprise Virtualization"
Attach Entitlement Pools to the System
Using the pool identifiers located in the previous step, attach theRed Hat Enterprise Linux ServerandRed Hat Enterprise Virtualizationentitlements to the system. Use theattachparameter of thesubscription-managercommand, replacing [POOLID] with each of the pool identifiers:# subscription-manager attach --pool=[POOLID]
Subscribing to Download the Hypervisor using RHN Classic
- Log on to Red Hat Network (http://rhn.redhat.com).

rootuser. - Use
yumto install rhev-hypervisor6:# yum install rhev-hypervisor6
- Use
yumto 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.
