5.2. Installing KVM packages on an existing Red Hat Enterprise Linux system

The section describes the steps for installing the KVM hypervisor on a working Red Hat Enterprise Linux 6 or newer system.
Adding packages to your list of Red Hat Network entitlements
This section describes how to enable Red Hat Network (RHN) entitlements for the virtualization packages. You need these entitlements enabled to install and update the virtualization packages on Red Hat Enterprise Linux. You require a valid Red Hat Network account in order to install virtualization packages on Red Hat Enterprise Linux.
In addition, your machines must be registered with RHN. To register an unregistered installation of Red Hat Enterprise Linux, run the rhn_register command and follow the prompts.
If you do not have a valid Red Hat subscription, visit the Red Hat online store.
Procedure 5.1. Adding the Virtualization entitlement with RHN
  1. Log in to RHN using your RHN username and password.
  2. Select the systems you want to install virtualization on.
  3. In the System Properties section the present systems entitlements are listed next to the Entitlements header. Use the (Edit These Properties) link to change your entitlements.
  4. Select the Virtualization checkbox.
Your system is now entitled to receive the virtualization packages. The next section covers installing these packages.
Installing the KVM hypervisor with yum
To use virtualization on Red Hat Enterprise Linux you require the kvm package. The kvm package contains the KVM kernel module providing the KVM hypervisor on the default Red Hat Enterprise Linux kernel.
To install the kvm package, run:
# yum install kvm
Now, install additional virtualization management packages.
Install the other recommended virtualization packages:
# yum install virt-manager libvirt libvirt-python python-virtinst libvirt-client
