The section describes the steps necessary to install the virtualization packages on a working Red Hat Enterprise Linux system.
Registering your system with the subscription-manager command

Your machines must be registered on your Red Hat account to receive packages and updates. To register an unregistered installation of Red Hat Enterprise Linux, run the subscription-manager register command and follow the prompts.

If you do not have a valid Red Hat subscription, visit the Red Hat online store.
Installing the Xen hypervisor with yum

To use virtualization on Red Hat Enterprise Linux you need the xen and kernel-xen packages. The xen package contains the hypervisor and basic virtualization tools. The kernel-xen package contains a modified Linux kernel which runs as a virtual machine guest on the hypervisor.

To install the xen and kernel-xen packages, run:
# yum install xen kernel-xen
Additional virtualization packages are available for management and configuration.
Install the other recommended virtualization packages:
# yum install virt-manager libvirt libvirt-python python-virtinst
