What is Xen?
The Xen hypervisor, the powerful open source industry standard for virtualization, offers a powerful, efficient, and secure feature set for virtualization of x86, x86_64, IA64, ARM, and other CPU architectures. It supports a wide range of guest operating systems including Windows, Linux, Solaris, and various versions of the BSD operating systems.
Preliminary Note:
I’m using a CentOS 5.4 x86_64 base installation in this tutorial
* server1.example.co.za (IP 10.0.0.100): CentOS 5.4 x86_64 Base installation
Install the Gitco repository
Browse to and grab the latest repo for your arch. (in this case x86_64)
# cd /etc/yum.repos.d/
# wget GITCO-XEN3.4.1_x86_64.repo
Remove previous installations of XEN before re-installing XEN 3.4.1
# yum groupremove Virtualization
# yum groupinstall Virtualization
Edit grub.conf to reflect the correct default Kernel
# vi /etc/grub.conf

Reboot the machine for new XEN kernel to take effect
# reboot
After the reboot check the Kernel to reflect the change
# uname -r
