Xen is a free open source software virtual machine monitor for Intel / PowerPC architectures. It is software that runs on a host operating system and allows several guest operating systems to be run on top of the host on the same computer hardware at the same time (just like VMWare software). Luckily Installing and managing XEN is quite easy under CentOS 5 Linux.

Arun Singh shows us how to create shared storage on SUSE Linux Enterprise Server 10 using OCFS2 (Oracle Cluster File System v2 for shared storage) and Xen Virtualization technology. Enterprise grade shared storage can cost you lots of money but here no real expensive shared storage used. The information provided here works with real shared storage as well:
This paper is to help you to understand the steps involved in creating shared storage without using expensive shared storage. Using this information you can create shared storage used by all xen guest OS and Host, avoiding copying of files between guest OS’s. Hope you will find this paper useful.
You can easily port instructions to Redhat or any other Linux distro without a problem. You can also use Redhat’s Global File System (GFS) too. We often use Fibre Channel or iSCSI, devices for GFS shared storage.

On a related note there is also article about creating a highly available VMware Server environment on a Debian Etch system.
Update: Download latest OpenSuse Linux version 10.3.
I know most of us tired of answering questions about the Microsoft-Novell deal.. but OpenSuse Linux 10.2 is here….
openSUSE is a community project, sponsored by Novell, to develop and maintain SUSE Linux components (such as YaST).
Some of the Good application included:
* AppArmor: gives certain applications rights based on how they run and interact with the environment.
* YaST: a system management application
* Xen: virtualization software
* The KDE and GNOME desktop environments and many more
