[CentOS] Xen on CentOS 4.3

Hello,

Has anyone set up Xen on an existing CentOS 4.3 system?  Does it work
well, or is it better to wipe the system and start clean?  I haven't
found a lot of information about this specifically.

Secondly, I have found on the xen source website downloads for xen 3.02,
which are meant for FC4 or RHEL (U1).  I'm tempted to try the RHEL
downloads, but I don't have any spare machines to test on, so I'd have
to do it to a live system (!).  Even though the xen download is for RHEL
U1, will it work on RHEL U3/CentOS 4.3 machine?  Has anyone tried this?

I'm anxious to consolidate three of my servers onto one under used
machine because one of the three is going to suffer a HD failure soon
(it's locking up every now and then, and I hear the HD making clicking
noises!).

Thanks in advance for any tips or comments.

Regards,

Ranbir
