What you are
talking about is a HA (High Availability) setup

If what you want is really just one server backed by a hot spare, then
you don't need Xen at all. The easiest way to do this is using heartbeat
for high availability and DRBD to replicate the data. Heartbeat v1 does
this very well and is fairly easy to understand. Unfortunately, all the
HA developers want everyone to run the latest version of heartbeat (v2
or v3) or corosync, with pacemaker and despite what they sometimes say,
this is a very large basketball to swallow. It is massive overkill just
for a pair of hot spare servers with a shared IP address. But it is
difficult to find anyone who will help you with heartbeat v1 since it is
"obsolete", but you may be able to figure it out yourself.

The official documentation for HA on Linux is at
http://www.linux-ha.org/ and http://www.drbd.org/

Thanks I heard of remus http://wiki.xensource.com/xenwiki/Remus that could do something similar. Let me look at your suggestions. Many thanks to the list.
