Failover hosts using Xen, DRBB and Heartbeat

After quite a lot of reading and a morning playing I managed to get failover Xen hosts working.

The idea was to have 2 physical servers to run 2 (or more) Xen hosts between them. If one server was to die or needed some work doing
on it then the domU would automatically move to the other node.

I've done some testing and all appears to work fine. However let me stress that this is not live migration so you would suffer about a minute or so outage
(not really a big deal in the grand scheme of things).
