you don't need such a cluster. You have to enable relocation in the
xend-config.sxp file, and the guests have to be reside on a network
storage, like NFS (for file based guests), SAN (fiberchannel) or ISCSI.
Many people here using gfs (global file system) which is a cluster
filesystem.

Can't I migrate a domU wich is using LVM storage?
Neither in non-realtime?
You can shut it down, image it, and boot the image on the other machine. With your DHCP and DNS setups done correctly, you can even edit the config file when transferring it and have it boot as a separate machine, but from an identical OS image. The trick is useful for development.
