You don't really need shared filesystems if you are doing direct
block io to LVs or raw partitions as the Xen migration will handle
the hand-off, but you will if you are using flat files, because of
this I recommend using LVs or raw partitions as clustered
filesystems will put a serious overhead on the Xen guest io.

Ross,
I can use DRBD to mirror data between the two storage servers and
iSCSI to export the block devices, but how will iSCSI cope with
failure of one storage server?
Can I use heartbeat and CRM to failover the host IP and iSCSI target
to the other storage server?
Regards,
Tom
