You can also use normal LVM over shared iSCSI LUN,
but you need to be (very) careful with running LVM management commands
and getting all the nodes (dom0s) to be in sync :)
(Citrix XenServer does this, but there the management toolstack
takes care of the LVM command execution + state synchronization).
