Any advantage on using large luns+LVM instead of independent LUNs
appart from snapshots? (according to Novell support LVM on top of LVM
is a bad thing...). I remember reading that Xen itself implements some
kind of locking...

I think easier management is the key. If you're already managing the SAN and assigning LUNs to your boxen, then managing multipath.conf across your cluster, it's nice to only do that 4 times for a couple TB rather than once for each VM, for example.
