Please tell me if I am wrong :Xen needs LVM to perform domU snapshots and snapshots must be performed by dom0. By the way, a LVM volume group should not be used by more that one kernel at the same time. So if we use a SAN storage, one volume group should be activated on only one server and deactivated on the others. But if we do that, it should not be possible to perform live migration of domU. My conclusion would be that we have to choose between snapshot or live-migration, but with xen 3.0.3 we can not use both. Don't you think so ?
