[Xen-users] Xen and SAN : snapshot XOR live-migration ?

[Franck ELIE <Franck.Elie@xxxxxxxxxxxxxxx>]

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 ?

Regards

 Franck
