Please tell me if I am wrong :
Xen needs LVM to perform domU snapshots and snapshots must be
performed by dom0.
I'm confused. Why Xen would need LVM to perform any snapshots at all?
OK, I forgot to say that for me, LVM snapshot seems to be a good
solution in order to perform a pseudo transparent backup (without to
shutdown or to perform a "pause" of the domU).
But if we do not need to keep domU up 24h/24h, it is possible to use
other way to perform snapshots ; for example with a basic "xm pause" ;
copy of domU ; "xm unpause" (if you do not have databases, etc.)
