Note that "virsh save" will save the memory image of the domain, then
shut it down. It's not really a snapshot--more like a checkpoint.

You probably want something more like

     su -c virsh snapshot-create <domainname> <xmlfilename> --atomic

to create a real snapshot and leaving the domain in a run state. As I
said, look at the "SNAPSHOT COMMANDS" part of virsh's man page to get
the real lowdown.
