What are you trying to copy-on-write?  Is it just disk state, or VM
memory state?  Do you have corresponding qemu commands that you are
trying to figure out if virsh maps to those same commands?  There's a
lot of flexibility in the virsh snapshot XML, but not all of it has been
wired up yet (in part because it's still a moving target for what
upstream qemu supports), so knowing more details about what you are
trying to do will help us better answer whether it can be done now and
if so with which commands.
