I think the "consistent snapshot" term is not defined.  Please add
something like:

"Consistent snapshots are snapshots that exist in all writeable block
devices.  When 'savevm' takes a snapshot it uses the same ID across all
writeable block devices.  If a snapshot ID only exists in one block
device then it is not a consistent snapshot."
