Yes, this is...

...precisely what I meant by 'disk-only' snapshots.  As long as you
don't need the associated VM state (that is, if you are okay that
reverting to the snapshot implies that any in-flight memory that has not
been flushed to disk will be lost, and that the disks will probably need
fsck), then this is indeed the way to go.
