Michal is totally right, it gets really messy.
If you have a live or offline Nova instance, and you're running current
OpenStack stable release (e.g. 'Juno').
You can trivially make a snapshot:
$ nova image-create vm snap1-of-vm --poll
And, can boot instances off based on it:
$ nova boot --flavor 1 --key_name oskey1 --image snap1-of-vm newvm
--
