I think I've addressed most findings from round 3 - by implementing
the ability to redefine a snapshot, it becomes possible to restore
snapshot hierarchy when recreating a transient domain by the same
name. New goodies in this round: several bug fixes, add virsh
snapshot-edit, drop undefine --snapshots-full (you can only remove
snapshot metadata on undefine). I tested as I went, but this went
through so many rebases that there may be some nasties that snuck
in; but I wanted to get this posted now. I also know that I'm
missing at least one major feature requested in the v3 review:
namely, transient domains _should_ auto-remove snapshot metadata
files when they halt, but right now aren't doing that.
v3 was at:
https://www.redhat.com/archives/libvir-list/2011-August/msg01132.html
Also available here:
git fetch git://repo.or.cz/libvirt/ericb.git snapshot
or browse online at:

I'm also trying to group things by several bugzilla related to
various patches (looks like I still need to create a few):
