[libvirt] [PATCHv3 0/5] snapshot revert-and-create

v2 was here:

One patch from v2 has already been committed.  This patch additionally
adds a qemu implementation for the new flag, and I have tested creation
of offline branches (I still need to test creation of a branch from a
disk-only or online external snapshot).  I've also started documenting
my plans for a new revert FOLLOW flag, which updates to the current
state of external files (rather than reverting completely to the
point where the snapshot was taken); once that is working, then
implementing the combination of createXML(LIVE|BRANCH) will really
be creating the branch, then farming out to revert(FOLLOW) to switch
over to the new branch.

Eric Blake (5):
  snapshot: add revert-and-create branching of external snapshots
  snapshot: prepare to parse new XML
  snapshot: actually compute branch definition from XML
  snapshot: support revert-and-create branching in qemu
  snapshot: add another revert API flag
