[libvirt] [PATCHv3 00/43] cleaned up snapshot series



As promised, here is my v3, which includes all the self-replies
I was scattering throughout v2:
https://www.redhat.com/archives/libvir-list/2011-August/msg00620.html

Also available here:

git fetch git://repo.or.cz/libvirt/ericb.git snapshot

or browse online at:

http://repo.or.cz/w/libvirt/ericb.git/shortlog/refs/heads/snapshot

I've tested that this can create external disk snapshots with
SELinux running using the qemu snapshot_blkdev monitor command,
then deleting the metadata for those snapshots.

Other things from my RFC still remain to be coded:
https://www.redhat.com/archives/libvir-list/2011-August/msg00361.html
support for offline external disk snapshots
support for more flags (such as starting an offline snapshot on revert)
support for revert and delete of disk snapshots
new apis for easier manipulation of snapshot hierarchies
