What's the current status of LVM snapshots? Can you
create/revert/commit them with virsh? Or is this an out of band

Currently requires out-of-band efforts.
I've never used LVM-based images mainly because you couldn't overcommit
the storage subsystem but now, with the new thin-provisioning
capabilities of LVM, I'm willing to give it a try. That is, of course,
*only* If I can still have all the nice snapshot capabilities I
currently have with qcow2-based images :)
p.d I know you can create qcow2 overlays out of an LVM. My question
really is whether libvirt can use/manipulate native LVM snapshots these
Patches are welcome to add that functionality into libvirt.
