Won't work (qemu is not able to load disk snapshots without memory). What libvirt does instead is to use qemu-img snapshot -c to change the snapshot back to the active layer, then boot qemu fresh on the correct contents. Of course, patches to change behavior aren't out of the question, but there's already a lot of cruft there to be aware of, and making sure we don't regress libvirt behavior. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
