Under libvirt 1.1.1 snapshot support is incomplete. Source: http://wiki.libvirt.org/page/I_created_an_external_snapshot,_but_libvirt_... In regard to snapshotting (features and stability), I have selected these versions of libvirt and qemu: Libvirt >= 1.2.9 (currently 1.2.12) Qemu = 2.1.0 On Qemu 2.3 and 2.4, I have experienced a regression bug regarding external snapshots. I haven't tested 2.5 yet. I've read some ware about using an older qemu but I can't find the webpage anymore.
