Libvirt already tracks the config at the time of the snapshot. Revert is _supposed_ to refuse to happen _unless_ the config is API compatible or if you pass a force flag; you may be tripping up on bugs in libvirt where intention is not matching reality. Or is virt-manager using the force flag? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
