Sorry this never received a response. Not sure what was going on here, could be that hda1.qcow2 wasn't actually a qcow2 file, or there was a libvirt bug. Either way, snapshotting definitely works nowadays, so closing as DEFERRED. If anyone is still hitting similar issues with latest libvirt, please file a new bug, and provide full domain and snapshot XML being used
