Right now, libvirt documents that it refuses to delete external snapshots only because it is not implemented safely; this bug represents a hole where we aren't following the documentation. Alternatives are to patch code to match docs (quick), or to actually implement snapshot deletion (longer, but more desirable). I see no need to do a quick patch now only to undo it later when true snapshot deletion is implemented. Upstream proposed patch: https://www.redhat.com/archives/libvir-list/2014-October/msg00823.html Change to VERIFIED status. Steps as below: # virsh snapshot-create-as rh7 internal Domain snapshot internal created # virsh snapshot-create-as rh7 external --disk-only Domain snapshot external created # virsh snapshot-delete rh7 internal --children error: Failed to delete snapshot internal error: unsupported configuration: deletion of 1 external disk snapshots not supported yet # virsh snapshot-delete rh7 internal --children-only error: Failed to delete snapshot internal error: unsupported configuration: deletion of 1 external disk snapshots not supported yet Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
