Hi, extract from [1] ((side note: I couldn't find that in config reference for Mitaka) is: "disable_libvirt_livesnapshot = True (BoolOpt) When using libvirt 1.2.2 live snapshots fail intermittently under load. This config option provides a mechanism to enable live snapshot while this is resolved. See https://bugs.launchpad.net/nova/+bug/1334398"
I am not sure if Nova behaves like that in case you have disable_libvirt_livesnapshot=True (default in Liberty and Mitaka apparently...) In case it is not about that, then I would try to do it manually using something like [2] as guideline to see if it succeeds using Libvirt/QEMU without Nova.

When with try to do a snapshot we get a success message, but the snapshot is only showed shortly in the imagelist with status deleted. I we shutoff the instance and then do a snapshot it is working without problems. When we use a cinder volume as root disk instead an ephermal root disk a volume snapshot could be made without problem in running state of the instance. The same behaviour we have on an other installation of mitaka from our colleagues. Is this behaviour normal in Mitaka or ist this maybe a bug? Because in Juno we could do snapshots from running instances without problems. Regards, Michael Michael Stang Laboringenieur, Dipl. Inf.
