Hi, Can you try this command: virsh snapshot-delete serv1r2 snap --metadata On Wed, Aug 23, 2017 at 4:41 PM, Doug Hughes <doug.hughes(a)keystonenap.com <mailto:doug.hughes@keystonenap.com>> wrote: I'm not sure how this snapshot got created, but, I cannot delete it, and its presence prevents me from creating other snapshots.

I had the same problem yesterday. I found the solution from this article https://kashyapc.fedorapeople.org/virt/lc-2012/snapshots-handout.html. According to the article it deletes the tracking metadata by libvirt. You can physically remove the snapshot now that there is no tracking stream data by libvirt On Wed, Aug 23, 2017 at 4:56 PM, Doug Hughes <doug.hughes(a)keystonenap.com <mailto:doug.hughes@keystonenap.com>> wrote: THat did it!
