This log does not show anything except the corruption in the previous run. What we need is libvirtd.log from /var/log/libvirt/libvirtd.log. The log usually does not exist since it is too verbose to enable by default. You can try to enable libvirt logs temporarily, see: https://libvirt.org/kbase/debuglogs.html Nir

Helo Nir, No I do not have libvirt logs enabled. I restored the vm from the snapshot and retried. It did boot but at the same time it did not merge again when I tried it. On the other hand when I cloned it and tried to recreate the situation the image did merge. Is it possible that the image is corrupted for any reason beyond live merge failure,so the merge fails regardles? This is a production vm so I cannot play a lot with it :-( I should probably clone it give the clone to production and see if this continues to happen.

I see you are using ovirt 4.3.10 - we fixed some snapshot deletion issues in 4.4. For your case I would try to: 1. Clone the VM - can you delete the snapshot in the clone? 2. Shutdown the clone - can delete the snapshot when the clone is shutdown? Please file a bug and attach vdsm and engine logs showing the timeframe when you tried to delete the snapshot. Nir
