If the snapshot was already removed, ovirt should detect this and complete the operation successfully. Please file ovirt bug for this, and attach engine and vdsm logs showing the effected snapshot and disk snapshot id. You can get find the snapshot id is the UI. You can see the disk snapshot id in vm > snapshots > disks > disk id Then grep engine and vdsm log for the disk id an attach all the logs mentioning this disk id. It will be also useful to get a database dump so we can see what engine knows about this snapshot. Benny, can you recommend some queries to extract relevant info? Nir
