Hello Dafna,
If a failure happened and the stateless vm has shut down without delete of the snapshot, the next time you will try to run it we will try to delete the snapshot. from the engine log, it seems that there is a problem deleting the snapshot because of quota. can you please try to disable the quota and try to run the vm again? Quota were not enabled on this Data Center, I have never done anything with quota on oVirt. The 'quota' table was empty, and the 'quota_id' field on all VMs in the 'vm_static' table was NULL.
Since it was seemingly trying to set the quota_id for this particular VM to '00000000-0000-0000-0000-000000000000', I manually inserted a record into the quota table using this ID. After that, I was able to start te VM. The quota_id field for the VM now contains a reference to this fake id.
Please note that the first time you will run it after disabling the quota, the snapshot should be deleted but the vm will still not start. only after the snapshot is deleted you will be able to run the vm again. Indeed, it took two attempts to start the VM.
Question: is it harmful to leave the fake quota record with id '00000000-0000-0000-0000-000000000000' and the reference to it in the vm_static table in place?
Cheers, Martijn.

Hi,
After maintenance on a host, I am trying to start a VM that has been running statelessly for a while. It refuses to start and Engine logs the following:
2013-12-05 11:59:18,125 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector]
(pool-6-thread-48) Correlation ID: 43d49965, Job ID: 0d943a6d-9d65-4ac1-89b7-139d30b4813c, Call Stack: null, Custom Event ID: -1, Message: Failed to start VM WinXP, because exist snapshot for stateless state. Snapshot will be deleted.
Should I submit a bug report for the poor English in this log line? ;-)
The 'Snapshots' tab for the VM doesn't show anything, but repeated attempts to start the VM just show the same message in the log.
What can I do to start this VM? It seems I missed some info in the log that may well indicate the root cause of this issue. Please see attached log excerpt. A database query is failing due to a foreign key constraint violation.
Please advise how to fix the database inconsistency.
Regards, Martijn.
