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.
