ok, it is there in the vdsm log:

Thread-58161::ERROR::2013-08-29
07:48:18,255::libvirtvm::2089::vm.Vm::(snapshot)
vmId=`e4226eb3-9758-4d19-a4d3-0a263189013d`::The base volume doesn't

'c7a90893-83e9-4781-905f-470a2e6b653f'}

And this is the relevant snippet from vdsm:

                 # The volume we want to snapshot doesn't exist
                 _rollbackDrives(newDrives)
                 self.log.error("The base volume doesn't exist: %s",
baseDrv)

I would suspect that this is another DB inconsistency, the engine is
sending a disk to snapshot that does not exist on the storage. Can you
still start this VM?

Thank you,
Laszlo

Hi Jakub,

Could you also share the VDSM logs from that host?

Thank you,
Laszlo

Here is the vdsm log from node

Thank you.

Ok, it is there in the VDSM log:

I can star, stop and edit this VM as normally. Only snapshots doesnt
work. It does not work for imported and even for newly created VMs.

was this resolved?

I upgraded to 3.3.0-4 (latest) oVirt and tried snapshot:

(newly created VM):

Snapshot 'test' creation for VM 'server1.testlab.org' was initiated by
admin.
Failed to create live snapshot 'test' for VM 'server1.testlab.org'. VM
restart is recommended.
Snapshot 'test' creation for VM 'server1.testlab.org' has been completed.
I can see newly created snapshot in oVirt GUI.

(imported VM):
Snapshot 'test2' creation for VM 'server2.testlab.org' was initiated by
admin.
Failed to create live snapshot 'test2' for VM 'server2.testlab.org'. VM
restart is recommended.
Snapshot 'test2' creation for VM 'server2.testlab.org' has been completed.
I can see newly created snapshot in oVirt GUI.

The clone function works as expected (created ew VM from snapshot).

thanks jakub,

can you please open a bug to track/analyze this (so it won't get lost)?

thanks,
   Itamar
