Hi all!
I'm getting this strange message on my vdsm.log
Thread-187887::ERROR::2014-02-07

Anyone know what could be happening?
Hi Eduardo,
I'm afraid you have a vm with an invalid drive, created without the required
"format" attribute.
We have seen this issue when upgrading from old versions, or when migrating vms.
See https://bugzilla.redhat.com/show_bug.cgi?id=1055437
Can you add more information that will help debug this issue?
- ovirt-engine/vdsm versions
- logs: engine.log, vdsm.log
- what was the trigger of this error (e.g. started when migrating vm?)
If you think your case is not relevant to bug 1055437, please open a new bug.
Thanks,
Nir
