Hello Chris,

I'm sorry I can't help you here. I'm quite new to this list and just saw some 
kind
of coincidence between our problems. From my observations I would say that
the engine breaks the settings. At least in my case the webinterface component
that does not fill calls in the background correctly. From my understanding 
VDSM 
& libvirt should only be fed by the engine. 

My idea would be to have a look at the database table/view vm_device and its
column address. A quick look before and after could show differences. 

> su - postgres
> psql engine postgres -q -n -c "select * from vm_device where type='disk';"

Take care! I could be totally wrong.

Best regards.

Markus

Betreff: RE: [Users] oVirt 3.3 -- Failed to run VM: internal error unexpected 
address type for ide disk

Hi Markus,

Thanks for your email. I followed your instructions (detach/attach virtio 
disks, also tried detach/remove/add/attach virtio disks as well) however the 
VMs still fail to start with the same error.

Note that the issue persists after upgrading to oVirt 3.3.0-3 while keeping 
VDSM/libvirt the same.

I'm not too familiar with the whole VM creation/destruction process - where 
would the root cause of the problem likely be? Is it ovirt-engine breaking the 
VM definition file when it records the VM as being shut down, or libvirt/VDSM 
sending bad information back to the engine during the destruction process, or 
something else?

Cheers,

Chris

Hello,

not so critical but I had a similar error after switching disk from virtio to 
virtio-scsi.
http://lists.ovirt.org/pipermail/users/2013-September/016256.html. In this case 
a simple detach/attach process solved the problem permanently.

To check we have no regressions I patched to 3.3.0-2 in my NFS based setup with 
Virtio-SCSI disks to test your findings. Luckly the "loose your disks after 
every reboot" does not occur.

Markus
