I'm running oVirt 4.4.4 with two data storage domains. One domain is where the
production VMs run. The second domain is where I make backup copies of the VMs in the
event of problems with the main production VMs. I make backups using the export option
from the GUI's dropdown list.
I just now tried to "restore" a backup copy via the export function and get an
error. In fact, I get errors trying to export (import to my original data domain) any of
the VMs that were exported to my backup data domain. My backup domain is a DATA domain
and not an EXPORT domain.
The exact error is:
Export VM Failed
[Cannot add VM. Cannot find a disk profile defined on storage domain
246c69e9-6f16-489f-8022-8613f6c1c22a.]
Is this a bug or am I doing something wrong? Help is needed urgently. In advance, thank
you.

Sounds like a bug, can you attach the output of:
$ psql -U engine -d engine -c "\x on" -c "select * from
disk_profiles"

I believe I have significantly relevant information to help isolate the problem and I do
believe it is a bug.
First, I previously said that "all exported VMs" were affected. That is
incorrect and therefore misleading. I apologize.
The problem at hand appears to have to do with preallocated vs thin provisioning of
disks.
Again, I am running oVirt 4.4.4 at the moment.
All VMs that only have preallocated disks have the problem. When they were exported, the
disk profile remained the original profile from the source data domain. Thus, the error
"Cannot add VM. Cannot find a disk profile defined on storage domain" when
trying to re-export them back the other direction.
VMs that have only thin provisioned disks or a combination of both types do NOT have the
problem. When exported, all disks get the disk profile from the destination domain.
Re-exporting them back the other direction works.
Please let me know if I correctly identified a bug. More importantly, please let me know
if it has been fixed since 4.4.4 and what I can do in the mean time. I really need to
"restore" one of my VMs that is stuck in limbo because of the incorrect disk
profile.
Your prompt response is greatly appreciated.
