Hi,

I have 2-host oVirt setup with 2 Data Centers, one with local storage domain (DC #1) for VMs + Export domain on NFS, another with all NFS shared (DC #2).

Trying to export VMs from DC #1 to DC #2.

VMs are exported to DC #1 export domain (NFS), then domain put into maintenance mode and detached from DC #1.

Unfortunately, attaching it to DC #2 failed. Logs attached. Tried to run this command twice.

Workaround are possible in order to accomplish this task, yet it would be better to do in a way as it was designed.
Thanks.
