[ovirt-users] can't import vm from KVM host

[Nelson Lameiras]

I upgraded to oVirt 4.0.4 RC1 to test this issue (engine and hosts) and I still have the same problem.

Migration GUI still shows zero disks when the source VM had block disk devices.

Can you confirm that the issue 1362525 has been integrated in this RC?
Should I do some additional actions in order to see/make it work?

Thanks,
Nelson

Yes,
This was the issue as well - seeing zero disks when the source VM had block disk devices.

Adding Nisim to verify it.
