Version-Release number of selected component (if applicable):
ovirt-engine-4.3.5.4-0.1.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. I've exported a VM with 1 disk to an OVA
2. Import the OVA with another name. No errors in the event log.
3. Start the new VM, but it cannot find grub. A disk was created but looks empty.

Actual results:
The disk was not imported.

Expected results:
A successfull import or at least the import task failing.

Additional info:
If adding no_root_squash to the SD NFS share, the image is imported successfully.
