Version-Release number of selected component (if applicable):


How reproducible:
100%

Steps to Reproduce:
1. Create a VM based on Template
2. Try to export the VM (It reproduced even if the Template is in the Export Domain and also if it doesn't)
3. 

Actual results:
The export of the VM fails

Expected results:
The export should succeed

Additional info:
