Version-Release number of selected component (if applicable):
4.4_master

How reproducible:
100%


Steps to Reproduce:
1. Create a VM with disk
2. Run the VM  
3. Create a snapshot with memory
4. Deactivate and detach the storage domain which holds the memory disks
5. Attach the storage back
6. Import the VM back to the environment

Actual results:
VM imported with the snapshot but without the memory disks 

Expected results:
VM should be imported with the snapshot and with the memory disks
