VM previously imported as OVA missing after detach/import of Data Storage Domain

[ahadas]

VM previously imported as OVA, is not visible in the "VM Import" Tab of Data Storage Domain after the Storage Domain has been put in maintenance/detached/removed, then imported/activated. Hence VM configuration is lost and can't be imported, although its disks are visibles with no alias/name in "Disk Import" Tab.

Other VM created (not OVA imported) on the same Data Storage Domain has no issue.

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

How reproducible: 100%

Steps to Reproduce:

1. import VM1 from OVA file to a Data Storage domain
2. create VM2 on the same Data Storage domain
3. Maintenance/Detach/Remove Data Storage Domain from Data Center
4. Import/activate Data Storage Domain in the same Data Center
5. VM1 won't appear in the Storage Domain "VM Import" Tab => VM1 configuration is lost. Its disks are visibles with no alias/name in "Disk Import" Tab.
6. VM2 is visible the Storage Domain "VM Import" Tab => VM2 import successful

Actual results: VM lost after Storage Domain Detach/Import

Expected results: VM should be visible to import
