Export VM as OVA to host without /dev/loop devices. Verify VM exported successfully with disks. 2. Reboot host in order to clear /dev/loop. and import the exported OVA. OVA imported successfully, run VM and verify VM is running and VM configuration is correct. 3. Export VM as OVA when to host with /dev/loop devices. Verify VM exported successfully with disks. 4. Verify /dev/loop device created, import the exported OVA. OVA imported successfully, run VM and verify VM is running and VM configuration is correct. 5. Repeat steps 1-4 few times.

It looks like is the same issue as this one here: https://bugzilla.redhat.com/show_bug.cgi?id=1813028 but for the extract_ova.py instead of the pack_ova.py from the 18103028 Version-Release number of selected component (if applicable): 4.4.8 How reproducible: idk, 50/50 I guess? Steps to Reproduce: 1. Have a vm exported as OVA 2. Import it 3. Actual results: fails Expected results: succeeds Additional info:
