Fixed In Version:	rhv-4.3.11-4	Doc Type:	Bug Fix
Doc Text:	Previously, exporting a virtual machine or template to an OVA file incorrectly sets its format in the OVF metadata file to "RAW". This issue causes problems using the OVA file. The current release fixes this issue. Exporting to OVA sets the format in the OVF metadata file to "COW", which represents the disk's actual format, qcow2.	Story Points:	---

+++   bug 1845473 +++
======================================================================

Description of problem: When exporting a VM to an OVA file the export succeeds, but when extracting the ovf file from the OVA file via tar the ovf metadata has its format field set to RAW. An inspection of the actual disk file via qemu-img info shows that the disk format is actually qcow2.


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


How reproducible:


Steps to Reproduce:
1. Export as an OVA file a VM with a disk attached
2. Access the Host and use tar xvf to extract the vm.ovf file and the disk
3. open the ovf file and search for the format

Actual results:

The format is set to RAW


Expected results:

The format should be set to COW


Additional info:


Use "qemu-img info " command on the disk file to verify the format is qcow2.

Adding to the above that the disk should be of type RAW and with no snapshots.
