Comment 1 Eyal Edri 2014-10-01 08:17:39 UTC 
this bug wasn't included in the rhev 3.4.3 tracker bug and missed the build date of the build, hence moving to 3.4.4
Comment 10 Nir Soffer 2014-10-28 16:30:27 UTC 
One patch is not merged yet - moving back to POST.
Comment 16 Nir Soffer 2014-11-02 19:40:14 UTC 
Last patch was merged in 3.4.4.
Comment 17 Elad 2014-11-19 08:53:15 UTC 
Snapshot creation succeeded while disks were created on a RHEL7 host and the VM was started and snapshot created by a RHEL6 host. Tested also the inverse scenario (created disks with the RHEL6 host, started the VM and created snaopshot with the RHEL7 host).

Tested the following matrix:
- thik disk on block domain
- thin disk on block domain
- thin disk on file domain
- thik disk on file domain
- snapshot with and without memory

Also, restore snapshots succeeded

Used rhev3.4.4 av13.1

Hosts OSs:
Red Hat Enterprise Linux Server release 6.6 (Santiago)
Red Hat Enterprise Linux Server release 7.0 (Maipo)
