The oVirt source code and DB still contains places in which we refer to version 2.2, which is no longer supported. Please remove these references.
Caught one of them as part of the cleanup I handled in http://gerrit.ovirt.org/#/c/31266/.
Please make sure someone from the storage team either reviews or collaborates on the changes required to storage classes (VersionStorageFormatUtil, DataCenterStorageListModel).
The other usages are tests (GetCommandsCompatibilityVersionsQueryTest, UpdateVmCommandTest) and the declaration of this constant in Version itself.
I'd be happy to review/collaborate on those too if needed.
This bug was fixed and is slated to be in the upcoming version. As we
are focusing our testing at this phase on severe bugs, this bug was
closed without going through its verification step. If you think this
bug should be verified by QE, please set its severity to high and move
it back to ON_QA
