Description of problem:
We point at , but on RHEL, $releasever is 7Server, which does not exist.
Not sure if we try to support rhel. On centos it's '7' which works.
If we do, need to either fix the source (find some yum var that returns
'7' in such a case, or hard-code '7' during building the file) or ask
centos to add a link.
ovirt-release-master has been updated with the fixing patch.
Red Hat Enterprise Linux Server release 7.2 (Maipo)
name=CentOS-$releasever - oVirt 3.6
