Fedora 22 is going to have dnf instead of yum. Currently, the job fails with
# yum install -y /tmp/*rpm
Yum command has been deprecated, use dnf instead.
due to that.
I did not verify my over-optimistic patch https://gerrit.ovirt.org/#/c/40306/ which is not enough to solve the issue.
Until this is done, the job should be disabled, as it persistently fails.
