On the oVirt CI env ( http://jenkins.ovirt.org/view/oVirt%20system%20tests/
) we are still testing over CentOS 7.3 without CR repo.
We prefer avoid consuming CR repo there since we had bad experience in the
past with repo incompleness mining the stability of the CI env.

CentOS is a "rolling" distro, so as soon as the 7.4 updated packages will
get officially released, our CI env will start consuming them and you could
check the output.
So I'd suggest to wait a few days after the release before upgrading your
production system to Centros 7.4 or to locally set up a testing env and
helping us reporting any suspect behavior.

RHEL 7.4 is the tested baseline
