Tests pass on Fedora 28:
https://travis-ci.org/nirs/vdsm/jobs/413702715
Fedora rawhide fails with various issues, will open another
thread about it.
Still failing on CentOS in the ovs tests:
https://travis-ci.org/nirs/vdsm/jobs/413702714
(see errors bellow).
So maybe we need to mark tests as xfail only on CentOS - or
maybe the fact it works on Fedora means we don't understand
the failure yet?
We don't know what is the vm running our tests, but we control
the CentOS/Fedora container. Maybe something is missing in the
CentOS container?
