This is clearly a mom bug. Mom must have retry mechanism when and do not expect that vdsm is ready to accept connections when mom starts. Vdsm can be nicer and notify systemd when vdsm is ready. I already mentioned it in the other thread here: http://lists.ovirt.org/pipermail/devel/2016-November/014104.html But even if vdsm did this, mom still needs a retry mechanism.
