So we're back in square one. Another possible culprit may be ansible: Vdsm is stopped two seconds after it logs to the host.

could it be that it triggers a systemd-reload that makes systemd croak on the vdsm-mom cycle?
We are not restarting VDSM within ovirt-host-deploy Ansible role, the VDSM restart is performed in host-deploy part same as in previous versions.
Within ovirt-host-deploy-firewalld we only enable and restart firewalld service.
comparing a successful add-host flow [1] to a failed one [2] we notice that in the failed add host ansible logs in twice (session 10 and session 11). Could it be somehow related? Notice that Session 11 uses the OLD way (awk+grep based) to find vdsm's version. Aug 30 05:55:53 lago-basic-suite-master-host-0 systemd-logind: New session 10 of user root.
