[ovirt-users] Upgrade from 4.4.3 to 4.4.4 (oVirt Node) - vdsmd.service/start failed with result 'dependency'

Hi all, I have just upgraded one of my oVirt nodes from 4.4.3 to 4.4.4. After the reboot, the 4.4.4 image is correctly loaded but vdsmd is not starting due to this error: vdsmd.service: Job vdsmd.service/start failed with result 'dependency'. Looks like it has a dependency on mom-vdsm, and this as well has a dependency issue: mom-vdsm.service: Job mom-vdsm.service/start failed with result 'dependency'. After some investigation looks like mom-vdsm has a dependency on ovsdb-server, and this is the unit creating the problem: ovs-delete-transient-ports.service: Starting requested but asserts failed. Assertion failed for Open vSwitch Delete Transient Ports Failed to start Open vSwitch Database Unit. Details below: -- Unit ovsdb-server.service has begun starting up.
