I can see that MOM is failing to start because some of the MOM dependencies is not starting. Can you please post output from 'systemctl status momd'?


 
 ● momd.service - Memory Overcommitment Manager Daemon
   Loaded: loaded (/usr/lib/systemd/system/momd.service; static; vendor preset: disabled)
   Active: inactive (dead)

perhaps any other daemon status?
Or any momd related log file generated?

BTW: I see on a running oVirt 4.3.5 node from another environment that the status of momd is the same inactive (dead)

 
What happens if you try to start the momd?
