Well, I've spent the last 2.5 days trying to get oVirt 4.2 up and running.
I sneeze on it, vdsm has a conniption and there appears to be no way to
recover from it.
1) Install 4.2. Everything looks good. Start copying over some
data..accidently wipe out the master storage domain...It's gone. The
only method google could suggest was to re-initialize the data center.
Great. I'd love to! It's greyed out. Can't get it back...Try several
hosted-engine uninstall methods, including
/usr/sbin/ovirt-hosted-engine-cleanup and wiping out the storage.
re-run hosted-engine --deploy
All I get over and over in the vdsm log file while waiting for vdsm to become
operational is..

sigh...reinstall 7.4 and do it all over again.
2) copying data to master storage pool. Didn't wipe it out this time, but
filled the volume instead. Environment freezes.
vdsm can't start...infinite loop waiting for storage pool again. Try clean up
and redeploy. Same problem as above.
7.4 reinstall #2 here we go...
3)Up and running again. Forgot to add my NIC card. Shut it down. Boot back
up. vdsm sees new network interfaces.
for some reason, it switches ovirtmgmt over to one of the new interfaces which
doesn't have a cable
attached to it. Clean up ifcfg- files and reboot. ifcfg-ovirtmgmt is now
gone. recreate and reboot. Interface
comes alive, but vdsm is not starting.
supervdsm log shows:

QoS report (network: ovirtmgmt, ports: ['enp3s0', 'enp4s0'])

Remove new nic. reboot. vdsm once again stuck waiting for storage pool to
come up.
So this is where I'm at now. Stuck. once again.
I've been running 3.6.3 All In One for many years because I've been concerned
about the complexity of the self hosted
configuration. Guess I was right.
Google shows lots of other people also concerned about the stability of
oVirt..It's great when it runs, but
any little issue and you're basically reinstalling from scratch.
