Fails because of this:
ERROR ] dwhd is currently running. Its hostname is ovirtdwh01prod Please stop it before running Setup.

There is no host anymore!!!!!

And yes I tried the bug work around and no it didn't work... And yes I'm getting a little bit frustrated about updating oVirt lately.. Sorry...
