I'll work on it some more. I have 2 different clusters in the data center
(1 is the Hosted Engine systems, another is not..) I had trouble with
both. I'll try again on the non-hosted engine cluster to see what it is
doing. I have it working in 4.1, but we are trying to do a clean wipe
since the 4.1 engine has been upgraded so many times from v3.5 plus we want
to move to hosted-engine-ha from a single engine node and the ansible
modules/roles (which also have problems..)

OVS switch support is experimental at this stage and in some cases when
trying to change from one switch to the other, it fails.
It was also not checked against a hosted engine setup, which handles
networking a bit differently for the management network (ovirtmgmt).
Nevertheless, we are interested in understanding all the problems that
exists today, so if you can, please share the supervdsm log, it has the
interesting networking traces.
We plan to block cluster switch editing until these problems are resolved.
It will be only allowed to define a new cluster as OVS, not convert an
existing one from Linux Bridge to OVS.
