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.

I'm getting further along with 4.2.2rc3 than the 4.2.1 when it
comes to hosted engine and vlans.. it actually does install
under 4.2.2rc3.
But it's a complete failure when I switch the cluster from Linux
Bridge/Legacy to OVS. The first time I try, vdsm does
not properly configure the node, it's all messed up.
I'm getting this in vdsmd logs:

So something is dreadfully wrong with the bridge to ovs
conversion in 4.2.2rc3.
