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.

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.
