Do I even tell you how I do the conversion from legacy to OVS?
It does use ansible, and creates the vdsm nework configuration in /var/lib/vdsm for an
OVS/OVN based network.
It works great, the nodes join right up to oVirt engine with no configuration needed.
But I know that's unsupported. :)
But if your using Hosted Engine, you cannot use OVN/OVS on the Hosted Engine nodes with
the 4.2.3 release because VDSM no longer creates the proper VM config.. which also means
it's a chicken/egg problem. What comes first, the engine or the ovn controller?
