Will OVN provider be mandatory for all engine 4.2 installation? Can OVN provider be installed on different host than engine? If not mandatory or "may be on different host", then it should be handled similar way as DWH, so it should be in separate package and it's engine-setup part should also be in separate package.
In 4.2, OVN provider is configured by default on the Engine host, but the user can opt to avoid that. He can then configure the provider manually, and add it manually to Engine. We have already limited the automatic configuration of OVN to the case of it running on the same host. When looked from this perspective, adding an explicit rpm-level Requires, does not make things much worse, it only makes reality visible.
And even if we don't support OVN on different host in 4.2, we can prepare for the future ...
A big question is whether that future includes installing things on a remote host (as in DWH), or alternatively spawning a container. Implementing the OVN deployment to the Engine machine took quite a big effort[1]. I worry that extending it to allow remote host would be even more consuming, it's not a minor preparation but a mid-size feature on its own.
