Description Dominik Holler 2020-03-02 13:25:16 UTC
OVS switch type for nmstate managed hosts is currently known to be not working (Bug 1809102).
For this reason the user should be not able to add a RHEL8 host to a Cluster OVS switch type.

Comment 3 Martin Perina 2020-03-17 12:33:15 UTC
We don't know what OS is installed on the host on engine before installation, so the only way how to prevent adding EL8 host into OVS cluster is to fail adding it. Also this is temporary only solution until we remove current OVS related code in VDSM and replace it with nmstate (which should happen in one of the earliest z-streams)

The Doc Text field looks good, 
As for your question - yes, they shouldn't upgrade
