Description Alex Stupnikov 2020-12-22 17:47:32 UTC

Description of problem:

Our "NETWORKING WITH OPEN VIRTUAL NETWORK" Guide [1] is focused on overcloud deployments with ML2/OVN mechanism driver. On the other hand, ML2/OVN is default mechanism driver in RHOSP 16.

As a result, some customers would deploy their overclouds without providing any additional OVN-related environment files. It looks like that in this case they will get semi-functional overcloud because OVNCMSOptions would not be defined for controller role and OVN routers could be scheduled on Compute node, which doesn't have br-ex.

One of the customers reported such situation, which would be fixed by adding definitions like [2], but this still looks like a valid bug...

This is specific to network deployment not the framework itself, moving to Networking DFG.
