Description Dan Winship 2020-11-18 13:51:51 UTC

In 4.7 and 4.6, we've started seeing this error message in ovs-vswitchd.log:

2020-11-17T12:20:50.895Z|00033|bridge|ERR|interface br-ex: ignoring mac in Interface record (use Bridge record to set local port's mac)

This is apparently harmless but it confuses people so we should root it out.

I'm pretty sure this is NetworkManager's fault so I'm going to file a bug against them and then this bug can track us getting the fix into RHCOS.

Ha, nope, figured it out while isolating a reproducer :-)
