Hi Grant, Sorry to hear that. Can you do me a favor and file a bug against neutron with your env so we can try to reproduce it? Include everything like if you have l2pop enabled, which agent you are using, and which L3 settings you are using (L3HA/DVR/etc). Thanks, Kevin Benton On Thu, Dec 8, 20

Hi Kevin, Sorry for the late reply, We have tried doing that and we were still seeing the same issues. I don't think the bug was quite the same as what we were seeing. Unfortunately we have had to roll back to Mitaka as we had a tight deadline and not being able to create networks / have HA

There was a bug that the fixes just recently merged for where removing a router on the L3 agent was done in the wrong order and it resulted in issues cleaning up the interfaces with Linux Bridge + L3HA. https://bugs.launchpad.net/neutron/+bug/1629159 It could be the case that there is an orphaned

Yes, that is a misleading warning. What is happening is that it's trying to load the interface driver as an alias first, which results in a stevedore warning that you see and then it falls back to loading it by the class path, which is what you have configured. We will need to see if there is a way

I have also recently been seeing 'Could not load InterfaceDriver' warnings from the DHCP agent, and haven't yet understood that - although I'm pretty sure that my interface driver is being loaded really - or else none of my networking function would work at all. So it's possible that that part of
