Comment 6 for bug 1849392

@ivve The setup is with HA and no DVR. I've also tried using a non-HA router but encountered the same issue.

I've tried Donny's trick and it seems to work. Restarting the L3 agent on all controllers does allow the namespace to be created and the qrouter to exist. I see that the ports are up as well. I'll see if connectivity works.
