I'm having an issue were it looks like the linuxbridge is not configured with the physical interface. This is causing an issue sshing/pinging my instance.

root@prod-openstack-controller1:~# brctl show
bridge name     bridge id               STP enabled     interfaces
brq319e7153-80          8000.928506805356       no              tap0965586e-88
consul0         8000.000000000000       no
virbr0          8000.525400542811       yes             virbr0-nic

have configuration in linuxbridge_agent.ini to assign the networks to the interfaces

physical_interface_mappings = public:ens192,private:ens224

Is Openstack supposed to auto detect the interfaces? How can I troubleshoot this issue?

Have you checked neutron logs for any hints? What do your configs look like, especially in /etc/neutron/plugins/ml2/ml2_conf.ini the value for mechanism_drivers?

Failed reporting state!: MessagingTimeout: Timed out waiting for a reply to message ID fb0447cd1c4a4100970812b79647a69c

mechanism_drivers = linuxbridge

The above error message is from linuxbridge log. I don't think the messaging agent is causing a bridge issue though.

I don't see any error message in your question, could you update it then?

After I followed the guide at ( the interfaces started to show up in brctl show.

Originally I had created the networks through the Horizon Web UI and the networks I had configured in ml2_conf.ini and linuxbridge_agent.ini, were not assigned to the networks that were created through the webui.

I discovered this by running openstack network list openstack network show ID
