Public bug reported:
Currently I am running LXD on Ubuntu 15.10. I have created two
containers, controller and compute. Ive gone ahead and installed and
setup all services. The only issue I am having is with neutron-l3-agent
and neutron-dhcp-agent. After completing configuration I am seeing the
following errors:
neutron-l3-agent.log:
