Public bug reported: On my single-node devstack setup running the latest neutron code, there is one AgentNotFoundByTypeHost exception found for the L3-agent. However, the AgentNotFoundByTypeHost exception is not logged for the DHCP, OVS, or metadata agents. This fact would point to a problem with how the L3-agent is starting up.
