I have a problem with DHCP agent. When I try create a network and respectible subnet, with neutron server, the dashboard show me that the network have created correctly, but when I look the server.log it shows this:

ERROR neutron.api.rpc.agentnotifiers.dhcp_rpc_agent_api [-] No DHCP agents are associated with network '34d80f09-f477-4f20-8257-bfb2dc3fa9f3'.

I use ubuntu 12.04 and Havana versions. Looking on Internet, I found this bug report: I would like to know if the bug was fixed or are yet in progress?
