These are not related. The Quantum service enables the user to configure 
the network configuration. The DHCP agent provides the IPAM 
implementation and the L3 agent provides the floating IP and routing 
support.

Yes, it would be nice if the user was able to know if there was a 
problem, but it is not related at all to the Quantum API. In actual fact 
the administrator is able to invoke the command: "quantum agent-list" to 
determine if there are any issues with the backiend implementation of 
the Quantum API's. The administrator would in turn need to address the 
issues.

 From the traces it looks like the l3 agent has successfully connected 
to the message broker. The DHCP agent is unable to connect to the 
message broker. This may be during the boot process where it may take up 
to a minute (this is due to the qpid timeouts)
