Issue with neutron agent-list

I'm setting up 3 node Kilo per installation guide for Ubuntu. Got to the part about neutron agent-list which returns nothing. Note that neutron ext-list seems to work fine.

There is an error in metadata-agent.log indicating that "neutron.agent.metadata.agent Failed reporting state!"

I have searched this error, but none of the solutions seem to apply here.

Is it an HA installation?

not HA and no, I have not installed ibaas or fwaas (following the basic 3 node configuration setup). Here is a critical error in openvswitch-agent.log. 2015-07-01 15:53:49.632 6550 CRITICAL neutron [req-1d60a592-3177-466f-95c8-cec94ff9f7eb None] No module named rabbit

I don't think the neutron node is ever getting to the controller node as I can kill rabbitmq-server on the controller and get same error. I have tried commenting out rpc_backend = rabbit which changes the error (the neutron server then tries to find the mq on local_host, which is not what I want.

WOO HOO!!!! OK, I think I see what was going on. Indeed, the rabbit module can not be found. I never figured out how to install it. So I switched to rpc_backend = neutron.openstack.common.rpc.impl_kombu. BUT, this did not work right away because when you do this, the information in [oslo_messaging_rabbit] seems to be ignored.

The solution that ultimately worked for me is to move ALL of the rabbit configuration parameters to the default section. i.e. [DEFAULT] ... rpc_backend = neutron.openstack.common.rpc.impl_kombu rabbit_host = controller rabbit_userid = openstack rabbit_password = RABBIT_PASS ... (substitute your value for RABBIT_PASS)

Note that other answers involved simply commenting out rpc_backend = rabbit or changing RABBIT_PASS back to guest guest. These worked for some because the default parameters were OK for their [single node] setup. In other words, it didn't matter that [oslo_messaging_rabbit] was being ignored - the defaults worked or these folks ended up reverting some settings to default to get things working.

I hope this helps someone else...took me DAYS to figure out.

I am getting the same issue and have tried the removing rpc_backend = rabbit; as well as trying your fix in what I assume is the network nodes neutron.conf file. nothing works, still throwing the no mudule names rabbit

Have you installed advanced services sunch as neutron-lbaas,neutron-fwaas? In kilo,these services are independent from neutron.
