I have setup the 3-node neutron architecture on CentOS according to the openstack install instructions. 1 controller, 1 neutron node and 2 compute nodes.

The problem I am having is the instance is stuck in the BUILD, an empty Task State, and Power State of NOSTATE. While attempting to diagnose the problem I started the neutron-dhcp-agent on the CONTROLLER node, and my instance is now successfully able to go ACTIVE and Running. The problem is, neutron-dhcp-agent is already running on my Network node......

Does anyone have any idea where to look to figure out the problem? The instructions state to setup neutron-dhcp-agent on the Network node. It is successfully running on the Network node. There are no errors except on the compute node in /var/log/libvirtd/libvirtd.log : 6815: error : virNetSocketReadWire:1194 : End of file while reading data: Input/output error

Everything is working, but why is it trying to use the neutron-dhcp-agent service on my controller? I also no longer see any new errors in libvirtd.log related to the EOF.

I've checked my configuration several times, and haven't been able to find any difference between that and the Icehouse install guide.

Any ideas on where I can look to diagnose the problem or what it could be? What are the ramifications if I leave the neutron-dhcp-agent running on my controller node? (TBH I'd rather have both the controller and neutron on one machine, so I can use the other machine I have now thats running neutron to also run a controller for redundancy...).

(I installed using SaltStack automation, so I know I didn't fat finger anything, or install something on the wrong box)
