I am trying to build VlanManager environment with OpenStack grizzly on Cent OS 6.4, but it doesn't work. I am using all-in-one architecture (single-host). FlatDHCPManager successfully worked.

VM couldn't get IP address. VM creation failed with the below logs of /var/log/nova/compute.log, even though I increased the RPC response timer. I am assuming that message exchange between nova and nova-network failed due to the defect of amqp or something.

 5290 TRACE nova.openstack.common.rpc.amqp raise rpc_common.Timeout() 
 5290 TRACE nova.openstack.common.rpc.amqp Timeout: Timeout while waiting on RPC response. 
 5290 TRACE nova.openstack.common.rpc.amqp

So, I am assuming that there is any bug/defect that VlanManager can't work with single-host architecture. Does anyone know if there is such a bug related to VlanManager on single-host architecture?

What's your mean of does not work? Can you check whether vm has got an IP ? Or if it got one, you can check your tap device's tag number.

If you use cirros, you can use "nova console-log" to see the boot console log where you can check whether it got ip. And use "ovs-vsctl show" to show the tag number, but the premise is that you used the openvswitch.

I meet many network troubles in distributed env, and this link is helpful for me. http://docs.openstack.org/trunk/openstack-ops/content/network_troubleshooting.html
