### A bug on OpenStack

Hi OpenStack experts,

Could you please, help me out on this? I need your experts advice. 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.

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?

Any pointer or letting me know anyone who is familiar with this would be highly appreciated. Thank you so much in advance,

Bird Kafka

### A bug Timeout while waiting on OpenStackRPC response

Hi OpenStack experts,

Could you please, help me out on this? I need your experts advice. 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?

Any pointer or letting me know anyone who is familiar with this would be highly appreciated. Thank you so much in advance,
