I'm running Ubuntu 14.04LTS with OpenStack Icehouse installed. All services appear to be running normally, and I'm able to launch instances and get IPs assigned to them. I'm able to ping instances and ping out from instances. The setup is a flat networking setup using a single NIC on eth0.

I'm getting the following repeating error in the nova-scheduler.log:

I'm also getting errors in nova-conductor.log:

hi, By observing your nova scheduler and nova conductor log file,* ERROR oslo.messaging.rpc.dispatcher* - there is a problem with client-server remote procedure calls.It may occurs when the Queue cant be able to respond all incoming requests.It will not affect you to certain extent.Simply restart the Messaging Queue (say Rabbit MQ)service and observe the log files once again..

thanks, krishnaa
