Hello,
On the compute node (IP addr : 10.176.20.4) I am seeing the following
error message in /var/log/nova/nova-compute.log:

The rabbitmq server is running on the controller node (10.176.20.158),
which is reachable from the compute node. Can someone please help me
understand why the compute node is trying to connect to AMQP server on
localhost.
