Hi. I've been following the OpenStack Installation Guide for Red Hat Enterprise Linux, CentOS, and Fedora ( http://docs.openstack.org/trunk/install-guide/install/yum/content/ (http://docs.openstack.org/trunk/insta...) ) to make a 3-node deployment (i.e., controller, network and compute) of OpenStack Icehouse in CentOS 6.4.

All services are installed in their respective nodes and appear to be functioning. However, the service nova-compute in the compute node fails to connect to the service nova-conductor in the controller node (though both services are effectively connected to the message server, qpid , running in the controller node).

The following is a snippet of /var/log/nova/compute.log after restarting the service nova-compute in the compute node:

Any assistance (or suggestion) would be appreciated. I can provide any additional information that would help troubleshoot the issue.

Thanks.

UPDATE:

• I'm running CentOS 6.4 in all three nodes.
• I'm trying to deploy OpenStack Icehouse.
