Bug Description

I install openstack essex with source code on CentOS 6.2. I run keystone, glance-api, glance-registry, nova-api, nova-network, nova-scheduler, nova-cert, nova-objectstore and nova-compute on my control node and only nova-compute on a compute node.

I can suspend and pause a instance on control node with command "nova suspend servername" and "nova pause servername". But I can only pause a instance on my compute node. If I use command "nova suspend servername" to suspend a instance on compute node I will get a error message as below:

This looks more like a libvirt bug not a nova bug. Due to the following error message:

internal error unable to send file handle 'migrate': No file descriptor supplied via SCM_RIGHTS
