could not add computeNode

 I like to add a compute node to openstack cloud, but nova-manage service list does work, any one can help me? Thanks!

I install openstack on two kvm guest installed ubuntu12.04 with devstack

And I want to use one node as nova controller, the other as compute node, so I copied the nova.conf of the first to the later.

But nova-manage service list seems this configuration does not take effect.
