I'm having some trouble with nova-compute. I'm installing openstack multi node with four servers and I can't get nova-compute listed in nova services,

Controller node

root@nimbo1:~# nova-manage service list
Binary           Host                    Zone             Status     State  Updated_At
nova-scheduler  nimbo1   internal         enabled    :-)      2013-10-04 00:17:37 
nova-conductor   nimbo1 internal         enabled    :-)      2013-10-04 00:17:41 
nova-cert nimbo1    internal         enabled    :-)     2013-10-04 00:17:41 
nova-consoleauth nimbo1   internal         enabled    :-)     2013-10-04 00:17:37

As u see, there is not nova-compute of the compute nodes. When I try to start manuall, nova-compute, there is an error that appears in both compute nodes,

Hi, is nova-manage service-list looking at locally running processes or will it look into service and enpoint registration in keystone? Maybe you have to look there! The UnsupportedRpcVersion exception I can see above makes me think you should double check URLs in your endpoint registrations. Just a though...
