neutron-openvswitch-agent.service not starting [closed]
Hi, I am following a openstack liberty http://openstack-xenserver.readthedocs.io/en/latest/11-install-networking-neutron-on-compute-vm.htmll (setup document) and in compute-vm node I am unable to start neutron-openvswitch-agent.service. neutron is running fine in controller, nova is also good in both.
I am using CentOS 7 and here log:
[root@compute-vm ~]# systemctl status neutron-openvswitch-agent.service

Is openvswitch (the RPM) installed, and the openvswitch service enabled and started? What does 'ovs-vsctl show' say?
It seems that this command fails:
ovs-vsctl --timeout=10 --oneline --format=json -- --columns=ofport list Interface xapi1. You might get a useful error message by running it manually as root.Thank you very much. I am new to xen server. Please look at the output of your proposed command. I updated my question.
I am not really sure, Had I need to create bridge interface on compute-vm? My controller has eth1 as public interface which is bridged to br-eth1, no bridge in compute-vm....xen interfaces output updated in my question......please review
"I am new to xen server" Well, I am not even new to it. With that caveat, I suggest you search the config files under /etc/neutron for the string "xapi1" and try to get clues from what you find. The question is: How are Xenserver networks connected into the OVS bridge.
