Hi kakuma, Thank you very much for the advice.

Surely ofagent is already running when the system boots, which is confirmed by the service command. And the application could not run because port number 6633 is already used by ofagent. When I modify OFP_TCP_PORT written in /usr/local/lib/python2.7/dist-packages/ryu/ofproto/ofproto_common.py from 6633 to another value, the error disappears. # Is there any better way rather than modifying ofproto_common.py? # This file seems to be read by both ofagent and ryu application, so # when ofagent is rebooted, it also uses the new value for OFP_TCP_PORT. Anyway, even though the port number error is resolved, the application still cannot connect to Open vSwitch in compute node. I have checked /var/log/neutron/openvswitch-agent.log and it says as follows. ---------------------------------------------------- ...................... 2015-05-01 04:50:16.879 1639 INFO oslo.messaging._drivers.impl_rabbit [req-67c50a56-64cd-4308-8f56-ee96abaa88a4 ] Connected to AMQP server on controller:5672 2015-05-01 04:50:16.890 1639 INFO neutron.plugins.openvswitch.agent.ovs_neutron_agent [req-67c50a56-64cd-4308-8f56-ee96abaa88a4 None] Agent initialized successfully, now running... 2015-05-01 04:50:16.892 1639 INFO neutron.plugins.openvswitch.agent.ovs_neutron_agent [req-67c50a56-64cd-4308-8f56-ee96abaa88a4 None] Agent out of sync with plugin! 2015-05-01 04:50:16.942 1639 INFO neutron.plugins.openvswitch.agent.ovs_neutron_agent [req-67c50a56-64cd-4308-8f56-ee96abaa88a4 None] Agent tunnel out of sync with plugin! ---------------------------------------------------- Although ofagent is running, it seems not to work properly. Is this a problem about ofagent settings?

I appreciate if you have some advices.
