My controller is an independent node, and not on the 10.10.10.x network (following this architecture<http://docs.openstack.org/folsom/basic-install/content/basic-install_requirements.html>although I have changed the external subnets). > One could suggest to restart nova-compute and check. > I tried, and it did nothing. I think something else might be going on...I do seem to be getting the correct ARP entries for 10.5.5.5 on my network node: root@os-network:/var/log/quantum# arp -an ?

There were 4 pings from 10.5.5.7 (starting line 47), followed by 4 pings from 10.5.5.5. Interesting to see the 10.5.5.3 and .4 references...I don't have passwords for those images (sshed in with the keys), so I rebooted them while sniffing here: http://pastebin.com/xpbgnhxu The network node ARP table never populated with .3 or .4, either. It looks like quantum-openvswitch-agent is started: root@os-compute-01:~# ps -ef | egrep quantum | egrep -v grep quantum 11504 1 1 09:27 ? 00:01:44 python /usr/bin/quantum-openvswitch-agent --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini --log-file=/var/log/quantum/openvswitch-agent.log root@os-compute-01:~#
