I'm currently setting up a testlab with Ubuntu 14.04 and the RC1 of Icehouse. I have 3 nodes (controller, compute, network) and the controller and compute node run fine so far. On the network node I run into a problem with OVS. As soon as the machine comes up it goes to 100% CPU and syslog keeps repeating:

Apr  8 13:02:13 network ovs-vsctl: ovs|00001|vsctl|INFO|Called as /usr/bin/ovs-vsctl --timeout=10 -- --if-exists del-port br-int patch-tun
Apr  8 13:02:14 network ovs-vsctl: ovs|00001|vsctl|INFO|Called as /usr/bin/ovs-vsctl --timeout=10 -- --if-exists del-port br-int patch-tun

Some info on the setup: ovs_neutron_plugin.ini

[DATABASE]
sql_connection = mysql://XXX:XXX@172.16.0.200/neutron


[OVS]

The whole thing seems related to https://ask.openstack.org/en/question/1427/ovs-plugin-error-failed-to-create-ovs-patch-port/ but I think it is different enough to be a new question because it's 14.04 and OVS 2.0.1

It would be great if someone could point to a solution.
