Icehouse Neutron OVS plug-in never take effect

[LIU Yulong]

The Icehouse neutron Open vSwitch (OVS) plug-in will always use the /etc/neutron/plugins/ml2/ml2_conf.ini as it's config-file.

http://docs.openstack.org/icehouse/install-guide/install/apt/content/neutron-controller-node.html

Some steps:
1.apt-get install python-software-properties
 add-apt-repository cloud-archive:icehouse

2.apt-get install neutron-server

3.apt-get install neutron-plugin-openvswitch

4.set core plugin
/etc/neutron/neutron.conf
core_plugin = neutron.plugins.openvswitch.ovs_neutron_plugin.OVSNeutronPluginV2

service neutron-server restart

And then the Neutron server never create the folder and OVS config-file like this:
/etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini.

It still use the /etc/neutron/plugins/ml2/ml2_conf.ini config-file.

This issue is same on compute node and network node.

FWIW, I cannot quickly reproduce this on a F20 box.:

1. save all conf files in /etc/neutron/* to TEMP directory
2. yum install openstack-neutron openstack-neutron-openvswitch

config files created in the right places. Really this may be a packaging issue?

[Marios Andreou (marios-b)]

Also I may have misunderstood your comment but the neutron-server service won't be creating the config file - this should be done when the package is installed.
