L3RouterPlugin service plugin should be configured for plugins that
delegate away L3 routing functionality. OVSNeutronPluginV2 implements l3
functionality itself. So clearing service_plugins option should solve
the issue. Putting to invalid.

Title:
'Multiple plugins for service %s were configured', 'L3_ROUTER_NAT'
Status in OpenStack Neutron (virtual network service):
Invalid
Bug description:
When installing havan on debian 64bit wheezy, using the repositories:
deb http://havana.pkgs.enovance.com/debian havana main
deb http://archive.gplhost.com/debian havana-backports main
The neutron-server fails to start because of this check in
https://github.com/openstack/neutron/blob/master/neutron/manager.py#L174
Why raise an exception and not simply do the following:
if plugin_inst.get_plugin_type() not in self.service_plugins:
self.service_plugins[plugin_inst.get_plugin_type()] =
plugin_inst
With the existing code I can not make neutron-server run no matter, what I do.
The error is:
