[Bug 1262616] [NEW] 'Multiple plugins for service %s were configured', 'L3_ROUTER_NAT'

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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:
