Yes, looks like stevedore version is the issue.

Can I ask a little more about what is stevedore used for ??

Thanks.

Bug description:
  Hi list,
  I'm working under CentOS 6.4 + Havana:
  openstack-neutron.noarch                                                   2013.2.1-1.el6  @openstack-havana
  openstack-neutron-linuxbridge.noarch                       2013.2.1-1.el6  @openstack-havana
  openstack-neutron-ml2.noarch                                         2013.2.1-1.el6  @openstack-havana
  openstack-neutron-openvswitch.noarch                    2013.2.1-1.el6  @openstack-havana
  python-neutron.noarch                                                           2013.2.1-1.el6  @openstack-havana
  python-neutronclient.noarch                                              2.3.1-1.el6     @openstack-havana

  
  Everything works when I was working under core_plugin = neutron.plugins.openvswitch.ovs_neutron_plugin.OVSNeutronPluginV2.

  
  While after I set           core_plugin = neutron.plugins.ml2.plugin.Ml2Plugin,
  I can't start neutron-server.

  The log in /var/log/neutron/server.log is :
