    Change QoS configuration manual
    
    As [1] shows, the controller node hosts the Neutron server but
    also agents like L3 and DHCP which require also OVS or LinuxBridge
    agent to be running on it.
    To enable QoS is required to enable the 'service_plugins' and
    the 'extension_drivers', along with the agent section in the plugin
    config if the agent is running on this host.
    
    In the network node and the compute node only the agent
    'extensions' configuration is needed to enable QoS
    on the agent.

Title:
  Quality of Service (QoS) , document is critical error

Status in neutron:
  Fix Released

Bug description:
  Configuration in network node and compute node is wrong ,

  -----------------------------------------------------------------------------
  must comfiguration in controller node

  @controller node : /etc/neutron/neutron.conf
  service_plugins = router,qos

  @controller node : /etc/neutron/plugin.ini
  [ml2]
  extension_drivers = port_security,qos

  -----------------------------------------------------------------------------
  then configure in network node :
  /etc/neutron/plugins/ml2/openvswitch_agent.ini
  [agent]
  extensions = qos

  -----------------------------------------------------------------------------
  last configure in compute node :

  /etc/neutron/plugins/ml2/openvswitch_agent.ini
  [agent]
  extensions = qos

  -----------------------------------------------------------------------------

  otherwise ,
  you will always get error such as follow:
