Description Nir Yechiel 2015-09-24 13:26:55 UTC

Description of problem:

As described in [1], a new Neutron QoS feature is introduced with RHEL OSP 8. We need to make sure several configuration changes are applied by default from director to make sure the feature is usable.

Comment 3 Miguel Angel Ajo 2015-09-30 12:01:57 UTC

notes: 

for controller, I mean "where neutron-server runs"
for networker, I mean, "where the neutron-l3-agent and dhcp agents run"
for compute, I mean, "where nova compute runs".

Sorry for the excessive details, but I'm still unfamiliar about how OSPd deploys.


So, 

in the compute and networker nodes:
  * /etc/neutron/plugins/ml2/openvswitch_agent.ini
     [agent]
     extensions = qos

  
  If SR-IOV is enabled:
      * /etc/neutron/plugins/ml2/sriov_agent.ini
      [agent]
      extensions = qos

in the controller node (could be in the same host as the networker):
  * /etc/neutron/neutron.conf       
    [DEFAULT]
    add "qos" to the comma separated list of service_plugins option. There generally we have router, firewall, lbaas, etc... (add qos).

  * /etc/neutron/plugins/ml2/ml2_conf.ini
     [ml2]
      extension_drivers = qos # here we generally have port_security too "port_security, qos"

@ihar, could you help me review what I'm saying here ^  ?

Thanks,
Miguel Ángel.

Comment 4 Ihar Hrachyshka 2015-09-30 12:06:05 UTC

All said in comment #3 is correct. I would only avoid referring to nodes but instead talk about services, but that's just a stylistic thing for better understanding.

The bug moved to QA but it's not clear whether all the pieces have been merged.
