The version is liberty

[Jakub Libosvar (libosvar)]

Turned out to be a misconfiguration, missing qos in ml2 extensions.

[Matthias Runge (mrunge)]

missed adding the extension to ml2.

[Igor D.C. (igordcard)]

If someone's looking for the quick fix:

Edit /etc/neutron/plugins/ml2/ml2_conf.ini,
inside [ml2] edit extension_drivers to include qos.
