If the plugin does not support the extension it will never be loaded.
The supported extensions are see decanted in the
supoorted_extendion_aliases. Rather than develop your own OVS QoS
plugin I'd recommend you contact the assignee of the h3 blueprint who is
building an ext for he community.

Title:
Neutron cannot load extension
Status in OpenStack Neutron (virtual network service):
Invalid
Bug description:
I have a demand to develop QoS for OVS Plugin. So, I put the ‘Qos.py’ in the
'/neutron/plugins/openvswitch/extensions' and set 'api_extensions_path =
/neutron/plugins/openvswitch/extensions' in 'api-paste.ini'.
But it can not be loaded. I traced the loading process, I found the path
could not be recognized by 'os.path.exists()'.
In file 'neutron/api/extensions.py', I find the code:
def get_extensions_path():
paths = ':'.join(neutron.extensions.__path__)
if cfg.CONF.api_extensions_path:
paths = ':'.join([cfg.CONF.api_extensions_path, paths])
return paths
According to the codes, i must configure absolute path, such as
"api_extensions_path = /usr/lib/python2.7/dist-
packages/neutron/plugins/openvswitch/extensions". However, it think
it's complicated.
I have changed the codes to add the prefix path to 'api_extensions_path':
def get_extensions_path():
#spch
paths = ':'.join(quantum.extensions.__path__)
#get the prefix path
prefix = "/".join(quantum.__path__[0].split("/")[:-1])
if cfg.CONF.api_extensions_path:
#split the api_extensions_path by ":"
ext_paths = cfg.CONF.api_extensions_path.split(":")
#add prefix for each path
for i in range(len(ext_paths)):
ext_paths[i] = prefix + ext_paths[i]
ext_paths.append(paths)
paths = ":".join(ext_paths)
return paths
I do not know whether it's a bug or i do not understand the question.
So, please help me.
