Hi again! Do you know how to debug ML2 extension drivers? I created folder with two python files: vpc/extensions/vpc.py and vpc/plugins/ml2/drivers/vpc.py (also empty __init__.py files) I added to neuron.conf api_extensions_path = /path/to/vpc/extensions and I added to ml2_ini.conf extension_drivers = port_security, vpc.plugins.ml2.drivers.vpc:VpcExtensionDriver and my neutron.server.log has: INFO neutron.plugins.ml2.managers [-] Configured extension driver names: ['port_security', 'vpc_neutron.plugins.ml2.drivers.vpc:VpcExtensionDriver'] WARNING stevedore.named [-] Could not load vpc_neutron.plugins.ml2.drivers.vpc:VpcExtensionDriver .... INFO neutron.api.extensions [req-fd226631-b0cd-4ff8-956b-9470e7f26ebe - - - - -] Extension vpc_extension not supported by any of loaded plugins How can I find why the extension driver could not be loaded?
Hi,The fake_extension is used only in unit tests to test the extension framework, i.e. : https://opendev.org/openstack/neutron/src/branch/master/neutron/tests/unit/p...
If you would like to write an API extension check neutron-lib/api/definitions/ (and you can find the extensions "counterpart" under neutron/extensions in neutron repository)
You can also check other Networking projects like networking-bgvpn, neutron-dynamic-routing to have examples of API extensions. If you have an extension under neutron/extensions and there's somebody who uses it (see [1]) you will see it is loaded in neutron servers logs (something like this: "Loaded extension: address-group") and you can find it in the output of openstack extension list --network

Hi all!
Sorry for a complete noob question but I can't figure it out 😿
So if I want to add Fake ML2 extension what should I do?
I have neutron server installed and I have the file: https://github.com/openstack/neutron/blob/master/neutron/tests/unit/plugins/...
How to configure neutron server, where should I put the file, should I create another files? How can I test that it works?
