Hi,

I am learning the existing Neutron code (Juno) and am going to add a ML2
driver. I can see the following debug info in neutron.log:





*2015-04-18 23:21:13.729 11068 DEBUG stevedore.extension [-] found
extension EntryPoint.parse('hyperv =
neutron.plugins.ml2.drivers.mech_hyperv:HypervMechanismDriver')
_load_plugins
/usr/lib/python2.7/site-packages/stevedore/extension.py:1562015-04-18
23:21:13.729 11068 DEBUG stevedore.extension [-] found extension
EntryPoint.parse('l2population =
neutron.plugins.ml2.drivers.l2pop.mech_driver:L2populationMechanismDriver')
_load_plugins
/usr/lib/python2.7/site-packages/stevedore/extension.py:1562015-04-18
23:21:13.729 11068 DEBUG stevedore.extension [-] found extension
EntryPoint.parse('cisco_apic =
neutron.plugins.ml2.drivers.cisco.apic.mechanism_apic:APICMechanismDriver')
_load_plugins

EntryPoint.parse('arista =
neutron.plugins.ml2.drivers.arista.mechanism_arista:AristaDriver')
_load_plugins
/usr/lib/python2.7/site-packages/stevedore/extension.py:156...( Click

)*

>From the above log we can see, neutron.plugins.ml2.managers can find all
driver extensions e.g. hyperv, l2population etc, as my understanding, there
should exist a driver list on somewhere. If I am right, where can I find
the driver list? If not, can someone give me a clue?

Any help will be much appreciated.

Thanks,
Sam
