[Yoshihiro Kaneko]

I ran devstack with neutron.
And neutron net-create failed.

The cause is the default configuration value in etc/neutron.conf:

notification_driver = quantum.openstack.common.notifier.rpc_notifier

I changed 'quantum' to 'neutron', then this problem was solved.

This problem has not been solved yet.
I got the same error.

In neutron-server case, modernize_quantum_config() is called before notification_driver is registered.

can u try the patch: https://review.openstack.org/#/c/36931/?, if it can fix your problem, i will upgrade the patch's bug level.

[Yoshihiro Kaneko (ykaneko0929)]

I confirmed that your patch fixed this problem.
devstack was able to create the private network of the demo tenant.
I saw also the warning message:
  WARNING neutron.common.legacy [-] Old class module path in use. Please change
  'quantum.openstack.common.notifier.rpc_notifier' to 'neutron.openstack.common.notifier.rpc_notifier'.
thanks!
