commit 559ae06bdf1f11ca861234a92434771a26ec27d8 Author: Frode Nordahl <[email protected]> Date: Thu Jun 4 10:35:50 2020 +0200 [OVN] Override notify_nova config in neutron-ovn-db-sync-util If either ``notify_nova_on_port_status_changes`` or ``notify_nova_on_port_data_changes`` is set in the neutron configuration provided to the ``neutron-ovn-db-sync-util`` tool it will stop with a Traceback. We are already overriding other parts of the ML2 Notification code as we do not want it executing while syncing, so let's override these configuration options if set as well. Change-Id: I62765a14d376664ccc2ca3009bb9e970c9f25c03 Closes-Bug: #1882020 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1882020 Title: neutron-ovn-db-sync-util fails with Traceback when notify_nova config is present Status in neutron: Fix Released Bug description: If either ``notify_nova_on_port_status_changes`` or ``notify_nova_on_port_data_changes`` is set in the neutron configuration provided to the ``neutron-ovn-db-sync-util`` tool it will stop with the following Traceback on startup: neutron-ovn-db-sync-util --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini 2020-06-03 13:12:17.066
