[OVN] neutron-ovn-db-sync-util fails without qos extension driver

[Jake Yip]

Running neutron-ovn-db-sync-util with the following `extension_drivers=port_security` fails with

I tracked it down to https://opendev.org/openstack/neutron/src/commit/429fbae1d0e835f7282040f59a71c2fcb9fa7a7d/neutron/cmd/ovn/neutron_ovn_db_sync_util.py#L203 where qos is added to `conf.service_plugins` regardless whether I have qos in my deployment.

Status changed to 'Confirmed' because the bug affects multiple users.

[olmy0414 (oleksandr-mykhalskyi)]

I have the same issue, after updating from wallaby to xena

[Jake Yip (waipengyip)]

I had a change https://review.opendev.org/c/openstack/neutron/+/855668 but didn't manage to pass CI.

I might give it a go again when I get a free moment. Can you confirm that patch worked for you?

    Enable qos extension_driver in ovn_db_sync

    In Change Ib597b62017b56b41009dd4d7359e169f424272b0, the 'qos'
    service_plugin is enabled when doing an ovn_db_sync. However, if the
    'qos' extension_driver is not installed, it will error out.

    Append 'qos' extension_driver when using sync to fix this issue.
