OVN mech driver - can't find Logical_Router errors

[Slawek Kaplonski]

I saw such errors in the CI job's logs.

Traceback:

This test hasn't failed in the last week and has passed 171 times during that time http://status.openstack.org/openstack-health/#/test/neutron_tempest_plugin.scenario.test_qos.QoSTest.test_create_instance_using_network_with_existing_policy

It fails consistently on the patch, but looks like it passes elsewhere. Rodolfo has some comments he would like addressed on the patch itself. It looks like either the patch itself is causing the issue or maybe it has been fixed and the patch should be rebased.

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/neutron 18.0.0.0rc1 release candidate.
