Public bug reported:
When QoS floating IP is used, the OVN QoS rules do not apply to distributed
floating IP ("enable_distributed_floating_ip=True"). The condition applied in
[1]:
is_chassis_resident(chassisredirect_lrp_xxx)
is valid for non distributed floating IP deployments. The
chassisredirect lrp is present in the chassis where the floating IP NAT
is done.
But in distributed floating IP deployments, the NAT is done locally in the
compute node that hosts the private IP port; that means the match condition
should be:
is_chassis_resident(private_port)
