      This is currently block by promotion of the python-os-vif package.

      it dose not seam to set up as part of the compute component so its not clear how this is currently promoted.
      until that is resolved and the back-ported content is properly built and promoted into the nova-compute container this
      blocked.

      .Enhanced `os-vif` OVS plugin improves network performance on OVS interfaces

      Previously, a bug fix was made to OVS that changed the application of the kernel's default QOS policy to OVS ports. This fix was applied to 17.1 but not to 18.0. As a result, a regression in the network configuration for OVS interfaces negatively impacted network performance of Openstack instances when using kernel OVS.
      With this update, the `os-vif` OVS plugin has been enhanced to improve network performance on OVS interfaces by using the linux-noop QOS policy by default. This can still be overridden by neutron QOS policies.
      To apply the update, restart or move the instance to recreate the port with a hard reboot, perform a detach followed by an attach operation, or perform a live migrate operation.

      To Reproduce Steps to reproduce the behavior:
      Because https://review.opendev.org/c/openstack/os-vif/+/883015 was abandoned in upstream and didn't make it to proper stable branch, we ended up without Id9ef7074634a0f23d67a4401fa8fca363b51bb43 in RHOSO 18. The customer double-checked tap interface parameters and fq_codel is back.

      Expected behavior
      Id9ef7074634a0f23d67a4401fa8fca363b51bb43 presents in RHOSO 18

      Bug impact
      Critical: performance is much lower

      Known workaround
      Manually reset things
