Hi Jing,

To my knowledge no one has done the work to support SRIOV network
ports in Octavia load balancers. This is an open roadmap item[1].

It will require some development effort as we hot-plug the tenant
traffic ports, which means we need to give nova some hints when
booting the instances that the amphora instance will be using SRIOV.

You might be able to accomplish it on train using the flavors
capability. You would create a special nova flavor with the required
"extra_specs"[2] to schedule the instance on the proper SRIOV host
with the SRIOV libvirt settings. Then you can create an Octavia
flavor[3] that uses this special nova flavor. You could then create a
load balancer by passing in the neutron SRIOV port as the VIP port.
This would not provide a solution for adding additional SRIOV ports to
the load balancer for the member servers, but you can use the VIP port
to access members.

I have not tried this and would be interested to hear if it works for you.

If you are interested in implementing SRIOV support for Octavia,
please consider adding it to the PTG agenda[4] and joining us at the
virtual PTG.
