Hello:

Neutron ML2/SR-IOV only supports physical networks (flat, VLAN) [1]. It is not possible to create a SR-IOV port in a tunnelled network.

Regards.

Hi there,

I think the limiting factor here is neutron does not support SRIOV
with VXLAN[1] but maybe I am wrong.

If I am wrong and you can configure neutron to use VXLAN tunnels on
SR-IOV ports (vnic_type: DIRECT), then Octavia should be able to use
it.

Maybe someone from the neutron team can also answer.
