Neutronclient support for VNIC_VIRTIO_FORWARDER
Last modified: 2017-07-26 12:26:48 EDT
The intention of this bug is to provide insight into a feature proposed by Netronome for inclusion in RHOSP12.
Work is underway to extend the list of supported VNIC types in OpenStack in order to support a lightweight VF-to-vhostuser virtio proxy. This mechanism would allow a VM to boot with a vhostuser interface where the proxy on the hypervisor does not itself to complex switching.
The key difference between standard vhostuser plugs is that VNIC_VIRTIO_FORWARDER will consume a VF resource.
This provides another plugging method into accelerated and offloaded NICs.
Patches are in internal testing, RFE+patches will be submitted by 07/07 2017 to Neutron.
Were patches submitted?

> Were patches submitted?
Apologies, late in the dev cycle it was discovered that a new VIF type would be required, the changes to python-neutronclient and python-openstackclient remained the same, however. The patches are submitted at:
The patches to python-openstackclient were accepted, but since python-neutronclient has been frozen and deprecated since Ocata, it might not be merged there. This does not block support in Horizon, however.
The change to python-neutronclient was abandoned due to the freeze.
Closing the bug as WONTFIX since it does conflict with upstream plans for neutronclient. No major product/integration issues are expected from the upstream decision.
