Red Hat Bugzilla – Bug 1467914
Neutron support for VNIC_VIRTIO_FORWARDER
Last modified: 2017-12-13 16:37:25 EST
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 patches are submitted at:
End-to-end testing with Nova, Neutron, OS-VIF and the external plugins have verified that these changes to core Neutron are sufficient.
The review was merged and landed in neutron-lib 1.9.0
Verified that the symbol is shipped with neutron-lib. Note that support for the new vif type is a broader request and is out of scope for this particular bug.
