Preface: The intention of this bug is to provide insight into a feature proposed by Netronome for inclusion in RHOSP12. Description: 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. Status: Patches are in internal testing, RFE+patches will be submitted by 07/07 2017 to Neutron.
Were patches submitted?
(In reply to Ihar Hrachyshka from comment #1) > 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: https://review.openstack.org/#/c/483530/ 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.
