Description Jan Gutter (Netronome) 2017-07-05 13:41:29 UTC 
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.
Comment 1 Ihar Hrachyshka 2017-07-11 14:05:33 UTC 
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.
Comment 3 Jan Gutter (Netronome) 2017-07-20 10:19:15 UTC 
The review was merged and landed in neutron-lib 1.9.0
Comment 6 Ihar Hrachyshka 2017-11-06 21:57:10 UTC 
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.
