Hi,

I would like to request FFE for vhostuser vif driver.

2 reviews : https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/libvirt-vif-vhost-user,n,z

BP: https://blueprints.launchpad.net/nova/+spec/libvirt-vif-vhost-user
Spec: https://review.openstack.org/138736

Blueprint was approved but it's status was changed because of FF.
Vhostuser is a Qemu feature that allows fastpath into the VM for userspace vSwitches.
The changes are small and mostly contained to libvirt driver.
Vhostuser support was proposed for Juno by Snabb switch guys but didn't make it,
this implementation supports their usecase as well .

Thanks
Przemek
