libvirt: virtio-net multiqueue (partial)
Add supoort to enable the virtio-net multiqueue feature for guest
instances.
With virtio-net multiqueue enabled network performance can be scaled
accross number of vCPUs, by transfering the packets through multiple virtqueue
pairs at a time.
Libvirt driver will set the number of queues equal to the number of guest VCPUs
To control this feature, the following should be set in the flavour extra specs:
hw:
This setting can be overriden by the image metadata property if the feature
is enabled in the extra specs:
hw_

Do you have all the code up for review? I am afraid its not totally clear to me from the current state. --johnthetubaguy 15th July 2015

I am going to mark this as partial, and having all the code up for review. Seems like there is enough up for review for this to be useful now. --johnthetubaguy 16th July 2015
