[fedora-virt] Update on virtio network driver performance

[Paul Lambert]

Just some feedback for Rich on performance after switching to virtio 
network driver.

Before both cpus were running at 70-90%.  After virtio driver cpus 
running 20-30%.  That's something like 67% less loading.  The real test 
is whether the keyboard, mouse and window dragging "shadow" or delay 
when moving.  This is much better but not equal to that of performing 
these functions on the host machine.

OK, so where's the virtio drivers for Windows?  I found a link dated 
early March that stated they were coming soon.   Can't find them anywhere.
