Hi Anthony

Here is one I made as I went along.  If it's useful I will move it to 
the KVM wiki.  VirtIO does seem to improve performance of an openGL 
video game ("enemy territory" used in the paper).  However glxgears gets 
better performance (more FPS) using rtl8139.  Perhaps a bandwidth v. 
latency difference?
