virtualizing...

Thanks Bill,

My home system is a core 2 quad Q9550. I believe it has the features 
needed to support full virtualization. (vmx)

The bit which puzzles me, is how do the virtual machine share the 
graphics adapter? Is there some kind of virtual adaptor which which 
multiplexes down to the physical adapter? Or are the virtual systems 
running in a console-less mode and direct their output to some virtual 
serial port?
