They make use of the paravirtualized virtio framework which is orders of 
magnitude faster than fully virtualized i/o.

Well, somebody said use AMD cpus because they are more stable but I have

If you need performance, you need paravirtualized i/o. With a kvm 
solution, that means going through virtio. I think Xen has its own 
solution to this and other than this, I know nothing about vmware and 
virtualbox on this score.
