virtualbox.org

as per title I'm looking for benchmark comparing performance of virtualbox vs kvm vs xen.
Or maybe someone here made some test comparing latest virtuablbox against kvm or xen
I found this on the net
http://www.zdnet.com/blog/perlow/virtua ... n-71/13020
But when I tested the 2 software, I got different results, virtualbox resulted to me on an ubuntu 64 bit host much faster than vmware .
I know in theory kvm and xen are supposed to be faster than virtualbox , but i read many user complaining about slowloness of kvm.

-Also I read that is possible to use svgaII of vmware with kvm, would be possible to do the same with virtualbox since vmware direct3d it's better?

I have a machine with athlon II x4 2.7ghz, mainboard with 785g chipset(no iommu), 8gb ddr2, ati 4670 1gbddr3
I need virtualization to run 1 vm with xp for certain softwares (I would like run 3d games, but it's not essential, just a big plus), and other vm for develpment and testing mostly with windows server 2008 os and Red Hat
The host OS is Opensuse 11.3 64bit

I was just searching for information on this myself and came across this article (from this past January)
