Thank you for your input on 3D acceleration virtualization.

1- I hope some day you may post some links about what you are talking about,

I don't use vmware. I used it a few years ago, nowadays I use libvirt.
Any how, here are 2 links about vmware workstation 5.5 and vmplayer

http://www.vmware.com/support/ws55/doc/ws_vidsound_d3d_enabling_vm.html

and a video showing benchmarks with 3DMark 2001 on a XP client 800x600 16 bits

2- I don't know what is your problem on understanding that a computer
running a host and a hypervisor and the client will be slower than the
client running natively.

Even if the virtualised drivers are better, the client will still run
his drivers on top, so I must be missing something here, and I will
appreciate your help.

3- About libvirt and virtualbox
"KVM can handle PCI passthrough as well as direct access to the USB
bus, however, a feature that remains unimplemented in VirtualBox."
"VirtualBox in principle offers such support, although in practice it
doesn’t always work well.  KVM currently lacks 3D-acceleration
support"
