Draknem :
Is there any program that would allow running mustiple os es on a pc (something like vmware vSphere) but capable of using gpu acceleration of a pc it runs on and showing desktops on the monitors attached? So I can run windows and linux simultaneously, not running one inside another.
sorry for my bad english
VMWare VSphere Hypervisor is a free version of VMWare VSphere. Since it's a bare-metal hypervisor (as opposed to one that runs on top of an operating system such as Windows) it comes with its own drivers. Driver support is not as extensive as most consumer operating systems, and legacy support is hit and miss. You should check and see if your hardware is supported before installing it.
EDIT: As a side note, VMWare Workstation (not free, but much cheaper than commercial versions of VMWare VSphere) does support a limited amount of pass-through hardware acceleration. I believe that it currently works quite nicely with OpenGL 2.1 and DirectX 9.0c.
