That's a good idea, but yes, it depends rather heavily on whether the
VM will run things like the vendor specific video drivers
(ie. NVidia and ATI binary drivers). I'll take a look
into it.

No, sadly, it won't - the VM provides emulated graphics hardware, and a driver for it that the guest OS uses.

Right, the VM just emulates a standard VESA card (which isn't too fast), and additionally/alternatively provides optimized proprietary graphics drivers which can be installed in the guest operating systems (Windows driver, driver for the Xorg/Xfree86 server, ...), which bypass the hardware emulation in order to achieve fast graphics output.

USB or serial port also may not be elulated sufficiently. During an evaluation I encountered an USB device which did not work if attached to the VM, and Spectrocam (via serial port) also failed in a VM running Windows (though both worked natively).
