Abstract: Apparatus and method for implementing a virtual display. For example, one embodiment of a graphics processing apparatus comprises at least one configuration register to store framebuffer descriptor information for a first guest running on a first virtual machine (VM) in a virtualized execution environment of a host processor, the framebuffer descriptor information to indicate one or more display pipes assigned to the first guest; and execution circuitry to execute a first driver assigned to the first guest, the first guest to use the first driver to display a framebuffer in a plane associated with one of the display pipes in accordance with the framebuffer descriptor information.
