Displaying graphics for local virtual machine by allocating and mapping textual buffer

Abstract:

A computing device for displaying images includes one or more processors to obtain graphical data that has been generated by one or more applications associated with a first virtual machine, and to map one or more virtual apertures or one or more actual buffers associated with the first virtual machine to a textual buffer associated with a second virtual machine, and process the graphical data based on the mapping. The virtual apertures are in a virtual memory space and the actual buffers being in a physical memory space. The graphical data includes rendered composite graphical data representing a desktop and one or more application windows. The one or more processors allocate physical memory space in the textual buffer associated with the second virtual machine to support the mapping. A display device displays images using the processed graphical data.
