Abstract
The present disclosure is directed towards methods and systems for maintaining state in a virtual machine when disconnected from graphics hardware. The virtual machine is one of a plurality of virtual machines hosted by a hypervisor executing on a computing device. A control virtual machine may be hosted by a hypervisor executing on a computing device. The control virtual machine may store state information of a graphics processing unit (GPU) of the computing device. The GPU may render an image from a first virtual machine. The control virtual machine may remove, from the first virtual machine, access to the GPU. The control virtual machine may redirect the first virtual machine to a GPU emulation program. The GPU emulation program may render the image from the first virtual machine using at least a portion of the stored state information.
