Abstract: Techniques for dynamically using system (i.e., VM guest) memory as video memory for virtual graphics processing units (VGPUs) are provided. In one embodiment, a guest graphics driver running within a virtual machine (VM) of a host system can receive, from a guest application of the VM, a request to create a graphics resource. The guest graphics driver can then dynamically allocate, in response to the request, a memory object for the graphics resource in a guest memory space of the VM.

Abstract: Autonomous selection between multiple virtualization techniques implemented in a virtualization layer of a virtualized computer system. The virtual machine monitor implements multiple virtualization support processors that each provide for the comprehensive handling of potential virtualization exceptions. A virtual machine monitor resident virtualization selection control is operable to select between use of first and second virtualization support processors dependent on identifying a predetermined pattern of temporally local privilege dependent instructions within a portion of an instruction stream as encountered in the execution of a guest operating system.
