Abstract: A method is provided for sharing access to graphics processing unit (GPU) hardware between multiple client virtual machines, wherein each of the client virtual machines has a high-level application programming interface (API) associated therewith for communicating with the GPU hardware. The method includes virtualizing the GPU by intercepting GPU-specific commands from the plurality of client virtual machines, wherein the commands specific to the GPU are at a lower level than that of the high-level API, and providing the intercepted commands to the GPU hardware.

Abstract: Methods and apparatus for sharing a physical device and/or service between multiple virtual and/or physical machines are disclosed. In an embodiment, a hypervisor grants permission to a first virtual machine to access a physical device via the hypervisor. For example, the hypervisor may grant permission to a first virtual machine to access a physical audio device. A second virtual machine then accesses the physical device via the hypervisor and the first virtual machine using a virtual services network stack. For example, the second virtual machine may play music on the audio device via the first virtual machine. In another embodiment, a first physical machine is granted permission to access and/or is connected to a physical device (e.g., an audio device) via a communication channel. A second physical machine then accesses the physical device (e.g., plays music) via the communication channel and the first physical machine using the virtual services network stack.
