ABSTRACT:
A computing device has a hardware device employed to provide a hardware service to the computing device and a plurality of virtual machines including a host virtual machine (VM-H) to which the hardware device is assigned, and a client virtual machine (VM-C) that can consume the hardware service by way of the VM-H. The VM-C includes an emulating stack and an enlightened stack. The emulating stack interfaces an application requesting the hardware service with a trap in a virtualization layer of the computing device which re-directs the request to the VM-H. The enlightened stack interfaces the application with the VM-H and bypasses the virtualization layer. The emulating stack includes a shunt driver that shunts to the enlightened stack each request from the application directed to the emulating stack.
