Abstract:
Embodiments of apparatuses, methods, and systems for processing virtual interrupts in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes virtual machine entry logic, recognition logic, and evaluation logic. The virtual machine entry logic is to transfer control of the apparatus from a host to a guest. The recognition logic is to recognize a virtual interrupt request. The evaluation logic is to determine whether to transfer control from the guest to an intervening monitor in response to the virtual interrupt request.
