Abstract

Embodiments of apparatuses, methods, and systems for processing interrupts in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes a recognition logic, window logic, and evaluation logic. The event logic is to recognize an interrupt request. The window logic is to determine whether an interrupt window is open. The evaluation logic is to determine whether to transfer control to one of at least two virtual machine monitors in response to the interrupt request if the interrupt window is open.
