Abstract: Embodiments of apparatuses and methods for processing virtualization events in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes a hardware processor including event circuit to recognize a virtualization event, and evaluation circuit to determine whether to transfer control of the apparatus from a child guest to a parent guest in response to the virtualization event, wherein the child guest and the parent guest each include a bit per virtualization event to indicate whether the parent guest is to gain control when the virtualization event occurs.

Abstract: A method and apparatus is described herein for accessing a physical memory location referenced by a physical address with a processor. The processor fetches/receives instructions with references to virtual memory addresses and/or references to physical addresses. Translation logic translates the virtual memory addresses to physical addresses and provides the physical addresses to a common interface. Physical addressing logic decodes references to physical addresses and provides the physical addresses to a common interface based on a memory type stored by the physical addressing logic.
