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.

Virtualization event processing in a layered virtualization architecture

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.

Accessing physical memory from a CPU or processing element in a high performance manner

Embodiments of apparatuses and methods for processing virtualization events in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes a event logic and evaluation logic. The event logic is to recognize a virtualization event. The evaluation logic is to determine whether to transfer control from a child guest to a parent guest in response to the virtualization event.

Virtualization event processing in a layered virtualization architecuture

A platform and method for secure handling of events in an isolated environment. A processor executing in isolated execution 'IsoX' mode may leak data when an event occurs as a result of the event being handled in a traditional manner based on the exception vector. By defining a class of events to be handled in IsoX mode, and switching between a normal memory map and an IsoX memory map dynamically in response to receipt of an event of the class, data security may be maintained in the face of such events.

Mechanism to handle events in a machine with isolated execution

In one embodiment, a predefined behavior of a virtual machine monitor (VMM) with respect to one or more virtual machines (VMs) is identified, and processor-managed resources associated with the one or more VMs are utilized based on the predefined behavior of the VMM.

Optimizing processor-managed resources based on the behavior of a virtual machine monitor

Embodiments of apparatuses, methods, and systems for controlling virtual machines based on activity state are disclosed. In one embodiment, an apparatus includes virtual machine entry logic and activity state evaluation logic. The virtual machine entry logic is to transfer control of the apparatus from a host to a guest. The activity state evaluation logic is to determine whether the activity state of the guest would be inactive upon receiving control.
