A processor including logic to execute an instruction to synchronize a mapping from a physical address of a guest of a virtualization based system (guest physical address) to a physical address of the host of the virtualization based system (host physical address), and stored in a translation lookaside buffer (TLB), with a corresponding mapping stored in an extended paging table (EPT) of the virtualization based system.

Synchronizing a translation lookaside buffer with an extended paging table

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 processor including a virtualization system of the processor with a memory virtualization support system to map a reference to guest-physical memory made by guest software executable on a virtual machine which in turn is executable on a host machine in which the processor is operable to a reference to host-physical memory of the host machine.

Virtualizing physical memory in a virtual machine system using a hierarchy of extended page tables to translate guest-physical addresses to host-physical addresses

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 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.

Embodiments of apparatuses, methods, and systems for delivering an interrupt to a virtual processor are disclosed. In one embodiment, an apparatus includes an interface to receive an interrupt request, delivery logic, and exit logic. The delivery logic is to determine, based on an attribute of the interrupt request, whether the interrupt request is to be delivered to the virtual processor. The exit logic is to transfer control to a host if the delivery logic determines that the interrupt request is not to be delivered to the virtual processor.

Delivering interrupts directly to a virtual processor

According to an embodiment of the invention, a method for operating a data processing machine is described in which data about a state of the machine is written to a location in storage. The location is one that is accessible to software that may be written for the machine. The state data as written is encoded. This state data may be recovered from the storage according to a decoding process. Other embodiments are also described and claimed.

Accessing private data about the state of a data processing machine from storage that is publicly accessible
