    摘要: Embodiments of apparatuses, methods, and systems for injecting virtualization events 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 initiate a transfer of control of the apparatus from a host to a guest running on a virtual machine. The recognition logic is to recognize a request from the host to inject a virtualization event into the virtual machine. The evaluation logic is to identify an intervening monitor to handle the virtualization event.

    摘要: Embodiments of apparatuses, methods, and systems for virtualizing performance counters are disclosed. In one embodiment, an apparatus includes a counter, a counter enable storage location, counter enable logic, and virtual machine control logic. The counter enable storage location is to store a counter enable indicator. The counter enable logic is to enable the counter based on the counter enable indicator. The virtual machine control logic is to transfer control of the apparatus to a guest. The virtual machine control logic includes guest state load logic to cause a guest value from a virtual machine control structure to be loaded into the counter enable storage location in connection with a transfer of control of the apparatus to the guest.

    摘要: Embodiments of apparatuses and methods for processing virtual machine control structure shadowing are disclosed. In one embodiment, an apparatus includes instruction hardware, execution hardware, and control logic. The instruction hardware is to receive instructions. A first instruction is to transfer the processor from a root mode to a non-root mode. The non-root mode is for executing guest software in a virtual machine, where the processor is the return to root mode upon the detection of a virtual machine exit event. A second instruction is to access a data structure for controlling a virtual machine. The execution hardware is to execute the instructions. The control logic is to cause the processor to access a shadow data structure instead of the data structure, without returning to the root mode for the access to be performed, when the second instruction is executed in the non-root mode.
