摘要： 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.

摘要： 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.

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.
