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.

摘要翻译： 公开了在分层虚拟化架构中处理虚拟化事件的装置和方法的实施例。 在一个实施例中，装置包括事件逻辑和评估逻辑。 事件逻辑是识别虚拟化事件。 评估逻辑是为了响应于虚拟化事件来确定是否将控制从子客户端传送到父访客。

摘要： A system and method for allowing a virtual machine monitor to assume control of a system when the current privilege level of guest software meets a privilege level exiting criteria. The processor detects that the current privilege level meets the criteria and then transfers control from the guest software to the virtual machine monitor. The virtual machine monitor may decline to assume control for certain privilege level changes or values.

摘要： 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.
