Method, apparatus and system for bi-directional communication between a virtual machine monitor and an ACPI-compliant guest operating system

摘要

A method, apparatus and system enable bi-directional communications between a virtual machine monitor ("VMM") and an Advanced Configuration & Power Interface ("ACPI") compliant guest operating system. In one embodiment, a virtual machine ("VM") may be designated as the owner of the host platform ("Policy VM"). The Policy VM may communicate with the VMM to control all configuration and power management decisions on the platform.
