Systems support for virtualization

近年来，已经看到了部署硬件虚拟化作为帮助管理现代计算机系统的规模和复杂性的技术的决定性努力。 虚拟化允许对单个物理计算机进行分区，并使其显示为隔离的虚拟计算机的集合，每个虚拟计算机运行独立的操作系统和应用程序堆栈。 AMD和英特尔已经发布了CPU扩展来帮助虚拟化，所有主要的操作系统供应商都宣布在其系统的下一个版本中支持虚拟化。

Recent years have seen a decided effort to deploy hardware virtualization as a technology to help manage the scale and complexity of modern computer systems. Virtualization allows a single physical computer to be partitioned and made to appear as a collection of isolated virtual computers, each running an independent operating system and application stack. AMD and Intel have released CPU extensions to aid virtualization, and all major OS vendors have announced virtualization support in the next releases of their systems.
