English to Chinese Tech/Engineering IT (Information Technology) virtualisation

The first step taken by both chipmakers was to equip their CPUs with the capability to intercept and redirect requests to alter the system’s state. In the one machine/one OS model, the operating system is trusted to alter, unchecked, the state of the CPU, chip set, and peripherals. That’s an obvious barrier to efficient virtualization; guest OS instances would crash if their system changes, however irresponsible, didn’t stick. Keeping up the charade of a one-owner system is the expensive part of virtualization.
这两家芯片生产商采取的第一步都是为各自的CPU配置了这一功能：截取及重定向改变系统状态的请求。在一台机器、一个操作系统的模式下，操作系统有权在未经检查的情况下改变CPU、芯片组及外围设备的状态。这对高效率的虚拟化而言显然是个障碍。XXX，客户操作系统实例就会崩溃。确保单机主系统是虚拟化机制当中开销很大的一部分。
