Hypervisor(1)

之前有说过Android手机虚拟化，使得一个平台上增加hypervisor后有多个os,现在结合一篇，熟悉hypervisor的benefits:

Benefits

Consolidation: Systems that require multiple processors are expensive and inefficient in terms of hardware costs and power consumption.-->这个对嵌入式系统很有益处，毕竟成本很重要。

Innovation and differentiation: It can be difficult to create highly differentiated devices when development is constrained to one operating system. -->android手机平台如果能继承所以优秀的裁剪过的os的features,你觉得如何？ 比如，一台手机，同时跑了linux/symbian/wm,无敌了吧～

Efficient adoption of multicore: Multicore processors promise increased performance and reduced power consumption; however, adapting software developed for single processors to run on multicore processors can be a daunting task.-->信多核，得永生。
