虚拟化是一个广义的术语，在计算机方面通常是指计算元件在虚拟的基础上而不是真实的基础上运行。虚拟化技术可以扩大硬件的容量，简化软件的重新配置过程。CPU的虚拟化技术可以单CPU模拟多CPU并行，允许一个平台同时运行多个操作系统，并且应用程序都可以在相互独立的空间内运行而互不影响，从而显著提高计算机的工作效率。-Virtualization is a broad term, in the computer usually refers to components in the calculation based on virtual rather than real based on the run. Virtualization technology can expand the capacity of the hardware to simplify the software re-configuration process. CPU virtualization technology can single-CPU simulation of multi-CPU parallel, allowing a platform to run multiple operating systems and applications can be independent of each other space to operate互不影响, thereby significantly improve the efficiency of the computer.
