主要看哪种hipervisor了，type 1的话，基本上跟裸机区别不大，type 2可能会稍微慢
点。其实现在的I/O也主要就是存储设备和网络ACCESS了吧，大量运用VM的地方，通常
都是大data center，里面的存储都是基于网络的，起码是NAS，更牛的是SAN，而NIC更
是动辄就10G，甚至支持CNA，网络也不是瓶颈。

所以现在VIRTUALIZATION才可能这么火啊

: 如果不要求算得很快，没关系。
: 虚拟机主要问题是I/O跟不上。CPU还对付吧。
: 大型运算，不知道稳定性如何。

Finally write a second command doing the same thing into ...
