在虚拟化的学习过程中,对于特权资源,必须知道三个 context: virtual context, shadow context and physical context。同时需要具有如下两个mindsets:

  1. Know what is done by hardware, what is done by software
  2. Know what is done in root mode, what is done in non-root mode

详细的讲解可以参考Basic Concepts of Virtualization。若有疑问,可邮箱联系作者:ljm0910@mail.ustc.edu.cn
