Consolidation of the basic knowledge system of virtualization

Comb out the basic knowledge frame of the virtualization, enrich the framework gradually, and summarize the deep learning of the node.

Simulator Principle

Understanding the principles of the emulator helps to understand the underlying principles of virtualization, so you need to supplement the basics appropriately.

As I understand virtualization, VMM intercepts instruction operations, fetch operations, IO operations in VMS, simulating results and feedback. The VM itself is not exposed to physical hardware, or can be contacted but strictly limited by VMM management.

Here is my blog address, more basic knowledge of virtualization articles, you can see the communication in my blog.
