推荐答案

虚拟化是一个很大的话题，但粗略地说，虚拟化主要分为三个层次:

Virtualization is a big topic, but very roughly speaking there are three main levels of virtualization:

• 使用类型 1 hypervisor
的操作系统虚拟化
• 在现有硬件/操作系统上运行的虚拟机，例如虚拟机
• 高级虚拟机，例如JVM

我会推荐这本书:虚拟机，作者:JE Smith 和 R. Nair.

I would recommend this book: Virtual Machines, by J. E. Smith and R. Nair.

它几乎涵盖了所有虚拟执行环境:进程虚拟化、高级虚拟机、系统虚拟机、多处理器虚拟化等.

It covers pretty much all virtual execution environments: process virtualization, high level virtual machines, system virtual machines, multiprocessor virtualization, etc.

请注意，根据您感兴趣的级别，它与系统管理/硬件非常相关，因此您也可以在 serverfault 上提问.com.

Note that depending on the level which you are interested in, it gets pretty much related to system administration / hardware, so you might also ask the question on serverfault.com.
