本文介绍了虚拟化的概念，包括硬件虚拟化，快照、迁移和故障转移等关键技术。硬件虚拟化创建了能够像真实操作系统一样的虚拟机。快照是一种增量备份，用于保存和恢复虚拟机的状态。迁移则允许虚拟机在不同主机间移动，而故障转移确保在主机故障时虚拟机能从备份状态恢复。
什么是虚拟化（virtualization）
首先是wiki上面对于虚拟化的定义
In computing, virtualization refers to the act of creating a virtual (rather than actual) version of something, including virtual computer hardware platforms, storage devices, and computer network resources.
Virtualization began in the 1960s, as a method of logically dividing the system resources provided by mainframe computers between different applications. Since then, the meaning of the term has broadened.

如今的虚拟化，wiki百科上面被分为几个种类，主要有以下三种：
- 硬件虚拟化（Hardware Virtualization）
- Desktop virtualization
- Nested virtualization
