The so-called "virtual" in the operating system refers to turning a physical entity into several logical counterparts through some technology. The physical entity (the former) is real, that is, it actually exists; The latter is virtual, which is what users feel. Therefore, the technology used to realize virtualization becomes virtual technology. A variety of virtual technologies are used in the operating system to realize virtual processors, virtual memories, virtual peripherals and virtual channels.

Now the network world is developing towards virtualization. In the next two years, it is estimated that 60% of computer desktops will be virtualized, that is, more and more people will use virtual operating systems.
