CPU virtualization technology is very useful. For example, when running applications developed based on Win XP or Win7 in Win10 system, the program can run normally without incompatibility (some Except for compatibility issues with the program itself).

CPU virtualization technology is divided into two types: software virtualization and hardware virtualization. Software virtualization has low efficiency and consumes large resources; hardware virtualization can greatly improve efficiency and speed up the running speed of programs.
