The traditional physical machine needs to be shut down to carry the whole machine during migration, but how to move the virtual machine during migration?

Traditional physical machines need to stop and carry the whole machine during migration, while virtual machines only need to migrate their own stored files during migration. According to the relevant information, a virtual machine refers to a complete computer system that is simulated by software and runs in a completely isolated environment, and only needs to migrate its storage files. What can be done on a physical computer can also be achieved on a virtual machine. When creating a virtual machine in a computer, it is necessary to take out a part of the hard disk and memory capacity of the physical machine as the hard disk and memory capacity of the virtual machine.
