What is system Virtualization?
What is system virtualization? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.
The linux virtual machine belongs to system virtualization. System virtualization technology can virtualize multiple linux virtual machines on a physical computer system. They run in an isolated environment and can be used in different instruction set architectures.
System virtualization
System virtualization refers to the virtual creation of one or more virtual computer systems on a physical computer system. Virtual computer system (virtual machine for short) refers to a logical computer system with complete hardware functions, including operating systems and applications, that runs in an isolated environment using virtualization technology. Many different operating systems can be installed in a virtual machine, and these operating systems are independent of each other. Virtual machines and physical computer systems can have different instruction set architectures. This makes each instruction on the virtual machine have to be simulated on the physical computer. Obviously, it can lead to poor performance. Therefore, we generally make the instruction set architecture of the virtual machine the same as the physical computer system. In this way, most of the instructions will run directly on the processor, and only those instructions that need to be virtualized will run on the virtual machine.
In addition, there are 1, storage virtualization 2, memory virtualization 3, network virtualization and other technologies.
The answer to the question about system virtualization is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
