虚拟机硬件特征有哪些(虚拟机可以虚拟硬件信息吗)

Advantages of virtual machines: It runs on the host and is completely independent. All operations in the virtual machine will not affect the host. Even if the virtual machine crashes, it is generally used for testing or experiments. Of course, it has Use these advantages as you wish.
Disadvantages: It is built on the host. After all, it is a virtual machine and a file, which can be easily damaged.
Virtual machine (Virtual Machine) refers to a complete computer system with complete hardware system functions simulated by software and running in a completely isolated environment.
The virtual system generates a new virtual image of the existing operating system. It has exactly the same functions as the real windows system. After entering the virtual system, all operations are performed in this new independent virtual system and can be installed independently. Run software, save data, have your own independent desktop without any impact on the real system, and have an operating system that can flexibly switch between the existing system and the virtual image. The difference between a virtual system and a traditional virtual machine (ParallelsDesktop, Vmware, VirtualBox, Virtualpc) is that the virtual system will not reduce the performance of the computer. Starting the virtual system does not need to be as time-consuming as starting the windows system, and running programs is more convenient and faster; the virtual system only It can simulate the same environment as the existing operating system, while the virtual machine can simulate other types of operating systems; and the virtual machine needs to simulate the underlying hardware instructions, so the application running speed is much slower than the virtual system.

Homogeneity: The running environment of the virtual machine and the running environment of the physical machine are essentially the same, but there are some differences in performance.
Efficient: The performance of software running in a virtual machine must be close to that of software running directly on a physical machine. In order to achieve this, when the software is running in a virtual machine, most instructions need to be executed directly on the hardware, and only a few instructions need to be processed or simulated by the VMM.
Controlled resources: VMM needs to have full control and management authority over system resources, including resource allocation, monitoring and recycling.
