Features of virtual machines: 1. Multiple operating systems can be run on the same PC at the same time; 2. Another release version of the same operating system can be installed on the virtual machine without repartitioning the hard disk. ; 3. Share files, applications, network resources, etc. between virtual machines; 4. You can use all the resources of another virtual machine on the same computer.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

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. Everything that can be done on a physical computer can be done on a virtual machine. When creating a virtual machine on a computer, you need to use part of the hard disk and memory capacity of the physical machine as the hard disk and memory capacity of the virtual machine. Each virtual machine has an independent CMOS, hard disk and operating system, and the virtual machine can be operated like a physical machine.

The role of virtual machines

Through virtual machine software, you can simulate two or more virtual computers on a physical computer. These virtual machines are completely Works just like a real computer, such as you can install the operating system, install applications, access network resources, and more. To you, it's just an application running on your physical computer, but to an application running in a virtual machine, it's a real computer.

Therefore, when you conduct software evaluation in a virtual machine, the system may also crash; however, only the operating system on the virtual machine crashes, not the operating system on the physical computer. Moreover, using a virtual machine Using the machine's "Undo" function, you can immediately restore the virtual machine to the state it was in before the software was installed.

Features

1. Multiple operating systems can be run on the same PC at the same time. Each OS has its own independent virtual machine, just like on the network A standalone PC.

2. Install another release version of the same operating system on the VM without repartitioning the hard disk.

3. Share files, applications, network resources, etc. between virtual machines.

4. You can run applications in C/S mode, or you can use all the resources of another virtual machine on the same computer.
