virtual machine (Virtual Machine) It is a complete computer system simulated by software . The work that can be done in the physical computer can be realized in the virtual machine . When creating a virtual machine in a computer , Part of the hard disk and memory capacity of the physical machine should be taken as the hard disk and memory capacity of the virtual machine . Each virtual machine has its own CMOS、 Hard disk and operating system , The virtual machine can be operated as if it were a physical machine .
If in Program freezing occurs in the virtual machine , It will not affect the program operation and the normal operation of the operating system running outside the virtual machine .
Hardware requirements for using virtual machines :
After all, virtual machines concentrate the tasks of more than two computers on one computer , Therefore, the requirements for hardware are relatively high , Mainly CPU、 Hard disk and memory .
The role of virtual machine
1. You can install a variety of demo environments , Easy to do all kinds of tests ;
2. Reduce unnecessary garbage installation procedures 、 Infrequently used programs 、 Or the test program runs on the virtual machine , Ensure the rapid operation of the host ;
3. Avoid every re installation , For some infrequently used , And it requires better tools for confidentiality , It can run in a single environment ;
4. Some programs and tools for testing can be installed and completely deleted in the virtual machine ;
5. Experience different versions of the operating system , Such as Linux、Mac etc. .
