虚拟机有哪几种类型(虚拟机的三种模式及用途)

The virtual machines include Microsoft virtual machine, Mac virtual machine, BM virtual machine, HP virtual machine, SWsoft virtual machine, SUN virtual machine, Intel virtual machine, AMD virtual machine, Java virtual machine, BB Virtual machines, Linux virtual machines, several commonly used virtual machines are introduced below.

1. Vmware

Using Vmware, you can run various Linux distributions, Dos, various versions of Windows, Unix, etc. at the same time. You can even install multiple programs on the same computer. Linux distributions, multiple Windows versions.

2. ParallelsDesktop

ParallelsDesktop is a virtual machine solution suitable for the MacOS platform. You can access many applications on both Windows and Mac systems on the same Mac computer at any time without restarting.

3. VirtualPC

VirtualPC allows you to run multiple PC operating systems on a workstation at the same time. When you switch to a new OS, it can provide you with a safe way to run traditional applications. environment to maintain compatibility, it saves reconfiguration time so your support, development, and training efforts can be more efficient.

Extended information:

The virtual system generates a new virtual image of the existing operating system , it has exactly the same functions as a real Windows system. After entering the virtual system, all operations are performed in this new independent virtual system. You can install and run software independently, save data, and have your own independent desktop. It will not affect the real Windows system. A type of operating system that has any impact on the system and has the ability to flexibly switch between existing systems and virtual images.

The difference between a virtual system and a traditional virtual machine 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 can only simulate The same environment as the existing operating system, and 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.

Virtual machines include: Linux virtual machine, Java virtual machine, Microsoft virtual machine, Mac virtual machine, BM virtual machine, HP virtual machine, SWsoft virtual machine, etc. 11 types.

1. Linux virtual machine

A virtual Linux operating environment installed on Windows is called a Linux virtual machine. It is actually just a file, a virtual Linux environment, not a real operating system. But their actual effect is the same. So it is best to install it on a virtual machine.

2. Java Virtual Machine

Java Virtual Machine (JVM) is the abbreviation of JavaVirtualMachine. It is a fictitious computer that simulates various computers by simulating it on an actual computer. Functional simulation is implemented. The Java virtual machine has its own complete hardware architecture, such as processor, stack, registers, etc., and also has a corresponding instruction system.

Extended information:

Virtual machine (VirtualMachine) refers to a complete hardware system function simulated through software A complete computer system 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.

Virtual machine technology is a type of virtualization technology. The so-called virtualization technology is to transform things from one form to another. The most commonly used virtualization technology is the virtualization of memory in the operating system. , the memory space required by the user during actual operation may be much larger than the memory size of the physical machine. Using memory virtualization technology, the user can virtualize a part of the hard disk into memory, and this is transparent to the user. For another example, virtual private network technology (VPN) can be used to virtualize a safe and stable "tunnel" in a public network, making users feel as if they are using a private network.
