单机游戏虚拟机有和没有啥区别(单机版网游为什么要用虚拟机)

Dianlong Babu virtual machine and Duokai both refer to a technology used to run multiple game clients at the same time, but they have some differences.
1. Tianlong Babu Virtual Machine: This is a method to create a completely independent operating system environment through virtual machine software to run multiple game clients. Virtual machine software can simulate multiple virtual computers, each of which has its own operating system, hardware resources, etc. Using virtual machines can achieve complete isolation. Each game client runs in a different virtual machine without interfering with each other, and each virtual machine can also set up hardware resource allocation independently.
2. Multi-open: Multi-open refers to starting multiple game clients at the same time in the same operating system environment. This can be achieved through some special software or by modifying the game client. Multi-open mainly realizes running multiple clients at the same time by controlling the allocation of processes, threads and resources. However, under the same operating system environment, there may still be some interference between different game clients.
In summary, the Tianlong Babu virtual machine achieves a completely isolated multi-open effect through virtualization technology, while multi-open is to run multiple game clients in the same operating system environment, and there are certain problems. Interference possible. Which method you choose to use depends on your needs and actual situation.

Virtual machines usually only use VMware, Microsoft Virtual PC and other tools. You can use them to simulate PCs. You can install Windows XP in the virtual machine to study various viruses without worrying about infecting the real system. It is also commonly used Learn Linux. The hard disk of the virtual machine is one or several files on your real system. It is very convenient to backup, restore and transfer.
Emulators usually refer to programs that simulate previous game consoles. They can be used to play many classic games from the past, such as Famicom emulators, PS emulators, and GBA emulators, so that we can play some on the computer. A classic game. For example, Street Fighter, Super Mario, King of Fighters, Metal Slug, Pokemon, etc.
In essence, there is no difference between a virtual machine and an emulator. They all use the PC’s CPU memory and hard disk space to simulate a The new environment is just a different environment they simulate. In actual use, because the emulator is only used for playing games, and the virtual machine can easily allow you to experience many other systems in Windows XP, many people think that the virtual machine is more powerful than the emulator. As everyone knows, simulating a PS2/PSP environment is thousands of times more difficult than simulating an XP environment. Because it is necessary to simulate environments with different architectures, the efficiency of virtualization is extremely low, and current computers still cannot meet the performance requirements.

The difference between a virtual machine and a real machine is: different properties, different running performance, and different types of operating systems.

1. Different natures

1. Virtual machine: A virtual machine is a virtual computer system image simulated by software with complete hardware system functions and running in a completely isolated environment.

2. Real machine: A real machine is a complete computer system with complete hardware system functions and running in a completely isolated environment.

2. Different running performance

1. Virtual machine: Virtual machine will not reduce the performance of the computer. Starting the virtual machine does not need to be as time-consuming as starting the real machine system, and running the program is more efficient. Convenient.

2. Real machine: The more programs running on a real machine, the easier it is to reduce the performance of the computer, the more time-consuming it is, and the slower it will be to run other programs.

3. Different types of operating systems

1. Virtual machine: A virtual machine can simulate other types of operating systems.

2. Real machine: The real machine only has a fixed operating system, and other types of operating systems require reinstalling the system.
