为什么电脑装虚拟机很卡(电脑装虚拟机需要什么配置)

This configuration
If
open two virtual machines, the system will freeze.
If you open a W7 virtual machine, it will freeze.
The physical memory is too little.
It is recommended to use 4G memory

1. After using the virtual machine, you are usually used to suspending it, because shutting down takes time and suspending is relatively fast. As everyone knows, this will generate a temporary file in the operating system directory of the virtual machine to save the current system status, with the extension: vmem.

2. After using the virtual machine, choose to close the client instead of suspending the client. In this way, there will be no lag. My computer configuration is Intel I7 CPU and 16G memory. If I choose to suspend the client, it will also be laggy.

3. The method is actually very simple, but most people find it troublesome to shut down the client and will choose to suspend the client. Problems causing virtual machine latency are often mistaken for hardware issues.

(1) Systems above win7 have better support for hardware with stronger performance than xp systems, but this determines whether your computer is stuck. The main factor of the card is the hardware performance, not the win7 system. Your current configuration is too weak to play with a virtual machine, or you can use it lightly. The so-called heavy use means running some large programs or multiple games in the virtual machine. In that case, your current laptop will definitely be unable to bear it.
(2) The virtual machine’s demand for hardware performance
① The virtual machine first has a strong demand for CPU performance
The realization of most of the hardware performance of the virtual machine relies on the CPU Simulation, so a powerful physical machine CPU is an essential weapon for playing with virtual machines. Multi-core CPUs are better, and powerful single-core performance is the icing on the cake;
② The memory capacity of virtual machines Huge demand
As the name suggests, it is equivalent to a virtual computer. It requires more than 1G of memory to smoothly run the Windows system in the virtual machine. If you run large software in the virtual machine system, the memory requirements Larger, and your physical memory is only 1G, it is obviously not suitable for running a virtual machine;
③Virtual machines have high specifications for hardware read and write speed
In order to maintain themselves, the physical machine system operation, and running the virtual machine software, while constantly reading and writing to the hard disk, and the virtual machine is also equivalent to an independent computer, reading and writing to the virtual hardware (the virtual hard disk is a large file on the physical hard disk), Under the double pressure of reading and writing, the notebook's low-speed mechanical hard drive cannot withstand it and will inevitably freeze abnormally, both in the physical machine and in the virtual machine.
(3) The solution
① It is nothing more than upgrading the hardware and buying a notebook equipped with a higher-end CPU. The high-end CPU for home notebooks is nothing more than i7, with four cores and eight threads. The desktop version of i7 The frequency will be reduced to around 2 o'clock.
②The second is large-capacity memory. Mid-to-high-end notebooks are generally equipped with 8G memory capacity and expanded memory slots. If you want to play virtual machines freely, it is best to expand the memory to 16G. Of course, it depends on your specific situation. Depends on the usage environment.
③ Finally, there is the hard drive. Due to size limitations, notebooks cannot be equipped with normal or high-speed mechanical hard drives to solve the hard drive bottleneck problem. Currently, the only solution is to add a "solid-state drive".
The answer is not easy, I hope it can help you. If you are satisfied, please help to adopt it, thank you!

Since the virtual machine simulates a new system on the original system, your computer uses double the memory when running the virtual machine. If your computer isn't powerful enough, lags are normal. It may be better if you install VMware
Tools.
