虚拟机上安装Linux操作系统（vm装linux系统）

Virtual machines (VM) are becoming increasingly popular for people who need reliability and secure performance from their systems. One of the best ways to use such a machine is to install a Linux operating system. Linux is an open source operating system popular in various areas. It is very easy to set up and install a Linux operating system on a VM.

First of all, one has to start with selecting the right Linux distro to install. There are several choices and users need to consider all the features they require. Popular, reliable and stable distributions include Ubuntu, CentOS, Linux Mint, and Debian. Debian, in particular, is the base of most Linux distributions and is a good choice for new users. After selecting the right distro, one can download the ISO file, or the installation image.

The second step is to create a virtual machine for installation. This can be done using popular tools like VirtualBox, VMware Fusion, or KVM. Each of these tools has its own advantages and users need to carefully research which one is the best for them. After creating the virtual machine, users can now insert the ISO file in it and begin the installation process.

This usually involves booting from the virtual disk, selecting a language, setting up a default account and setting the system clock. Once all of these steps are completed, users can start setting up the system. They can install most Linux applications and even open source programs like LibreOffice or Gimp.

Finally, once all the applications and services are set up, users can take a snapshot and save it. This step ensures that they can go back to their initial installation state in case something goes wrong.

In conclusion, installation of Linux on a virtual machine is not a difficult task. Users just need to download the right distro, create a virtual machine, insert the ISO file and configure the settings. Furthermore, they should also take snapshots of their installation in case of emergency situations. With these steps, users are ready to start exploring and taking full advantage of the Linux environment.
