Virtual machine (VM) or virtualization software helps in running many operating systems within an operating system on a computer. These software are freely available for all major desktop platforms such as Microsoft Windows, macOS and Linux. There is no special requirement to run virtualization software, but if you have a good configuration computer, you can run many guest operating systems without slowing your actual system.
For example, installing Linux or several Windows on a PC requires some things, including bootable USB or disk and separate fixed space, but using the virtual machine software, you can immediately run any guest OS by using an ISO image file.
These are the best virtual machine or virtualization software for desktops and laptop computers:
