QEMU is a generic and open source machine emulator and virtualizer. QEMU works like VMWare, VirtualBox and etc.


You can download its installation file at https://www.qemu.org/download/

On Windows 10, you will see following diagram when you install QEMU.

You will surprisingly find nothing on the program group except a link to the documentation.

QEMU does not provide VM manager like VMWare, VirtualBox and etc - meaning it requires to run the necessary things like command line interface.
