Qemu: A lightweight Virtual Machine Manager

Virtual machine applications such as VMware or VitualBox is very popular, but is there a similar application a more “lightweight” and is opensource? One alternative that I recommend is Qemu, originally only runs on UNIX-family operating system platforms (including Linux).

At present, Qemu has been created which version can be run on the Windows operating system platform. In this article I will exemplify a few steps how to install the operating system using Mikrotik (one Linux distro) to networked learning.
