This guide will teach you how to create and manage a VM in KVM using virt-install, virsh, and virt-viewer, which all make use of libvirt. For a beginner's guide and introduction to libvirt and virtualisation concepts, and why you would even want to use libvirt instead of, say, Virtualbox, see: https://jamesnorth.net/post/qemu-guide

Here's the scenario: your laptop is approaching 13 years of age, the internal NIC has suddenly stopped working, but you don't want to give up here. You uninstall Arch Linux and install Windows 10 just to check that the NIC is actually not functioning anymore—which it isn't. You buy a USB Wi-Fi NIC Adapter, carelessly not checking if the vendor's drivers have been mainlined into the Linux kernel. You boot into an Arch Linux live session and you don't have an internet connection. Here's what you do next.

In this exciting installment of "Adventures in X11", we'll perform precise operations on our clipboard to generate desired output. So, pick up your instrument, and let's get to work!

It involved a fair amount of research to figure out how to setup and use virt-manager, virt-viewer, and even understanding what QEMU/KVM/libvirt are and what they do. This is as much a reference for me as I hope it to be helpful for others looking to use these technologies.
