Last week, I intended to replace VirtualBox with QEMU for my personal use. The spartiate documentation made it really hard. I lack the competence to seriously contribute.
The official documentation just explains the numerous parameters. It also points to tutorials (wikibook, etc), which unfortunately are very basic and out of sync. Even Arch Linux does not provide a good documentation (lack of clarity, some obsolete syntax, "Networking" section is a mess...). Like often, Debian's wiki is obsolete, and even their QEMU images are 5 years old. I had to combine the following 3 sources and a lot of try and guesses to build my VMs.
