QEMU v4.0.0 released

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 Like often, Debian's wiki is obsolete, and even their QEMU images are 5 years old.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.

QEMU Gentoo : https://wiki.gentoo.org/wiki/QEMU/Options

QEMU official : https://qemu.weilnetz.de/doc/qemu-doc.html

KVM Performance : http://www.linux-kvm.org/page/Tuning_KVM

Anybody here using QEMU? What is your use case?

Mainly playing with old operating systems, I'm a retrocomputing enthusiast.

While years ago I would mainly use Virtual PC (I do miss its great GUI) and VMWare (and rarely bochs), qemu improved a lot and has (somewhat decent) support for so many more architectures. You can run Solaris for SPARC and Mac Os 9, for example.

We build our own Linux images (using Yocto) for various embedded devices and run the same images on QEMU for testing purposes.

Welcome to the Open Source experience... sadly.

I'm using it extensively, but as a build tool: https://github.com/multiarch/qemu-user-static
