I use Qemu for several tasks, but its primary use is for testing programs. It has a wonderful feature called "snapshots", where you can save a known state of the Virtual Machine you can fall back to if anything goes wrong.
For my recent adventure with keyboard layouts I researched several sources on Qemu and noticed [...]

Here are some screenshots:

Last October I wrote some posts about installing older Slackware versions on VMware. I have since sort of abandoned VMware for several reasons:

It might be free for personal use, but it is not Open software

The latest versions need PAM, which can be installed on [...]
