Qemu, snapshots, temporary files, where they go and how to change that
March 14th, 2011 by Niels Horn in Qemu, Slackware, Virtualization
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 [...]
QEMU and Brazilian keyboards
March 11th, 2011 by Niels Horn in Qemu, Slackware
This post explains how to get QEMU working on a host with a pt_BR (ABNT2) keyboard fro Brazil. These keyboards have the "dead" accent-keys and a few modifications that are specific to this layout.
The Problem
For a long time there have been some problems with Brazilian keyboards and QEMU.
In theory, using the standard QEMU, without a [...]
Packages for ARMedslack
September 5th, 2010 by Niels Horn in ARMedslack, FBReader, QComicBook, Qemu, RRDtool | No Comments »
No, I did not abandon ARMedslack, the official port of Slackware to the ARM architecture… It was simply a matter of lack of time (or a question of priorities, depending of your point of view).
But this weekend I finally found some time to setup a clean build environment based on the stable ARMedslack 13.1 version.

Benchmarking with nbench
February 15th, 2010 by Niels Horn in ARMedslack, Hercules, Qemu, Slack/390, emulation, nbench
Since I was doing some tests with Slackware running on different platforms (Slack/390, Slack/390x, ArmedSlack on Qemu, etc.) I wanted to compare the performance of the different setups.
I used a (quite old) utility called nbench that was originally written in 1995 but still is a simple way to compare how processors perform, emulated or real. [...]
Emulating a mainframe on ArmedSlack
February 15th, 2010 by Niels Horn in ARMedslack, Hercules, Qemu
In preparation for a future project, I built Hercules on ArmedSlack, running in Qemu. The idea was to test the concept of running the mainframe emulator on the Arm processor.
The result was quite usable, at least for the older mainframe operating systems like MVS.
Here are some screenshots:
Starting Hercules on ArmedSlack:
The 3270 terminal connecting to the [...]
Older Slackware versions (VI)
June 13th, 2009 by Niels Horn in Qemu, Slackware, VMware
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
It is a hassle to keep it functioning with every kernel change
The latest versions need PAM, which can be installed on [...]
