Good 2008 to everyone

desert in egypt, by Jochem

There is only one week between this picture and the one below.... The trick is of course the invention of the aeroplane, which enabled me to make a trip to Egypt, a wonderful country. See more soon in my photo section of this site.

Anyway, good 2008 to everyone!

Qemu/kvm and xorg screen resolution

Fast virtualization is cheap nowadays on linux. Just apt-get install kvm on a recent kernel and VT-enabled processor and you are ready to run all kind of different os-es on your host. No more recompiling the vmware kernel modules *again* or fiddling with xen-modified kernels and difficult networking setups. Yeah!

One problem I encountered was getting a decent resolution (f.g. 1280x1024 or higher) in the guest xserver (xorg). Google was not really helpful this time so therefore I post this note for future reference. Qemu emulates two kind of video cards, standard is a cirrus, -std-vga provides you with a vesa one. Vesa was not able to help me (garbled screen), so using the (default) cirrus emulator is the way to go for a linux guest.

The trick was in changing the monitor sync and refresh rates, autodetection did not work properly (in my centos 4.0 guest). So here is my working snippet of /etc/X11/xorg.conf: 

Section "Device"
  Identifier  "Generic Video Card"
  Driver      "cirrus"
EndSection

Section "Monitor"
  Identifier  "Generic Monitor"
  Option    "DPMS"
  HorizSync 28-64
  VertRefresh 43-60
EndSection

10 years GNU/Linux

I am using GNU/Linux for 10 years! As a celebration I made a white chocolate cake (recept) with tux on it. Thanks to all the volunteers for this great combination of free software. In the past I have used all major distributions, nowadays I am stuck with Debian. In fact I am rather distro-agnostic, if it runs xterm, screen, vim, mplayer, gcc and mutt I am happy. Pro is the nice Debian philosophy, con the fact that is has not incorporated SElinux yet. So perhaps I will switch in the next 10 years again?

Sidenote for R. Stallman: when i am using gnu/linux 25 years I promise to make a gnu cake :-D.

Older again

Last saturday I lost/gained another year depending on your worldview. Anyway, had a good day between the apes.
