Feynman (20. Februar 2010)

Richard Feynman war nicht nur einer der größten Physik des 20. Jahrhunderts sondern ist auch der Namensgeber für unseren neuen XEN Wunder-Server. Die Konfiguration erfolgt in wenigen Schritten:

Von SLES 11, SP1 booten

bei HP-Server broken_modules=ahci als Bootparameter angeben

Rescue booten

mkdir /c
mount /dev/sda2 /c
mount --bind /dev /c/dev
mount --bind /proc /c/proc
mount --bind /sys /c/sys

chroot /c /bin/bash

grub-install.unsupported --recheck /dev/sda

exit
