Je tente de faire marcher UML sous debian mais je me heurte à un problème.
Voici ce que j'ai fais :
2. Installation
sudo aptitude install user-mode-linux cdebootstrap
1. Creation du rootfs
dd if=/dev/zero of=etch.img bs=1k seek=4M count=0
/sbin/mkfs.ext3 -F etch.img
mkdir /tmp/rootfs
sudo mount -oloop etch.img /tmp/rootfs/
sudo cdebootstrap etch /tmp/rootfs/ http://ftp.de.debian.org/debian
sudo cp -a /usr/lib/uml/modules/ /tmp/rootfs/lib/
sudo umount /tmp/rootfs |
Je tente alors de demarrer mon UML :
gandalf@stormrage:/data/vm/uml$ linux ubd0=etch.img |
Et j'obtient cette erreur :
