I have no idea > about start udev via initscripts. This is nothing to do with Xen, it's just normal (and expected) Linux knowledge I'm afraid. The /root/init.sh which I use is: #!/bin/sh set -x mount -o remount,rw / mount -t proc none /proc mount -t sysfs none /sys mount -t tmpfs none /run mkdir /run/lock /etc/init.d/udev start mount -t devpts none /dev/pts hostname -F /etc/hostname /etc/init.d/xencommons start echo 9 > /proc/sysrq-trigger cd /root exec /bin/bash But TBH if you don't know what an initscript is then it might be best if you try and find someone locally (e.g. in your department) who knows about Linux and ask them to help bring you up to speed.
