This is your problem, which has nothing to do with Xen AFAICT.

Firstly you probably want to start udev via the initscripts not by hand,
secondly you probably need other (distro dependent) initscripts to run
first to ensure things like /run/ are mounted.

I guess you are booting with init=/bin/sh or something similar?
