The xendomains script has not proved to be very reliable. I've seen a number
of bugzillas with a similar complaint to you, that only a (random) fraction 
of guests successfully start upon boot. My best guess is that the high load
causing by starting lots of guests at boot causing timeouts when setting
up backend devices & thus crashes the guest. Not had any time to investigate
it seriously, or even see if this guess is correct.
