Simon,

The full description of my problem, including all symptoms, is in my first
post in this thread.

It's always a single domU. I don't use xentop, but mpstat would show
a high "steal" value on one of the cpus if a domU was using 100%, wouldn't it?

That's not it: the guest is not using 100% CPU when frozen and I don't have
anything that would write excessively to the console - there are about 5-10
lines beyond the initial log from booting. Also, I don't get any previous
output from the buffer when I run "xm console".
