Maybe you need to allocate more CPU ressources to dom0; this is done with
the "xm sched-sedf" command (note that displaying the actual parameters doesn't
work). I've not found much documentation on this, so I can't tell you exactly
what to type. You'll probably have to try a few things ...

What is the last line printed ? I'd recommend also trying a serial console,
to see if the hypervisor has something to say when the kernel tries to
reboot. I've got one report of the hypervisor having troubles to reboot
but it seems to be an issue in the hypervisor itself ...
