As per a subsequent email, 'send_guest_global_virq(dom0, VIRQ_DOM_EXC)'
never reaches Dom0 (unless xenstored is restarted, then a whole lot of
other stuff doesn't work but the send_guest_global_virq actually does
work).

Debugging in xenstored shows that port 18 was returned from the kernel.

Debugging in xen shows that port 18 is definitely what the hypervisor
allocated.

I added some debugging to the send_guest_global_virq code path too, but
as soon as the DomU I created for testing shut down, my Dom0 became
unresponsive so I suspect I have botched my debug statements. It's
nearly 12:30am here and the server is at work so I'm done for the day.

The most frustrating thing is that I just know it's going to be some
stupid little configuration thing on my server causing all of this!!!
