Don't you need to propagate the interrupt here? In Xen, we inject the
interrupt using the IDT. As a module, you don't have access to that.
However, you could use a software interrupt to reraise it.
I got your code running this afternoon (it's quite cool) but I noticed a
ton of "rtc: lost some interrupts at 1024Hz." messages which leads me to
believe.. you're dropping interrupts :-) Things seem to hang trying to
bring up eth0 in the guest.
BTW, have you setup a mailing list yet?

Anthony Liguori
