Actually, the problem is my assumption that xend would give me as long
as I wanted to shut down. I haven't yet put the code in to do the
shutdown, and I was concerned that the domain was still being
hard-shutdown anyway. You have enlightened me :)

As it turns out, there isn't really a way to do a shutdown from windows
kernel space. I need to write a usermode app/service to talk to the
driver, and initiate the shutdown from there.

Thanks
