My Windows PV drivers now know how to put a watch on something, so by
putting a watch on 'control' I can see the shutdown request from Dom0
(written to 'control/shutdown' I think). As I do nothing currently
though, a forced shutdown occurs very soon after.

If I understand the code correctly, as soon as I see the
control/shutdown node appear, I should read it, and then write a blank
string into it, which acknowledges the shutdown request and stops the
forced shutdown. I should then give windows the shutdown or reboot
command, depending on what I read from the xenstore node.

Sound good?

Thanks

James
