Jeremy: Is an off the shelf, upstream pv-ops kernel capable of
being saved/restored/migrated? Somehow I can't seem to find the
suspend event channel setup code...

Keir: In the 2.6.18 kernel, the suspend event channel gets set up
even for Dom0. This as well as the registering of the shutdown
watch seems pointless (and dangerous in case something
connected to it say due to a bug) to me in that context. Am I
missing something?

Thanks, Jan
