   I think we need to be careful not to hide too many assumptions about
the guest in Xen as well.  We can't be certain another OS won't use
region 7 like this at some point.  I agree that a requiring a user to
know certain memory layout attributes is way too low level, but what
about a simple flag like "guest = windows".  Yes, it's not automatic
like the code is now, but it feels more supportable.  Thanks,
