   Right, XEN_PRIVILEGED_GUEST is always on right now because there's no
prompt to change it.  To fix that, do this:

        default y
          Used in drivers/xen/privcmd.c.  Should go away?

Then you can make some decisions based on it like the previous chunk
showed.  I would assume you'd then make is set in the defconfig for
dom0, but not in domU.  Hope that helps,
