This is generally being caused by tools like hwinfo that try to map
BIOS space
(which is meaningless in DomU-s; only Dom0 is allowed to see the real
BIOS
space). Having looked at it quite a while back I thinks there's
nothing
reasonable we can do at the Xen or kernel side, it's the offending tool
that
needs fixing if this message is considered a problem.
