Thread-topic: [Xen-devel] Help!!! mm.c:566: Non-privileged (5) attempt to map I/Ospace 00000000
> Recently, my Xen always generates complains like  "mm.c:566:

In what way does the system become unstable? Does the guest that caused
the error (domain 5 in this case) become unstable, or do you loose the
whole system? What OS are you running in the guest, and where did you
get the bits from and what version?

The message above is typically harmless and is seen during the boot of
some guests that attempt to map machine page zero.
