> > >       Xen: Use the ioreq-server API when available
> > >
> > >       The ioreq-server API added to Xen 4.5 offers better security than
> > >       the existing Xen/QEMU interface because the shared pages that are
> > >       used to pass emulation request/results back and forth are removed
> > >       from the guest's memory space before any requests are serviced.
> > >       This prevents the guest from mapping these pages (they are in a
> > >       well known location) and attempting to attack QEMU by synthesizing
> > >       its own request structures. Hence, this patch modifies configure
> > >       to detect whether the API is available, and adds the necessary
> > >       code to use the API if it is.
