This is unlikely to be a problem in qemu-dm; qemu-dm gets told the
guest-physical of IO requests addresses by Xen.  I would suggest that
the starting point would be xen/arch/x86/hvm/io.c and its subroutines
and callers.  That's the place where the IO requests are collected and
sent on to the device model (ie, qemu-dm).
