On grub.cfg now I have: ... multiboot /boot/xen.gz placeholder dom0_mem=4G,max:4G loglvl=all guest_loglvl=all ... But I'm unable to see debug related information in log files. This was the test of Anthony Perard with all details about the problem: http://lists.xen.org/archives/html/xen-devel/2013-05/msg02050.html So my questions are: - Is your patch aimed to completely solve cpus instrictions with MMIO operands > 8 byte or - does it need also some qemu changes? I also added qemu-devel and anthony perard on cc.
