Do you know what happens ? ... your report is very likely duplicating earlier ones where the ACPI root point cannot be found without it being properly propagated through by grub from EFI to Xen. Iirc the only way around that is to chainload xen.efi, if the grub used doesn't support the extensions needed to boot Xen via the multiboot2 protocol (support for which was added during the 4.9 development cycle).
