It uses static DSDT table like the way x86 uses. Currently the DSDT table only contains processor device objects and it generates the maximal objects which so far is 128. While the GUEST_MAX_VCPUS is defined under __XEN__ or __XEN_TOOLS__, it needs to add -D__XEN_TOOLS__ to compile mk_dsdt.c. Also only check iasl for aarch64 in configure since ACPI on ARM32 is not supported.
