I can't find any documentation that explain how to add multiple IOAPIC to QEMU. Is it possible to do this? Thanks!!

QEMU can only report one IOAPIC in its ACPI tables, so you probably can't have more than one. (And if you can have more than one, it won't be listed in the MADT, so you won't be able to use it.)
