Because qemu itself only supports 16 virtual interrupt lines by far, with 
identity mapping between pic pin and ioapic pin.

Dear all,
     Recently, I find a problem which you can only see 16 interrupts in
Gos(winxp), and as we all known, there is 24 interrupts in a apic. Why? I
have puzzled for long time about this issue. Somebody can help me?  Thanks
lot.
