MacOSX guest cannot boot SMP without -kvm-irqchip 

Problem :
On MacOSX SMP guest, got Error message and lock on boot( with -v option)
There is no problem with single core and could boot without -kvm-irqchip.


Failed to start CPU 01, rebooting...
CPU halted.
Screenshot attached.

The command I use to launch the vm is:
qemu-kvm -hda ./MacOSX.vdi -net nic,vlan=0,model=rtl8139 -net user,vlan=0,hostname=emu -boot c -smp 4

The problem appearing with -no-kvm-pit.
The problem stops appearing with -no-kvm-irqchip.
The problem stops appearing with -no-kvm switch. (offcourse)
