Scott tsai's answer whether i must use arm11mpcore cpu,i just can emulator 4 
Can i change the number and get the number i want?
And Versatilepb.c i use the same way like Realview.c.
Qemu shell can find 2 cpus,but the OS can't install.
I am fail.

Now i have another question.
1.Arm's multi-core emulator whether can use arm Versatile? 
If it can, i must do what?

2.If can not use arm Versatile,can talk me which can be emulator multi-core 
except arm RealView.

Sorry.I don't know how to do use qemu emulator RealView
and where to download theRealView's kernel and initrd file? 
Anyone have some step to emulator arm Realview.
