But the boot process was extremly slow, actually the desktop screen never showed up then the VM just reboot automatically. So is there anything I can do to solve this problem or the truth is Win7 by design just cannot handle that mount of CPUs even with Win7 Ultimate?

This question would probably be better suited for a microsoft specific forum. 
But I think if you want to pass that many CPUs to windows, you need to use a 
version of windows server, not plain windows 7
