libvirt users - Oct 2014 - Will over-allocation of vCPUs be counterproductive to VM Win7 Ultimate?

Hi all,
Will over-allocation of vCPUs be counterproductive to VM Win7 Ultimate? I
allocated 32 (out of 64 physical cores in 8 NUMA cells, and 128G out of 2T
physical RAM) to the VM. 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?
