I've grabbed an image of a 2003 server that had 4 CPUs. Once I get it into a VM I can reduce it down to 2 CPUs with no problem. But then going back and reducing from 2 CPU to 1 CPU, causes the CPU to spike to 100% and I can't get in the box to fix the HAL. I've also tried changing the HAL from multiprocessor to uniprocessor prior to going from 2 CPU to 1 CPU.
Any thoughts on how to fix this? I don't usually have this problem when taking images from boxes that have 2 CPUs to start with. Not sure why the 4 CPU thing is causing such a problem.
