Such VM acts like 4-way or 8-way machine. Nine times out of ten, a single cpu guest is going to be a better option than a smp/multie core guest. I've seen idle windows guests go from using nearly 200% cpu for -smp 2 to ~5-10% for -smp 1. Unless your guest is actually using all that cpu all the time, you're going to be wasting a decent amount of cycles. > > Is there any way howto expose CPUs differently for this kind of problem?
