The rules for CPU count in XP-Pro are as follows: the physically chip that you install on your motherboard is referred to by M$ as a CPU. XP-Pro will only allow up to two CPUs. Each physical CPU may have as many processors on it as will fit. M$ calls these processors "cores". XP-Pro does not limit cores as long as they do not span more than two CPU's. My host machine has one CPU and four cores (eight if you consider the hyperthreading). KVM is presenting my XP-Pro guest multiple CPUs, not cores. XP will not use more than two CPUs by design. What I am after is a way to have KVM present my guest one CPU with four cores. Not four independent CPUs. I have attached /proc/cpuinfo from Fedora Core 16 guest, along with my /proc/cpuinfo from my host. What am I doing wrong?
