Has anyone had any success getting WinXP 32bit to use 4 CPU's under Centos 5.5 KVM?
I have tried everything and the best I can get is 2 CPU's. I tried everything listed here http://www.linux-kvm.com/content/running-windows-smp-guests I am using the VIRTIO drivers.
As it is discussed in the comments on the page you have linked above, XP only supports 2 CPUs but more cores.
AFAIK KVM will always emulate CPUs not cores.
