I've been working with KVM for a while on SL5.5 for mostly Windows guests. Recently I've needed to run XP SP3 guests for legacy applications. However, when I set one up it maxes out the CPUs allocated to it, even when the guest CPU use is 2% or idle. Googling has only shown that it should support ACPI, which I checked and does have ACPI shown under computer in Device Manager of the XP guest.

Any ideas to get XP behaving as a guest with KVM?
