[fedora-virt] Different cpu usage between Fedora and SL6 guests

While staring at top on my SL6 kvm server waiting for it to crash, I noticed 
that my idle Fedora kvm guests appear to be consuming between 8-12% cpu while 
my idle SL6 guests appear to be consuming between 0.3-2% cpu as shown in the 
qemu-kvm processes in top.  In fact I have a Fedora 17 instance running now 
with nothing but kernel processes and the qemu-kvm process still shows it 
using 7-8% cpu.

Does anyone have any insight as to why this would be the case?
