My case was way more extreme, one core pretty much fully used by ksmd.
It was with late F14, just before the release of F15.

Yes, I eventually found out how to disable ksmd. I think that's not the
point, the point is that kvm/qemu/virt-manager could be improved in the
usability department. And that means it should do a reasonable job
without the user first modify lots of tunables.

virt-manager has gone a long way of making qemu/kvm a lot more useable,
but there's still room for improvements:

- I had occasional problems with the keyboard mapping

- Storage management is not always logical to me, I didn't find out how
to reuse an existing qcow2 image, so in the end I edited config files

- USB is not really workable. Trying it just now with up2date F15
crashed qemu (guest rawhide) when trying to assign a host USB device to
the guest
