Could it be that your guest image uses instructions that are only available on AMD processors? Or is this a regression from previous KVM versions. If yes, which one worked? Further questions in that case: - Could you retest with KVM over a 3.3 kernel, i.e. without kvm-kmod? Does that also faile? - What is your host kernel version?
