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?
