MSRs are model specific and defined per model number. If you report a model number you're expected to implement the MSRs defined for that model number. AFAIK Xen just reports 0 for unknown MSRs (and I'm surprised KVM doesn't too) I would suggest to fix KVM. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
