Almost all of your recommendations are included in this update. I haven't got a chance to test on qemu yet, but this patch fixes access to MSR per your recommandation, so should be fine. I'm in process of making similar changes to kvm/Qemu that i will send once I have learned to build test it :-). Historically machine checks on Intel X86 processors have been broadcast to all logical processors in the system. Upcoming CPUs will support an opt-in mechanism to request some machine checks delivered to a single logical processor experiencing the fault. For more details see Vol3, Chapter 15, Machine Check Architecture. Modified to incorporate feedback from Boris on V1 patches.
