Why is kvm_emulate_halt being executed from KVM_MP_STATE_INIT_RECEIVED/KVM_MP_STATE_SIPI_RECEIVED again? Why is it not true that the only valid transition from KVM_MP_STATE_HALTED is from KVM_MP_STATE_RUNNABLE? It would be good for KVM_MP_STATE_HALTED to indicate "guest executed HLT instruction" (which is impossible without INIT/SIPI being received). -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
