Now LBT feature is added in kvm mode, not supported in TCG mode since it is not emulated. Feature variable lbt is added with OnOffAuto type, If lbt feature is not supported with KVM host, it reports error if there is lbt=3Don command line. If there is no any command line about lbt parameter, it checks whether KVM host supports lbt feature and set the corresponding value in cpucfg.

Use OnOffAuto type variable pmu to check the PMU feature. If the PMU Feature is not supported with KVM host, it reports error if there is pmu=3Don command line. If there is no any command line about pmu parameter, it checks whether KVM host supports the PMU Feature and set the corresponding value in cpucfg.
