[libvirt] [PATCH 0/8] Add perf and Intel CMT feature support

The series mainly adds Intel CMT feature support into libvirt. CMT is new introduced PQos (Platform Qos) feature to monitor the usage of cache by applications running on the platform. Currently CMT patches has been merged into Linux kernel mainline. The CMT implementation in Linux kernel is based on perf mechanism and there is no support for perf in libvirt, and so this series firstly add perf support into libvirt, including two public API and a set of util interfaces. And based on these APIs and interfaces, thie series implements CMT perf event support. TODO: 1. This series relys on keeping an open file descriptor for the guest. We should add one patch to call sys_perf_event_open again iff libvirtd is restarted.
