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. add support for new APIs into libvirt-python library.
Changes since v1:
* change perf APIs implementation to match new style of the API.
* add new xml element
* reenable all perf events previously enabled when libvirtd daemon
restart.
* redesign perf util functions.
Changes since v2:
* add an example XML file to the test suite.
* add virPerfReadEvent().
* change 'perf' xml element to new style.
* change 'perf' command to new stype.

perf: add new public APIs for perf event
perf: implement the remote protocol for perf event
perf: implement a set of util functions for perf event
qemu_driver: add support to perf event
perf: add new xml element
perf: reenable perf events when libvirtd restart
virsh: implement new command to support perf
virsh: extend domstats command
