[Ren, Qiaowei]

Hi, Daniel and Jiri,

Do you have more comments about this new version? I guess that it should fix those comments on previous version. ^-^

Thanks,
Qiaowei

> 
> The series mainly adds Intel CMT feature support into libvirt. CMT is new

> 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.
