Hi everyone,
I am using libvirt 2.5.0. I'd like to enable the "perf events" to monitoring my vm performance such as l3 cache. But it failed with "error: argument unsupported: unable to enable host cpu perf event for cmt".
1. Could you please give some hints on how to check if my host CPU supports cmt,mbm, is it displayed in /proc/cpuinfo?
2. Does the kernel version matters as well to support it?
Thanks,
Hui
