Hello,
Does it exist some documentation concerning following topic ?
What's difference between following perf counters :
/cgroup/cpuacct/libvirt/qemu/test/cpuacct.usage
and
/cgroup/cpuacct/libvirt/qemu/test/emulator/cpuacct.usage
I don't know from the top of my head whether the accounting is effective for all tasks
in the current group (i.e. /test/cpuacct.usage only accounts for /test/tasks) or also
subgroups. Anyway, if the second is true (which I think it is), then /test/emulator is
only accounting for the emulator thread and the upper one is for emulator, all vCPU
threads and I/O threads.
