Hello all,
There used to be perf scripts to do exit-level profiling of VMs
(number of exits, time spent per exit, etc). I am using kernel version
3.19, and the perf utility which ships with it has a perf-kvm option, but
that only reports total number of exits, and not the reason/latency.
The stats in /sys/debug/kvm seem to be about number of exits only,
not the time information. My question is: whats the most convenient way to
get per-exit counts and durations?
Thanks,
