Adrian:
'perf kvm stat live' command fails on Linus' latest tree: $ perf kvm stat live Failed to parse sample
git bisect points to:
75562573bab35b129cfd342fc2bcf89da84a6644 is the first bad commit commit 75562573bab35b129cfd342fc2bcf89da84a6644 Author: Adrian Hunter <adrian.hunter@intel.com> Date: Tue Aug 27 11:23:09 2013 +0300
perf tools: Add support for PERF_SAMPLE_IDENTIFIER
Enable parsing of samples with sample format bit PERF_SAMPLE_IDENTIFIER. In addition, if the kernel supports it, prefer it to selecting PERF_SAMPLE_ID thereby allowing non-matching sample types.

perf_evlist__event2evsel() is failing. From what I can see the problem is that evlist->heads is not getting populated. This command does not read/write files but processes events as they come in. I have another similar command that is also breaking for the same reason.
