2.6.38.2 kernel, trace-cmd 3e8b5b8 which is March 18 (though git pull
done this morning).
For grins I checked-out 9cce1c9b5b and same error:
trace-cmd record -e kvm -- sleep 1
trace-cmd report 2>&1 | less
You do have to put stderr onto stdout to see the messages I reported
earlier. Or look for [FAILED TO PARSE] on the kvm_exit and
kvm_emulate_insn lines.
