git bisect told me:
c4a7dca92bbb9881a5d678720f1d0c2153499749 is the first bad commit commit c4a7dca92bbb9881a5d678720f1d0c2153499749 Author: Joerg Roedel <joerg.roedel@amd.com> Date: Fri Feb 10 18:05:05 2012 +0100
perf tools: Change perf_guest default back to false
Setting perf_guest to true by default makes no sense because the perf subcommands can not setup guest symbol information and thus not process and guest samples. The only exception is perf-kvm which changes the perf_guest value on its own. So change the default for perf_guest back to false.
