Hello
perf kvm generats segfaults while reporting events.
host & guest: 3.4.0-rc4
1) Copied kallsyms, modules from guest to host.
2) recorded events on host and guest & report it using below commands.
[root@host]# ./perf kvm --host --guest --guestkallsyms=/tmp/guest-kallsyms --guestmodules=/tmp/guest-modules record -a -o perf.data
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.381 MB perf.data (~16659 samples) ]
[root@host]# ./perf kvm --host --guest --guestkallsyms=/tmp/guest-kallsyms --guestmodules=/tmp/guest-modules report -i perf.data --force
perf: Segmentation fault
[root@host]#
