Date: Fri, 1 Jun 2012 19:26:28 +0530	[thread overview]
Message-ID: <20120601135627.GA3004@linux.vnet.ibm.com> (raw)

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]#
