Intel PCM - suspends right after executing

Hi,
I try to execute PCM on Xen Server. It outputs 2 lines and it stops:
[bash][root@xenserver-kgprsyak pcm]# ./pcm.x 1 Intel Performance Counter Monitor Copyright (c) 2009-2011 Intel Corporation [/bash]
Do you have any clue why it doesn't work?

Hi,

Usually virtualization hypervisors (Xen) forbid direct low-level access to hardware performance counters through model specific registers inside guests. Usage of PCM with Xen is not supported. However, Ihad expected an error message from PCM (but you did not have any).

Thanks,

Roman
