Hi,

I want to use xenoprof to profile the overhead of the hypervisor.�
I patched the oprofile-0.9.5 using the patch from�xenoprof.sourceforge.net

Debian GNU/Linux 5.0 (lenny)
Xen-4.0.1 + 2.6.32.27 (linux-2.6-pvops.git) Dom0
My platform is Intel(R) Core(TM) i7 CPU � � � � � 960 �@ 3.20GHz

My problems are:
In Dom0, �But hardware performance counters don't be mounted�

after initialization (opcontrol --init)

# ls /dev/oprofile

backtrace_depth � �cpu_buffer_size � pointer_size

buffer �� cpu_type � � � � � �stats�

buffer_size � � � � � � dump � � � � � � � �time_slice�

buffer_watershed � �enable

0(and 1,2,3) directories are not exist.

Is there any reason for this ?
