[Xen-devel] OProfile with Xen-4.9


I have installed Xen-4.9 from Ubuntu 17.10 package. And I would like to profile 
it with OProfile (as far as I know this is the only option).

With instruction from  
 I have been able to build oprofile-0.9.4. There were some bugs ( 
https://patchwork.ozlabs.org/patch/679925/ ,  
https://sourceforge.net/p/oprofile/mailman/message/30135604/ ,  

With `opreport -t 2` I receive:
> opreport error: No sample file found: try running opcontrol --dump
> or specify a session containing sample files

With `more /proc/interrupts |grep NMI` I get:
> NMI:          0          0          0          0          0          0        
>   0          0   Non-maskable interrupts

Could somebody point me to some good instruction for profiling current version 
of Xen?

P.S. I have rebuild package with  Performance Counters and  Performance 
Counters Array Histrograms already.

With best regards
