[Xen-users] how to get QEMU detailed breakdown in Oprofile?

[Songtao Liu <songtao.liu@xxxxxxxx>]

Hi,

as now i am doing profiling and found that the QEMU should be one of the major 
reason for the low network throughput on HVM Guest.

In order to know details about it, it will be better to get the breakdown of 
QEMU in Oprofile. 

As see from the following results,there is only two breakdowns, how can I run 
the oprofile to get more detailed QEMU informations?

 29933 12.5726 qemu-dm
         DTLB_MISSES:5000|
          samples|      %|
        ------------------
            20991 70.1266 qemu-dm
             8942 29.8734 anon (tgid:3608 range:0xdf3000-0xdf4000)


Thanks
Songtao
