Require solution for "xenoprof: Initialization failed. Intel processor model 44 for P6 class family is not supported“

HI all :
          I got the message "Using timer interrupt." when trying the command
"opcontrol --list-events". then I found infomation "xenoprof: Initialization
failed. Intel processor model 44 for P6 class family is not supported“ after
"xm dmesg".  the TYPE OF CPUS here is Intel(R) Xeon(R) CPU  E5620  @
2.40GHz.
         So does it really not support this type of processor  and is there
any fix that may solve it ？ need help...

.
Thanks~

This CPUs work fine for me with 4.1.1.

You need to provide more details. Is this 3.0? 2.6.39? What version of Xen hypervisor?

Hi Konrad:
    the version of Xen hypervisor is 3.4.3 and the version of kernel is
2.6.18.  I don't know why it works well in physical machine and fails
in virtual machine ?

Because virtual machines aren't allowed to have direct access to host
performance counters; the VM has to ask Xen to do it.  Performance
counters are very specific to individual processor models; so Xen
needs support for specific processor models for the guest to be able
to use performance counters rather than simply using a timer
interrupt.  Those changes are typically not backported to older
releases (although there's no reason maintainers couldn't do so if
they chose.)
