Hi, 
I am trying to use hypervissor based cpufreq, but unfortunately it doesn't work 
for me. 

xenpm get-cpufreq-para returns this:
[CPU0] failed to get cpufreq parameter
[CPU1] failed to get cpufreq parameter
[CPU2] failed to get cpufreq parameter
[CPU3] failed to get cpufreq parameter
[CPU4] failed to get cpufreq parameter
[CPU5] failed to get cpufreq parameter
[CPU6] failed to get cpufreq parameter
[CPU7] failed to get cpufreq parameter

How could I debug hypervissor based cpufreq in order to see what the problem 
is? Tried with cpufreq=verbose, but there is no any output regarding cpufreq in 
xm dmesg.

I am on Dell PowerEdge III with 2x Xeon E5450  @ 3.00GHz flashed with latest 
bios 2.7.0

xm dmesg returns this:
