Re-Hi,
with that CPU you should have no problems with Xen-internal cpufreq management.
This
would be - as you might know - switched on by providing cpufreq=xen in the Xen
line
of grub.
The provided ondemand governor will recognize the complete load of the system,
what
you can easily test by createing load with e.g. bzip2 in a DomU. You''ll
see that your
CPU will certainly step up. With your CPU, you might have problems to create the
load,
though ;-).
BR,
Carsten.

Betreff: [Xen-users] which governor for cpufreq?
Hi!
What a cpufreq governor does make sense? (someone says ondemand doesnt
make sense because it ''see'' only the dom0 demand)
System is an i7 with cpufreq in hypervisor
