Hi and thanks for the response. I ran the commands you mentioned and got the following:
[jonathan@dom0 ~]$ lsmod | grep xen_acpi_processor xen_acpi_processor 20480 0 [jonathan@dom0 ~]$ xenpm get-cpufreq-para cpu id : 0 affected_cpus : 0 cpuinfo frequency : max [2701000] min [400000] cur [2700000] scaling_driver : acpi-cpufreq scaling_avail_gov : userspace performance powersave ondemand current_governor : ondemand ondemand specific : sampling_rate : max [10000000] min [10000] cur [20000] up_threshold : 80 scaling_avail_freq : 2701000 2700000 2500000 2200000 1900000 1600000 1300000 1000000 700000 *400000 scaling frequency : max [2700000] min [400000] cur [400000] turbo mode : enabled [CPU1] failed to get cpufreq parameter Appreciate any help in interpreting the above!
