http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1672 Summary: xenpm start, statistics displayed incorrectly. Product: Xen Version: unstable Platform: x86 OS/Version: Linux-2.6 Status: NEW Severity: major Priority: P2 Component: Hypervisor AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: dkar4700@xxxxxxxxxxxxxxxxx The processor is an Intel quad core processor, first three cores are running on ondemand and the remaining core is running on powersave govenor. To get the average cpu frequency â??xenpm start 5â?? command was executed ( Results are list below ). Although the cpu 3 is running on lowest frequency which is P11 100%, the Avg Frequency is reported as 2199360 Hz. There is only one vm running with 4 vcpus. All 4 cores are utilized evenly while stats were gathering. 1)If cpu 3 was running 100% on P11 state the average cpu frequency should be around 1197000 ? ( If the reported figure is correct, could someone please shed some light on how it is calculated ) 2)The notation is also should also be on Hz not KHz on the average Freq ? Please let me know if anymore information is necessary.
