Hi
I''m running Debian Lenny with Xen 3.4 packages taken from Debian
Squeeze. I want to get power management to work in the hypervisor:
user@host:~$ sudo xenpm set-scaling-governor ondemand
[CPU0] failed to set governor name
user@host:~$ sudo xenpm get-cpuidle-states
Max C-state: C7
cpu id : 0
total C-states : 2
idle time(ms) : 1885922
C0 : transition [00000000000000429120]
residency [00000000000000186144 ms]
C1 : transition [00000000000000429120]
residency [00000000000001882392 ms]
user@host:~$ sudo xenpm
user@host:~$
No output at all? Maybe my CPU is not supported by Xen? The P-States are
correctly detected by Debian Lenny''s standard (non-xen) kernel.
user@host:~$ cat /proc/cpuinfo

I have tried setting cpufreq=xen explicitly but that does not seem to
make any difference. Does anyone have an idea what''s wrong here?
Cheers,
Birger

Unfortunately I still cannot get power management to work. Xen 3.4.1 has cpuidle and cpufreq=xen enabled by default. I have not set any boot parameters to Xen (but I also tried "cpufreq=xen cpuidle"), so power management should be enabled. I''m not sure how I can tell whether power management is or not. At least xenpm doesn''t work, so I''m assuming neither is power management. Power management works with the standard Debian Etch kernel using the powernow_k8 module so power management works in general, it just does not work in Xen. xenpm get-cpuidle-states reports max c-state c7 but strangely only lists c0 and c1: Max C-state: C7 cpu id : 0 total C-states : 2 idle time(ms) : 1962951 C0 : transition [00000000000000439633] residency [00000000000000150633 ms] C1 : transition [00000000000000439633] residency [00000000000001959380 ms] xenpm get-cpuidle-states outputs nothing at all and trying to set a governor results in [CPU0] failed to set governor name. I also don''t see any c-state related output in xm dmesg.

Did you enable this ACPI option in your dom0 config file? - Hui Birger Brunswiek wrote:> Stefan Kuhne wrote: > >> Birger Brunswiek schrieb: >> >> >>> Hi >>> I''m running Debian Lenny with Xen 3.4 packages taken from Debian >>> Squeeze.
