I have dual core Opteron 275 with AMD PowerNow! and frequency scaling.
This is how I boot xen:
kernel$ /boot/$ISADIR/xen.gz console=vga cpufreq=xen dom0_mem=3072M
dom0_vcpus_pin=false watchdog=false
but when I run xenpm this is what I get:
# xenpm
Xen cpuidle is not enabled!
[CPU0] failed to get max P-state
[CPU1] failed to get max P-state
[CPU2] failed to get max P-state
[CPU3] failed to get max P-state
Is power management supported (build 127)? Why am I getting this error?
Thank you in advance.
It could be that the hypercalls needed by xenpm aren't properly handled
by the dom0 kernel interface. The power management code isn't something
we have been using on our dom0 so far. I'll have a look at it.
Thanks for reporting this,
