2.6.39 dom0 xen power management test
Hi Konrad / Yu Ke,
I have tried konrad''s master tree:
commit 329408d788f62629131ea28c112e973878d52c9e
Merge: e370fe2 773f8cf
Author: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
Date: Thu May 19 14:37:32 2011 -0400
Merge branch ''linux-next''
With a xen-4.1.0 hypervisor, on my AMD x6 phenom.
Curious if Xen Power Management would work...
Output of all xenpm

[PATCH 0/2] Hyper-V synthetic interrupt controller
This patchset implements the KVM part of the synthetic interrupt
controller (synic) which is a building block of the Hyper-V
paravirtualized device bus (vmbus).
Synic is a lapic extension, which is controlled via MSRs and maintains
for each vCPU
- 16 synthetic interrupt "lines" (SINT's); each can be configured to
trigger a specific interrupt vector optionally with auto-EOI
