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

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
