No, this is not a host issue. This is a KVM issue which needs to be fixed in the KVM module. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. commit 9170170007aa8886583ada73c0ea1122231c708a Author: Zachary Amsden <zamsden> Date: Thu Jan 27 16:57:31 2011 -0500 Patches are in RHEL6 tree... This is already commited and in the tree... I tagged it with the wrong buzilla number apparently.

Can not find core Phenom II CPU host. Tried on Dual-Core AMD Opteron(tm) Processor 1216 instead. Tried both kernel-2.6.32-71.el6 & kernel-2.6-32-130.el6 with the steps in comment #0, Actual Results: guest works fine with -smp 2,I can not reproduce this issue on both 2 kernels . bcao---->ikent Hi,Ian Could you help verify it on core Phenom II CPU host ? thanks, Mike I tested kernels 2.6.32-71.el6 and 2.6-32-130.el6 on F14. The test consisted of setting an F14 VM to use 2 CPUs and then booting the VM, shutting it down followed by booting it again, then setting the CPUs to 1 and booting the VM, timing each by using date. The definition of "booting" was from the time the run triangle was pressed until the login screen was presented. The results were: Kernel: 2.6.32-71.el6.x86_64 2 CPUs: Start: Mon Apr 18 17:10:19 WST 2011 Finish: Mon Apr 18 17:24:25 WST 2011 1 CPU: Start: Mon Apr 18 17:30:36 WST 2011 Finish: Mon Apr 18 17:31:14 WST 2011 Kernel: 2.6.32-130.el6.x86_64 2 CPUs: Start: Mon Apr 18 17:41:18 WST 2011 Finish: Mon Apr 18 17:41:50 WST 2011 1 CPU: Start: Mon Apr 18 17:43:09 WST 2011 Finish: Mon Apr 18 17:43:41 WST 2011 Ian ,thanks very much ! Referring to comment #14 ,the issue was reproduced on kernel 2.6.32-71.el6.x86_64 and verified on kernel 2.6.32-130.el6.x86_64 Based on bove ,move status to VERIFIED.
