?! This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4. Hi avi, Can you give some suggestion how to verify this bug. no stable step to get message: "9480: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x130079" Thanks Suqin Starting a Linux guest should work, perhaps need to 'info registers' to trigger it. update the component to kernel according to the patch in comment0 This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux release for currently deployed products. This request is not yet committed for inclusion in a release. Posted patch to RHEL6.4 on 07/31/2012: [RHEL6.4 PATCH][x86] KVM: Don't save/restore MSR_IA32_PERF_STATUS Patch(es) available on kernel-2.6.32-301.el6 Test with qemu-kvm-0.12.1.2-2.340.el6.x86_64: we won't see following message any more: "9480: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x130079" however we still get: kvm: 6149: cpu0 unhandled wrmsr 0x40000000 data 0 kvm: 6149: cpu0 unhandled rdmsr 0x40000000 Hope this is enough to verify the bug.
