Description of problem: Every time I start a virtual machine on my barcelona-based DL785 I see these messages on the console: kvm: 18879: cpu0 unimplemented perfctr wrmsr: 0xc0010004 data 0x0 kvm: 18879: cpu0 unimplemented perfctr wrmsr: 0xc0010000 data 0x130076 kvm: 18879: cpu0 unimplemented perfctr wrmsr: 0xc0010004 data 0xffffffffffdce750 kvm: 18879: cpu0 unimplemented perfctr wrmsr: 0xc0010000 data 0x530076 Is this a real problem or debug noise?

*** This bug has been marked as a duplicate of bug 507085 ***
I can't access bug #507085. Is it safe to ignore these messages for now?
I have the same problem and I can't access bug #507085 too... Can I have more informations on this? It's really a blocker bug here cause our guests VM crash just after seeing this in the log.
I am seeing the same issue on HP DL380 G5 The following appears on the console output, doesn't appear to affect anything other than make me think something is wrong kvm: 14273: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x130079 kvm: 14273: cpu0 unimplemented perfctr wrmsr: 0xc1 data 0xffd4c44c kvm: 14273: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x530079 kvm: 14273: cpu1 unimplemented perfctr wrmsr: 0x186 data 0x130079 kvm: 14273: cpu1 unimplemented perfctr wrmsr: 0xc1 data 0xffd4c44c kvm: 14273: cpu1 unimplemented perfctr wrmsr: 0x186 data 0x530079 We are running RHEL 5.4 kernel 2.6.18-164.2.1.el5 kvm-83 Would be nice to be able to see bug #507085 to give us some idea of the progress on this.
sony vaio z720d with fedora12 x86_64 - updated daily. was trying to do an oracle db upgrade to a 2 node RAC when it crashed in the middle. its reproducable: Jan 26 12:08:46 laptopmarafa kernel: kvm: 9067: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x130079 Jan 26 12:08:46 laptopmarafa kernel: kvm: 9067: cpu0 unimplemented perfctr wrmsr: 0xc1 data 0xffd97008 Jan 26 12:08:46 laptopmarafa kernel: kvm: 9067: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x530079 Jan 26 12:42:24 laptopmarafa kernel: kvm: 9067: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x130079 Jan 26 12:42:24 laptopmarafa kernel: kvm: 9067: cpu0 unimplemented perfctr wrmsr: 0xc1 data 0xffd97008 Jan 26 12:42:24 laptopmarafa kernel: kvm: 9067: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x530079 Jan 26 12:42:24 laptopmarafa kernel: kvm: 9099: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x130079 Jan 26 12:42:24 laptopmarafa kernel: kvm: 9099: cpu0 unimplemented perfctr wrmsr: 0xc1 data 0xffd97008 Jan 26 12:42:24 laptopmarafa kernel: kvm: 9099: cpu0 unimplemented perfctr wrmsr: 0x186 data 0x530079 12.08 and 12.42 are the times of the 2 crashes today
