kvm-84: unhandled rdmsr: 0xc0010117
March 15, 2009 - 7:42pm
Hi,
I'm using kvm 84 on Linux kernel 2.6.26 on a Intel Xeon X3320 system and I get a lot of those messages in the kernel log:
[18859.245127] kvm: 4955: cpu0 unhandled rdmsr: 0xc0010117
[18859.245127] kvm: 4955: cpu0 unhandled wrmsr: 0xc0010117 data 0
...
kvm seems to run fine though afaics.
Is this just a harmless message or something to worry about?
mbiebl,
According to the kvm maintainers those messages are harmless and should have been fixed in kvm-83. See the following mailing list thread.

Hi Haydn,
thanks for the link. As I wrote, I'm using kvm-84, so either this issue has not been fixed in 83 or I have a different problem.
Cheers,
Michael
We have the same problem using kvm-84 on an Ubuntu Server 9.04.
$ uname -a
Linux my-host 2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:45:36 UTC 2009 x86_64 GNU/Linux
The server is a quadri-core "Intel(R) Xeon(R) CPU X3360 @ 2.83GHz".
I was told by a Red Hat gut at the kvm-devel mailing list, that this message is harmless. Just ignore it.

Same "warning" here. My guest instance seems to run fine.
