How to stop warnings "kvm: vcpu0 ignored rdmsr"

[mfoerster]

Hi,

when I set the CPU type on a virtual machine to "host", I get an error messages like "kvm [2745]: vcpu0 ignored RDMSR: 0x1c9" after each reboot of the virtual machine.
I have read that these messages do not mean much.

Does anyone know how to suppress this warnings?

I have already tried:

echo 1> / sys / module / kvm / parameters / ignore_msrs
and
echo "options kvm ignore_msrs = Y" >> / etc / modprobe.d / kvm.conf && update-initramfs -u -k all

Both unsuccessfully.

Thank you very much.

Regards
Mark

Necroing this thread just to have the solution registered in the forums.

To suppress the "ignored rdmsr" and "ignored wrmsr" outputting to logs, add "options kvm report_ignored_msrs=0" to your kvm configuration at /etc/modprobe.d/kvm.conf
