Suppressing kvm rdmsr errors to console

I am seeing numerous kvm rdmsr messages logged to /dev/tty1 (console), and would like to know how to suppress these messages. I've attempted "echo 1 > /sys/module/kvm/parameters/ignore_msrs" and the messages still appear on tty1.

I'm seeing the following rdmsr messages:
kvm [22212]: vcpu0 ignored rdmsr: 0x606
kvm [22212]: vcpu0 ignored rdmsr: 0x611
kvm [22212]: vcpu0 ignored rdmsr: 0x639
kvm [22212]: vcpu0 ignored rdmsr: 0x641
kvm [22212]: vcpu0 ignored rdmsr: 0x619
kvm [22212]: vcpu0 ignored rdmsr: 0x1ad
