ignore_msrs for host CPU being ignored

[wmelnick]

I have 2 Proxmox 5.1 servers which are running "host" CPUs on one of the VMs. I have the kvm.ignore_msrs in place and even tried doing it manually with echo 1 > /sys/module/kvm/parameters/ignore_msrs and it is still clogging up dmesg.

How do I get the rdmsr entries to stop appearing in my logs?

Thanks in advance,
Warren

Hi,
Use instead 'host' cpu type, the name of the host cpu as cpu type.

find how to solve this spam messges from dmesg

echo 1 > /sys/module/kvm/parameters/ignore_msrs
echo 0 > /sys/module/kvm/parameters/report_ignored_msrs

or as permanent

/etc/modprobe.d/kvm.conf
options kvm ignore_msrs=Y
options kvm report_ignored_msrs=N

this work with latest kernel - did not test with other

i find this with
