KVM has a whitelist of MSRs that it handles. These messages show
that the guest has been doing reads on various MSRs that KVM does
not support. These can sometimes be the the cause of bugs, but
others may be harmless. Best to report these to the KVM community,
with details about your host hardware CPU models, and what guest
OS you are running

Daniel
