kvm erro no syslog diz rdmsr não manipulado cpu0

Question

Eu tenho um servidor que hospeda cerca de 20 máquinas guest KVM. O syslog é, às vezes, inundado de mensagens como estas:

00:17:36 vhost-server kernel: [ 157.835078] kvm: 3138: cpu0 unhandled rdmsr: 0xc0010112 Mar 28 00:17:36 vhost-server kernel: [ 157.835108] kvm: 3138: cpu0 unhandled rdmsr: 0xc0010048 Mar 28 00:17:36 vhost-server kernel: [ 157.999164] kvm: 3138: cpu0 unhandled rdmsr: 0xc0010001 Mar 28 00:17:37 vhost-server kernel: [ 158.378247] kvm: 3179: cpu0 unhandled rdmsr: 0xc0010112 Mar 28 00:17:37 vhost-server kernel: [ 158.378277] kvm: 3179: cpu0 unhandled rdmsr: 0xc0010048 Mar 28 00:17:37 vhost-server kernel: [ 158.551881] kvm: 3179: cpu0 unhandled rdmsr: 0xc0010001 Mar 28 00:17:39 vhost-server kernel: [ 160.474937] kvm: 3508: cpu0 unhandled rdmsr: 0xc0010112 Mar 28 00:17:43 vhost-server kernel: [ 164.335746] kvm: 3342: cpu0 unhandled rdmsr: 0xc0010112 Mar 28 00:17:43 vhost-server kernel: [ 164.335752] kvm: 3342: cpu0 unhandled rdmsr: 0xc0010048 Mar 28 00:17:43 vhost-server kernel: [ 164.502836] kvm: 3342: cpu0 unhandled rdmsr: 0xc0010001 Mar 28 00:17:44 vhost-server kernel: [ 165.198538] kvm: 3392: cpu0 unhandled rdmsr: 0xc0010112 Mar 28 00:17:44 vhost-server kernel: [ 165.198545] kvm: 3392: cpu0 unhandled rdmsr: 0xc0010048 Mar 28 00:17:44 vhost-server kernel: [ 165.364203] kvm: 3392: cpu0 unhandled rdmsr: 0xc0010001 Mar 28 00:17:53 vhost-server kernel: [ 174.093009] kvm: 3731: cpu0 unhandled rdmsr: 0xc0010112

As coisas parecem estar funcionando bem. Alguém tem alguma idéia do que é isso?

Não é um bug: echo 1 > / sys / module / kvm / parameters / ignore_msrs
