Re: [libvirt] [PATCH 34/36] vircpuhost: Add support for reading MSRs

The new virHostCPUGetMSR internal API will try to read the MSR from
/dev/cpu/0/msr and if it is not possible (the device does not exist or
libvirt is running unprivileged), it will fallback to asking KVM for the
MSR using KVM_GET_MSRS ioctl.
Is there benefit to using /dev/cpu/0/msr, instead of always using
/dev/kvm ?
