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.
