Hi jiri,

Thanks for you kindly reviewing, I wonder what cpu/cpu_map.xml does in libvirt if QEMU already provide all features to guest?

              NACK. We don't add features to models since it could break
              existing setups. In any case, presence of any flag in CPU models
              does not really influence whether that flag is going to be provided
              to a guest. That part is driven by QEMU.
