This is the libvirt's part of the changes related to CVE-2017-5715. The new models can be used to pass the protective CPU features to guests. But remember, the host CPU microcode, host kernel, QEMU, and libvirt all need to be updated for this to be any useful.
Based on a patch from Paolo Bonzini.
You likely also want this pre-requisite series for libvirt: https://www.redhat.com/archives/libvir-list/2018-January/msg00114.html This ensures libvirt's cache of QEMU CPU model info is updated when the host CPU microcode changes. Without that patch, libvirt might not pick up the changed QEMU CPU models if the microcode update RPM was installed after the updated QEMU RPM.
See QEMU patches from Eduardo for more details: https://patchew.org/QEMU/20180109154519.25634-1-ehabkost@redhat.com/
