Host-model CPU definitions (and domain capabilities) will use the original CPU models (without noTSX in their name) and explicitly disable hle and rtm features. This way domains with host-model CPUs will be migratable even to older versions of libvirt which do not support the noTSX model variants. The new models will be advertised in host capabilities and they may be used explicitly with custom CPUs.
