On s390 machines host-passthrough and host-model CPUs result in the same guest ABI (with QEMU new enough to be able to tell us what "host" CPU is expanded to, which was implemented around 2.9.0). So instead of using host-passthrough CPU when there's no CPU specified in a domain XML we can safely use host-model and benefit from CPU compatibility checks during migration, snapshot restore and similar operations.
