Just a heads up. After installing libvirt rpms of this branch all my existing kvm s390 domains ended up with

Newly defined domains without specified cpu do so as well.
Unless the domains are all TCG, it seems your QEMU is too old. You need a fairly recent one which contains commit v4.1.0-1683-gde60a92ea7 (s390x/kvm: Set default cpu model for all machine classes)
I the domains all use KVM and you have new enough QEMU, there might be a bug somewhere. Which should not happen :=)
So shouldnt libvirt fence this rework (add default model) to qemu 4.2 and newer?
