Otherwise, "query-machines" will indicate the wrong CPU model ("qemu-s390x-cpu" instead of "host-s390x-cpu") as "default-cpu-type". Doing a {"execute":"query-machines"} under KVM now results in {"return": [ { "hotpluggable-cpus": true, "name": "s390-ccw-virtio-4.0", "numa-mem-supported": false, "default-cpu-type": "host-s390x-cpu", "cpu-max": 248, "deprecated": false}, { "hotpluggable-cpus": true, "name": "s390-ccw-virtio-2.7", "numa-mem-supported": false, "default-cpu-type": "host-s390x-cpu", "cpu-max": 248, "deprecated": false } ...
