s390x/kvm: Set default cpu model for all machine classes
We have to set the default model of all machine classes, not just for
the active one. 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
} ...
Libvirt probes all machines via "-machine none,accel=kvm:tcg" and will
currently see the wrong CPU model under KVM.
