you know it says it for arm but you might be able to do this by setting <br>
hw_machine_type <a href="https://github.com/openstack/glance/blob/master/etc/metadefs/compute-libvirt-image.json#L34" rel="noreferrer" target="_blank">https://github.com/openstack/glance/blob/master/etc/metadefs/compute-libvirt-image.json#L34</a><br>
i know you can set the hw_machine_type to set teh default for all instace on a host<br>
<a href="https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.hw_machine_type" rel="noreferrer" target="_blank">https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.hw_machine_type</a><br>
but i can rememebr it image property is alys used or if its just used for arm as the docs suggest.<br>
<br>
the hypervisor_type in the image should be set to qemu to make sure you avoid the kvm hosts as they will not work<br>
for cpu emulation.<br>
