Then when you ask for "architecture=ppc64" it should land on > that node. you know it says it for arm but you might be able to do this by setting hw_machine_type https://github.com/openstack/glance/blob/master/etc/metadefs/compute-libvirt-image.json#L34 i know you can set the hw_machine_type to set teh default for all instace on a host https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.hw_machine_type but i can rememebr it image property is alys used or if its just used for arm as the docs suggest. the hypervisor_type in the image should be set to qemu to make sure you avoid the kvm hosts as they will not work for cpu emulation. > > If this is for "development, testing or migration of applications to > Power" have you checked out these people?
