Here is my nova.yml file. conf: nova: libvirt: images_type: rbd I can find 'images_type: rbd' in /etc/nova/nova.conf in every container about nova but in nova-compute I just find 'images_type: default'. My system is virtual standard with controller storage r2.0 following the guide(https://docs.starlingx.io/deploy_install_guides/current/virtual_controller_s...). I don't understand why this happened. Can anyone give me some help? Thanks Hu Tianhao
