As Chris mentioned, we are using a host label to drive this configuration on a per worker basis. If you want to enable this configuration for a specific openstack worker: $ system host-lock compute-0 $ system host-label-assign compute-0 remote-storage=enabled $ system host-unlock compute-0 If you look at the nova plugin, this configuration is set via a per-host override based on the host label. Your nova.yaml is setting the default configuration not the per-host configuration. I suspect that if we weren’t setting the per-host override for this value explicitly in the nova plugin based on the presence/absence of the label, then this value would apply to all nova pods across all the compute workers.

This allows the rbd_pool and rbd_cev_conf settings to be configured properly as well.

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?
