Hi Franck,

See the following Horizon configuration option: https://docs.openstack.org/horizon/latest/configuration/settings.html#launch-instance-defaults

Configure it via custom_local_settings in Kolla Ansible for Bobcat or earlier: https://docs.openstack.org/kolla-ansible/2023.2/reference/shared-services/horizon-guide.html

Note that the file name is changing in Caracal, which is why I am not linking to the latest documentation.

Hi,
With horizon, is it possible de have this default parameter when you create an instance: in source, create a new volume: « No ».
And.. if it’s possible, how configure this with kolla-ansible ?
Thank’s for your help.

Franck
