> In this example the override is part of a compute host definition and there it is in the host_vars section (compute_hosts -> 900089-compute001 -> host_vars -> override). Is it possible to apply such an override for all the compute hosts by not using the hostname? For instance something like:
> 
> " compute_hosts:
>        nova_nova_conf_overrides:
>          DEFAULT:
>            remove_unused_original_minimum_age_seconds: 43200
> "

You can set nova_nova_conf_overrides: into a file named /etc/openstack_deploy/user_variables.yml and it will apply on all your nodes.

If you want to be more surgical, you'd have to give more details about your OpenStack-Ansible version and what you're trying to achieve.
