Open Stack

On an Ussuri Devstack, I would like to launch instances with ephemeral 
storage from Horizon and remove the volume storage switch from the 
instance launch dialog.

Prior to Train, the dialog was configured with the 
LAUNCH_INSTANCE_DEFAULTS dictionary in /local_settings.py/. This is my 
dictionary; I set /create_volume /to /False /and /hide_create_volume /to 
/True/:

LAUNCH_INSTANCE_DEFAULTS = {
     'config_drive': False,
     'create_volume': False,
     'hide_create_volume': True,
     'disable_image': False,
     'disable_instance_snapshot': False,
     'disable_volume': False,
     'disable_volume_snapshot': False,
     'enable_scheduler_hints': True,
}

Starting with Train, the dictionary is in 
/.../openstack_dashboard/defaults.py/, but the changes I made there have 
no effect. Adding the dictionary to /local_settings.py/ has no effect 
either.

To test whether /defaults.py/ is used at all, I added a syntactically 
incorrect line, and indeed, the syntax error is logged in 
/horizon_error.log/.

I wonder what I am doing wrong. I am convinced it worked like this on 
Stein. Any ideas?
