[Daniele Santoro]

I’m 99% sure you can’t modify the cloud-init script already associated with an instance from the UI. An idea could be to see in the vm this folder (if present): /etc/cloud/, probably you can modify some scripts from there. Also be aware that the cloud-init script is started with an upstart job present in /etc/init.d/cloud-init*.

Anyway, my suggestion is: try to create a snapshot of your instance and then boot up a new instance from the image/snapshot previously created. Before booting the image you can configure your cloud-init script from the UI.

Best,
Daniele
