The hook is within the action. However your proposal seems much more clean. This could be even implemented in the generic tm\_mad driver (here: [https://github.com/OpenNebula/one/blob/master/src/tm\_mad/one\_tm.rb#L99](https://github.com/OpenNebula/one/blob/master/src/tm_mad/one_tm.rb#L99)) Although this would need some minimal support from oned.
