Replying to an old thread because this one popped up in a search.
There is an open source and locally running ignition/combustion generator that I've used on bare metal. To use it with XCP-ng, we would need the ability to have a second "cd rom" drive during the install phase, one for the OS installer, one for the combustion/ignition ISO generated from the tool.

They say it only runs locally, no info is send out to the web. I didn't monitor my connection on the one time I used it, and probably won't the next time (coming soon to a bare metal cluster in my lab). For the record, I'm using the LEAP version of Micro for my tasks.
