To support Flatcar, we must ensure that Proxmox can load the ignition data into the VM.

Anything else you would like to add:

we have a way of injecting an ISO into the VM; while providing ignition data.

Environment:

• Cluster-api-provider-proxmox version:

• OS (e.g. from /etc/os-release):

Hi, thanks for working on this. I am a Flatcar maintainer and I am involved on Cluster API topics too. For Flatcar support to work, we first need to get Ignition Proxmox support. You can track this here: flatcar/scripts#1783 (cross-ref: flatcar/Flatcar#1040)

@tormath1 yes, I know that,
However, I'm also trying to do some hacks by injecting an ISO as config-2 with the OpenStack provider.
don't know if that works though.

What are your hacks? For what is worth, Flatcar + CAPO works fine at the moment. Feel free to join the Flatcar Matrix channel or #flatcar channel on Kubernetes Slack to discuss about this more interactively (https://github.com/flatcar/flatcar?tab=readme-ov-file#chat)

networkd config should be adjusted so it can support our current features:
