MAAS deploy Promox Image

I’ve been successfully deploying Ubuntu on MAAS-managed bare metal using Terraform-based pipelines without issues.

I’m now attempting to deploy Proxmox VE (Debian-based) on the same MAAS infrastructure, but the deployment is failing. The same hardware, networking, and storage configuration works reliably for Ubuntu images.

I’m looking to understand whether deploying Proxmox via MAAS is a supported or known pattern, and if there are any specific requirements or limitations (e.g. Debian image constraints, curtin storage layout expectations, boot mode, or post-deploy steps) that need to be accounted for.

Any guidance on recommended approaches or known pitfalls would be appreciated?
