Hi,
I built a small community project for something I kept missing after moving Windows workloads to Proxmox: take a golden-image template, clone it, and customize the guest (hostname, network, timezone/locale, workgroup or AD join) with Sysprep — roughly in the spirit of VMware guest customization.
It runs as Docker Compose (or Podman with Compose v2), talks to PVE over the API, and drives the guest through the QEMU guest agent. There’s a web UI and a machine API. Current release is 2.5.1. Lab-tested on Windows Server 2019 and Windows 11.
Also included if useful: bulk Win11 desktop batches with quotas/caps, reusable Customization Specs, lifecycle tags on the VM in PVE, pre-built amd64 images on GHCR, and install docs that spell out required .env / privileges.
Not an official Proxmox product — MIT for the sidecar; optional PDM UI fork is separate/AGPL.
Repo / install: https://github.com/RobertLukan/proxmox-guestos-customization
Release: https://github.com/RobertLukan/proxmox-guestos-customization/releases/tag/v2.5.1
Note: AI helped with coding/docs; I own the design, review, and lab validation.
Happy to hear your thoughts.
