Hi all, I’m working on adding Ubuntu 24.04 (Noble) support to the virt-builder template generator, and I’d appreciate feedback on the proposed approach. Ubuntu 24.04 no longer publishes the Debian Installer tree used by the existing virt-install/preseed path. This RFC imports a dated Canonical Noble cloud image, verifies its pinned SHA-256, converts it to raw, and then reuses the existing inspection, sysprep, compression, and index-generation stages. Existing installer-based templates remain unchanged. I tested this end to end on Ubuntu 24.04. The focused catalog/import tests, shell syntax, OCaml parsing, XZ integrity, and generated-index checks passed. The generated image had an empty machine ID, no SSH host keys or stale cloud-init state, and a locked root account. I have not run the full repository make check because this checkout lacked the generated Autotools bootstrap files. I’d especially appreciate your thoughts on: - Using a pinned dated image versus SimpleStreams - Preserving Noble’s native virtual size and cloud-init behavior - The expected BIOS/UEFI boot validation before publication Public branch: https://github.com/aravindsivamani/guestfs-tools/tree/ubuntu-24.04-cloud-... The patch is attached. Thanks for taking a look!
