[RFC PATCH guestfs-tools] builder: templates: Add Ubuntu 24.04 cloud image support

by Aravind Sivamani (asivaman)

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!

[PATCH nbdkit] indexed-gzip: Fix restart at non-byte-aligned access points

by Håkan Djurberg Johansson

This fixes a reproducible indexed-gzip failure when random access resumes at a non-byte-aligned access point. Without the patch, a gzip-compressed full-disk image exposes its GPT successfully, but filesystem reads fail repeatedly with |Z_DATA_ERROR (-3)|. With the patch applied to the same nbdkit source commit, the ext4 partition mounts read-only and file reads succeed. The corresponding GitLab issue is: nbdkit#32 <https://gitlab.com/nbdkit/nbdkit/-/work_items/32> A detailed unpatched-versus-patched test result is included in the commit message.

ANNOUNCE: nbdkit 1.48.0 released

by Richard W.M. Jones

I'm pleased to announce the release of nbdkit 1.48. nbdkit is an NBD server, for Network Block Devices, with a flexible plugin-based architecture and permissive license. Note there are some minor security issues that are fixed in this release. If you're using one of the affected plugins or filters then upgrading is recommended. Thanks Vladimir Vasilev for coordinating these. The release notes are attached below or you can see them online here: https://libguestfs.org/nbdkit-release-notes-1.48.1.html Tarballs are available here: https://download.libguestfs.org/nbdkit/1.48-stable/ Distro updates coming soon. Rich. These are the release notes for nbdkit stable release 1.48. This de‐ scribes the major changes since 1.46. nbdkit 1.48.0 was released on 14 July 2026. Security Fix minor denial of service vulnerability in nbdkit-blocksize-policy-fil‐ ter(1) (Eric Blake). Fix a minor issue with concurrent connections in nbdkit-golang-plugin(3) (AISLE AI security scanner). Fix two minor denial of service vulnerabilities in nbdkit-split-plugin(1) (AISLE AI security scanner). Fix a memory leak and document a potential denial of service vulnerability (although working by design) in nbdkit-cow-filter(1) (AISLE AI security scanner). Fix a memory leak in server option parsing (AISLE AI security scanner). Plugins In nbdkit-file-plugin(1) we no longer advertize minimum_io_size larger than 64K even for backing storage like LVM that could support it. This is because the NBD protocol itself does not support larger sizes (thanks Ni‐ jin Ashok, Eric Blake, Mikulas Patocka). In nbdkit-sparse-random-plugin(1) the block size is now configurable at run time. In nbdkit-vddk-plugin(1) test against VDDK 9.0.1.0. Filters New nbdkit-xor-filter(1) simply XORs a pattern or PRNG with the underlying data, providing simple obfuscation. nbdkit-cow-filter(1) now supports arbitrarily large overlays, even when the filesystem used to store the overlay has file size limitations (eg. 16T on ext4) nbdkit-ip-filter(1) now allows you to filter on loopback addresses. Language bindings In nbdkit-ocaml-plugin(3) a new "NBDKit.Error" exception can be used to throw a precise errno with error message. Also "Unix_error" exception is now translated to errno and error, and there are other improvements to "Failure" and "Invalid_argument" exceptions. In nbdkit-ocaml-plugin provide convenience functions for converting bytes and string types into "NBDKit.buf" Server nbdkit --port=0 can be used to let the kernel pick a free listening port. "LISTEN_FDNAMES" is now parsed for socket activation, although we do noth‐ ing aside from printing socket names. API New nbdkit_debug_hexdiff(3) function which shows the differences between two binary buffers. New nbdkit_name(3) function which returns the nbdkit --name parameter to plugins and filters. New nbdkit_timestamp(3) function which returns a timestamp suitable for log messages. When parsing human sizes (eg. in nbdkit_parse_size(3)), allow hex and oc‐ tal sizes, and allow "_" before the scaling factor. For example "0x1_E" is parsed as 1 exabyte. nbdkit_read_password(3) "password=-" now reads the password from /dev/tty on operating systems that support this. Documentation Document how to disable shadow stack support for loading plugins that were not compiled with this feature. Tests A new interoperability test with Digital Ocean's Go-NBD client library was added. Fix CI (Daniel Berrangé). Build Setting "NBDKIT_VALGRIND_MASSIF=1" will run nbdkit under valgrind massif (for memory profiling). SEE ALSO nbdkit(1). AUTHORS Authors of nbdkit 1.48: Daniel P.
