💅 NAME 💅

okay so this is the guestfs-tools-release-notes page — the guestfs tools release notes, bestie. It lives under Virtualization Support and honestly it's giving "changelog but make it fashion."

✨ RELEASE NOTES FOR GUESTFS TOOLS 1.54 ✨

these are the release notes for guestfs tools stable release 1.54, and they describe the major changes since 1.52. no cap.

guestfs tools 1.54.0 was released on 21st May 2025. mark your calendars, it was a moment.

🦋 New repository location 🦋

the upstream git repository is now:

https://github.com/libguestfs/guestfs-tools

slay. new home, same energy.

🎀 virt-customize 🎀

  • new --inject-blnsvr — this one can be used to inject the Windows memory balloon server into guests. iconic behavior honestly.
  • --inject-virtio-win no longer supports the "osinfo" method (use libosinfo for virtio-win driver information), because it is no longer maintained and had got quite out of date. the default method using virtio-win directory names is more reliable and preferred in all instances (Cole Robinson). periodt — use the default, it ate.

🔥 virt-drivers 🔥

  • handle large output of the rpm(1) command when listing drivers in some SUSE guests. big output? handled. 💅

🌸 virt-make-fs 🌸

  • use the file(1) -S option to disable seccomp protection when we also use the file(1) -z option, as the two options are incompatible and cause crashes on some Linux distros. so yeah — incompatible, crashes, not a vibe. noted.

⭐ virt-resize ⭐

  • correct the calculation of the target disk. in some cases with the --resize option it was not calculated correctly and partition creation on the target would fail with a confusing error. we fixed the math, bestie.
  • we now use stderr consistently for debug messages. consistency is main character energy.

🌈 Common changes 🌈

  • add support for LoongArch (liuxiang from Loongson). new architecture just dropped.
  • fix OCaml bytecode builds (Jerry James, Ilya Leoshkevich).
  • allow "nbd+unix://" URIs in -a parameters to several tools.
  • add a git-publish profile (Kashyap Chamarthy).

🧚 Build changes 🧚

  • json-c is now required. this replaces Jansson which was previously used for parsing JSON input files.
  • OCaml ≥ 4.08 is now required.
  • OCaml oUnit is no longer used.
  • we now assume that "__attribute__((cleanup))" always works. this requires gcc or Clang.
  • add support for GCC 14 and 15.
  • some deprecated autoconf macros are no longer used.
  • fix some issues when building on macOS (Mohamed Akram).
  • fix compatibility with GNU gettext 0.25.

🫶 Internals 🫶

  • the tests were modified to use a set of common functions and remove use of the weird $TEST_FUNCTIONS macro, similar to how we do it in nbdkit. cleaner, cuter, less cursed.
  • some internal OCaml List and String functions that we used have been replaced by ones from the OCaml stdlib, reducing code maintenance. we love a little decluttering moment.
