Inspection¶

Add support for Windows 2025 (thanks Ming Xie).

Add support for TencentOS (Denise Cheng).

Inspection of Ubuntu 22+ guests that use a split /usr configuration now works properly (thanks Jaroslav Spanko, Daniel Berrange).

Inspecting guests that have duplicated root mountpoints now works.

Inspection of SUSE Linux guests using btrfs snapshots now ignores snapshots that mirror content in the root filesystem (thanks Ming Xie).

Inspection of SUSE Linux >= 15 now returns the correct osinfo short name (eg. "sle15") (thanks Ming Xie).

API¶

New "command_out" and "sh_out" APIs which allow you to capture output from guest commands that generate more output than the protocol limit allows.

New "btrfs_scrub_full" API which runs a full Btrfs scrub, synchronously. It works more like fsck for other filesystems.

The "fstrim" API has been modified to work around several issues in upstream and RHEL 9 kernels related to XFS support (Eric Sandeen, Dave Chinner).

The existing "e2fsck" API has a new "FORCENO" option enabling use of the command line -n flag.

Language bindings¶

Previously "-L../lib/.libs" got embedded in the distributed OCaml bindings. This has been fixed.

GObject bindings have been deprecated and will be removed in libguestfs 1.58.

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.

Fix compatibility with file(1) ≥ 5.46.

Fix compatibility with Fedora ≥ 42 which merges /usr/sbin into /usr/bin.

Fix compatibility with latest Rust compiler (Jacob Reger).

lex(1), yacc(1) and libmagic (part of file(1)) have not been required by libguestfs for a long time, but were still checked by the ./configure script. This has been fixed, they are no longer build dependencies (thanks Mohamed Akram).

When using "./configure --disable-daemon" we no longer require augeas and hivex (thanks Mohamed Akram).

"zfs-fuse" support has been dropped. The project is unmaintained upstream (thanks Paul Bolle, Gwyn Ciesla, Timothée Ravier).

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.

Fix dhcpcd failing on systemd-resolved stub (Thomas Wouters).

Add support for dhcpcd and sfdisk on Debian (Daniel Gomez).

Print the kernel utsname in debug output.

The legacy "pvs_full", "vgs_full" and "lvs_full" APIs were completely rewritten in OCaml.

Some deprecated autoconf macros are no longer used.

We no longer emit a false warning about "BLKDISCARD" when creating a block device.

Some internal OCaml List and String functions that we used have been replaced by ones from the OCaml stdlib, reducing code maintenance.

If qemu-img(1) commands fail during snapshot creation, make sure we capture and print stderr from the qemu command (Cole Robinson).
