Release Notes for Libguestfs 1.54

These are the release notes for libguestfs stable release 1.54. This describes the major changes since 1.52.

Libguestfs 1.54.0 was released on 8 October 2024.

Inspection

Add detection of Circle Linux (Bella Zhang).

Add support for LoongArch (liuxiang).

Add detection of Kylin (grass-lu).

Add detection of openEuler (Wang Guoquan).

PARTUUID and PARTLABEL are now resolved in guest /etc/fstab.

API

New APIs findfs_partuuid and findfs_partlabel.  These can be used to efficiently look up a filesystem by its GPT partition UUID or label.

Support for the following inactive or infrequently used device types has been removed: Gluster, Sheepdog, TFTP.

Add GOST R34.11-94 message digest algorithm to checksum APIs (Alexey Shabalin).

Allow nbd+unix:// URIs (NBD over Unix domain socket) in guestfish and other places.

Various part_* (partition) APIs related to GPT have been reimplemented to use util-linux sfdisk instead of sgdisk.  Util-linux is more widely available, so this reduces dependencies in the common case.  One optional API remains that still uses sgdisk.  (Thanks Yongkui Guo).

Add cipher suboption to cryptsetup_open (Jonatan Pålsson).

Because of a bug, the part_get_gpt_attributes API could truncate the return value from 64 to 32 bits.  This has been fixed.

Build changes

Fix btrfs compatibility with kernel changes in Linux 6.7.

Removed some compatibility code for versions of util-linux (sfdisk) prior to 2014.

Pass CFLAGS through when building the Perl bindings.  In particular this means that -g should be passed through correctly, enabling debugging symbols.

Fix build on macOS (Antonio Caggiano).

Internals

Libguestfs will now no longer recommend using LIBGUESTFS_BACKEND=direct.  This was shown previously when libvirt failed to start the appliance.  However it is felt that this now does more harm than good.

Fix generation of virt-customize --chown parameter (Yongkui Guo).

In the appliance, reduce boot time when dhcp isn't needed (Olaf Hering).

A deadlock in the appliance caused by a regression in Linux 6.11 has been worked around.  The deadlock was also fixed in Linux 6.12.
