guestfs-release-notes-1.601

Inspection

Add support for Kylin, NeoKylin and Anolis Linux distributions (grass lu).

Guests using Veritas partition tables (reusing the Sun partition type) can now be inspected.

Windows Defender (antivirus) is now detected if present in Windows guests (Susant Sahani).

API

New "guestfs_xfs_info2" API. This is similar to the existing "guestfs_xfs_info" API but returns a flexible hashtable allowing more fields to be added to the output in future.

"guestfs_get_hv" now returns the default hypervisor.

"guestfs_tar_in" adds a new option "keepdirlink" which controls the tar --keep-directory-symlink flag (Anders Roxell).

"guestfs_xfs_repair" "maxmem" option now produces better error messages if maxmem is too small.

All functions that take LUKS key parameters may now use either "text:..." or "base64:..." prefixes, allowing binary keys to be encoded as base64 and passed to these APIs. guestfish(1) and other tools taking a key file now allow a binary file to be used.

"guestfs_command*" and "guestfs_sh*" now use a bind mount to override "/etc/resolv.conf" inside the guest, allowing these commands to work even when this file is marked as immutable, a common change that system administrators make (Srihari Parimi).

Tools

New guestfish(1) "not" subcommand, which negates the status of a command.

Language bindings

GObject and Vala bindings were removed. They were previously deprecated in libguestfs 1.56 (Cole Robinson).

Documentation

All information related to firstboot scripts was moved to and consolidated in "FIRSTBOOT" in virt-customize(1) (Srihari Parimi).

Fix documentation of "guestfs_copy_out" API.

Build changes

Fix Weblate (i18n) web hooks (Rafael Fontenelle).

Fix build when libselinux is not available (David Runge).

Github CI is now used more comprehensively (Cole Robinson).

Fix "make dist" command when certain language bindings are disabled (Cole Robinson).

"./configure --with-qemu" was removed.

"CFLAGS" is now prepended to the default, allowing default flags to be overridden. In addition -fPIC is added to the default flags (Cole Robinson).

Some bash completion scripts that were no longer used by libguestfs (they moved to guestfs-tools) were removed. Also new "./configure --with-bash-completion" and "./configure --with-bash-completion-dir" options were added (Christopher Byrne).

No longer over-link Lua bindings with libxml2 and libvirt (David Runge).

Improve appliance support for Arch (David Runge).

Internals

Simplify qemu property testing. Most of the code was eliminated completely, and also we no longer start up an empty guest when detecting if KVM is available (thanks Daniel Berrange). Also we now print stderr if qemu fails to start during detection (Hilko Bengen).

Use -cpu max on RISC-V (thanks Apache553).

Very minimal support for Apple Filesystem (APFS) was added on Fedora.

Many memory and file descriptor leaks found by Claude Code were fixed (shivanayak).

In the libguestfs appliance, increase the number of pre-process memory maps. This may allow xfs_repair to work on larger filesystems (Eric Sandeen).

Fix DHCP on fast machines by making it wait for an address when networking is enabled. In addition use "dhcpcd --debug" which makes it easier to see if DHCP requests are working (Cole Robinson).

Improvements to debug output (Surya Gupta, Srihari Parimi).

Fix Fedora bin/sbin symlinking to be less noisy (Cole Robinson).

Rewrite xfs_repair and luks_* implementations in the daemon in OCaml.

Ensure fds 0, 1 and 2 are open when running subcommands.
