guestfs-release-notes - libguestfs Release Notes
These are the release notes for libguestfs stable release 1.60. This describes the major changes since 1.58.
Libguestfs 1.60.0 was released on 9 July 2026.
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).
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).
New guestfish(1) not subcommand, which negates the status of a command.
GObject and Vala bindings were removed. They were previously deprecated in libguestfs 1.56 (Cole Robinson).
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.
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).
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.
RFE: Detect Windows Defender antivirus when enabled in default Windows 11 installs
Add new xfs_info2 API to expose XFS version information
virt-v2v with sun partition table and Veritas storage failed with: parted exited with status 1: Warning: The disk CHS geometry reported by the operating system does not match the geometry stored on the disk label
Stop using xfs_repair -m because memory required scales with filesystem size and has sharp edges
virt-v2v failing with binary LUKS keys [virt-v2v]
virt-v2v failing with binary LUKS keys [libguestfs]
virt-v2v failing with binary LUKS keys [guestfs-tools]
virt-v2v fails during migration of RHEL 7 VMs due to XFS filesystem errors, potentially related to RHEL 10.1 xfs_repair running against a RHEL 7 XFS filesystem.
Use bind mount to overwrite /sysroot/etc/resolv.conf during "sh" operations
1.58.0: undefined reference to optgroup_selinuxrelabel_available
guestfs_int_get_cpu_model: use -cpu max for riscv
switch to po4a
flaky test network/test-network.sh
1.58.1: The Lua bindings link against libxml2 but don't seem to use it
