Release Notes for Guestfs Tools 1.52

These are the release notes for guestfs tools stable release 1.52. This describes the major changes since 1.50.

Guestfs tools 1.52.0 was released on 5 January 2024.

virt-dib was removed

virt-dib, a tool that built disk images using diskimage-builder descriptions has been removed.  It only supported an older version of the diskimage-builder metadata.  See also: https://bugzilla.redhat.com/1910039


virt-builder(1) now prints better error messages when a specific URL cannot be downloaded.


Fix GPG repository signing (thanks Allard Berends).


New virt-customize(1) --chown and --tar-in options.  (Also available in virt-builder and virt-sysprep.)


virt-diff(1) no longer considers st_dev and st_ino fields, which means that guests where a file has moved across a mountpoint but is otherwise identical (size, path, etc) will not show up as a difference.


virt-drivers(1) a tool which looks at the device drivers needed by a guest, can now look up vendor and device names using the PCI and USB IDs databases.

Common changes

The common --key option now recognizes LVM names like /dev/mapper/rhel_bootp--73--75--123-root (Laszlo Ersek).

The --key option also supports a new --key all:... selector to try the same key on all devices.

Build changes

Support for OCaml 5, and OCaml ≥ 4.07 is now the minimum (thanks Guillaume Munch-Maccagnoni, Jerry James, Josh Berdine, Jürgen Hötzel, Vincent Laviron).

Fix compatibility issues with libxml2 2.12.


Fix an off-by-one error which caused very rare crashes in some of the virt tools.

Bugs fixed


virt-v2v failed to inspect RHEL9.2 guest due to kernel-core / kernel-modules-core subpackage split


RFE: Virt-v2v should recognize partition names like '/dev/mapper/rhel boot--73--75--123-root' in related keys option


virt-dib doesn't work with newer diskimage-builder version on RHEL8
