## 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

[**virt-builder**(1)](/virt-builder/1.md) now prints better error messages when a specific URL cannot be downloaded.

### virt-builder-repository

Fix GPG repository signing (thanks Allard Berends).

### virt-customize

New [**virt-customize**(1)](/virt-customize/1.md) *--chown* and *--tar-in* options.  (Also available in virt-builder and virt-sysprep.)

### virt-diff

[**virt-diff**(1)](/virt-diff/1.md) 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

[**virt-drivers**(1)](/virt-drivers/1.md) 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.

### Internals

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

### Bugs fixed

- https://bugzilla.redhat.com/2175703

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

- https://bugzilla.redhat.com/2168506

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

- https://bugzilla.redhat.com/1910039

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