I'm pleased to announce the releases of libguestfs 1.50 and guestfs-tools 1.50. These are a library and a set of tools for for accessing and modifying filesystems inside virtual machines and disk images, securely and without needing root access.
You can download both projects here: https://download.libguestfs.org/1.50-stable/ https://download.libguestfs.org/guestfs-tools/1.50-stable/ I've attached the release notes below, or you can read them online here: https://libguestfs.org/guestfs-release-notes-1.50.1.html https://libguestfs.org/guestfs-tools-release-notes-1.50.1.html Thanks to the many authors who have contributed to these releases. Rich. - - - RELEASE NOTES FOR LIBGUESTFS 1.50 These are the release notes for libguestfs stable release 1.50. This describes the major changes since 1.48. Libguestfs 1.50.0 was released on 7 February 2023. Language bindings Fix the PHP bindings for PHP8 (Geoff Amey). Fix various deprecation warnings in the GObject bindings. We no longer use the deprecated Python distutils library (thanks Miro Hrončok). Inspection When listing the packages in RPM-based guests, the inspection API no longer checks package signatures. This is because the newer librpm used by libguestfs does not understand signatures stored in older guests, such as SHA1 used by RHEL 6 (thanks Panu Matilainen). "guestfs_inspect_get_hostname" in guestfs(3) can now handle /etc/hostname files containing comments (thanks Dawid Zamirski). "guestfs_file_architecture" in guestfs(3) can now parse files using zstd compression. "guestfs_inspect_get_osinfo" in guestfs(3) now returns the correct osinfo field for Windows 11. However because of decisions made by Microsoft, these guests still return product name and other strings identifying as Windows 10 (thanks Yaakov Selkowitz, Yongkui Guo). API New APIs "guestfs_device_name" in guestfs(3) is a new API to read the device name associated with a drive, for example calling this with 0 will return "/dev/sda". "guestfs_clevis_luks_unlock" in guestfs(3) is a new API for unlocking disks using the Clevis/Tang network-based full disk encryption scheme. Furthermore implement this in guestfish and guestmount (Laszlo Ersek). "guestfs_inspect_get_build_id" in guestfs(3) is a new API for reading the build ID from some Linux and Windows guests. It is not widely used on Linux, but for Windows it is vital for identifying Windows 11. Other API changes In the "guestfs_add_drive" in guestfs(3) API, the "name" and "iface" fields are not used. "name" has not been used since around 2017, but the documentation has only just been updated to reflect this. "iface" was never allowed for the libvirt backend and didn't work reliably with the direct backend (Laszlo Ersek). "guestfs_readdir" in guestfs(3) is no longer limited to the maximum message size but can read a directory of any size (Laszlo Ersek). Build changes Note that the Augeas bindings for libguestfs are no longer bundled with libguestfs and must be built separately. See: https://people.redhat.com/~rjones/augeas/ For RHEL 7+ rebuilding the Fedora Rawhide package will work. Note that libguestfs now requires minimum OCaml 4.04. It will not compile on RHEL 6. Note that zstd is now a required dependency. OCaml gettext is no longer a dependency of libguestfs. (Plain gettext is still optionally used to translate C source files.) Add support for OCaml 4.14. Fix build for missing stdlib functions in OCaml 4.04. Fix "./configure --disable-ocaml". OCaml is still required to build libguestfs, but this now correctly disables the OCaml bindings of the API. Add support for building on Artix, Rocky and Virtuozzo (Halil Tezcan KARABULUT, Neil Hanlon, Andrey Drobyshev). In addition when working out the local distro we now look at $ID_LIKE in /etc/os-release before $ID which helps on Arch (thanks S D Rausty). Add preliminary support for compiling libguestfs on macOS. Fix website description of cloning the libguestfs repository (Kashyap Chamarthy). We no longer use glibc custom printf. We no longer use "LD_PRELOAD=libSegFault.so" in the appliance. This feature was removed in glibc 2.35. We no longer use dtrace / systemtap probes. Internals Fix regression tests to use correct paths (Nikolay Shirokovskiy). Various improvements to qcow2 appliance handling (Andrey Drobyshev). Disable 5-level page tables in qemu. This avoids a bug in older versions of qemu. Disable the LVM2 devicesfile in the appliance since it interferes with cloned LVs that have the same UUID (Laszlo Ersek). Don't use "-cpu max" on RISC-V as it is not yet supported by qemu's TCG emulation of that architecture. This will be reenabled when qemu gets support. Avoid a rare hang that would happen when launching the appliance. This turned out to be caused by using the unsafe call setenv(3) between fork and exec (thanks Siddhesh Poyarekar). When running the file command inside the appliance we now disable seccomp since it interferes with processing compressed files (thanks David Runge, Toolybird).

This describes the major changes since 1.48. Guestfs tools 1.50.0 was released on 7 February 2023. Security CVE-2022-2211 https://bugzilla.redhat.com/show_bug.cgi?id=2100862 A buffer overflow was found in the --key option of several guestfs tools. For more information on this low severity bug see the bug report above (Laszlo Ersek). New virt-drivers tool This new tool can examine a disk image to determine: • Whether it uses BIOS or UEFI for booting • What bootloader it uses (Linux only) • What kernels may be chosen at boot time (Linux only) • What device drivers (kernel modules) are installed This is useful for determining how (or if) a guest can boot on a virtualization hypervisor. virt-customize --selinux-relabel is now the default for SELinux guests. You no longer need to specify this flag. In the rare case where you don't want to relabel a guest after customizing it, you can use --no-selinux-relabel. Note this is not needed for non-SELinux guests, it will do the right thing automatically (Laszlo Ersek). New --inject-qemu-ga and --inject-virtio-win operations which respectively inject QEMU Guest Agent and virtio-win drivers into Windows guests. Rocky Linux guests are now supported (thanks Harry Benson). virt-inspector Virt-inspector now outputs the new <build_id> element containing the guest build ID, if using libguestfs ≥ 1.50. virt-sysprep New "lvm-system-devices" operation for removing LVM2's system.devices file. This avoids certain problems when cloning a VM (Laszlo Ersek). Virt-sysprep supports guests using LUKS logical volumes on top of LVM (Laszlo Ersek). Common changes All the tools supporting the --key option can now use Clevis/Tang to decrypt full disk encryption using this network-based scheme (Laszlo Ersek). Build changes Note that libguestfs now requires minimum OCaml 4.04. It will not compile on RHEL 6. Note that libosinfo is a new required dependency. OCaml 4.14 is now supported. "./configure --disable-ocaml" and "./configure --disable-perl" now disable the OCaml- and Perl-based tools respectively (thanks Simon Walter). Experimental support for compiling on macOS. When running "make check-valgrind", Valgrind logs are no longer written to separate files under tmp/. Instead the output is written to the normal test-name.log file.
