libguestfs Release Notes

Release Notes for Libguestfs 1.44

Language bindings

Python 2 support has been dropped.  The minimum version of Python required is 3.6.

Python bindings no longer use deprecated PyEval_ThreadsInitialized.

Python bindings now include type hints (Sam Eiderman).

Erlang bindings now use libei instead of liberl_interface (Sergei Golovan).


virt-get-kernel(1) can now find uncompressed kernels (Pino Toscano).

virt-sysprep(1) now regenerates the guest certificate store when a certificate is removed from the guest (Pino Toscano).

virt-sysprep(1) can now remove IPA enrollment files and Kerberos keytabs (Pino Toscano, Christian Heimes and François Cami).


New APIs

cryptsetup-open and cryptsetup-close replace luks-open, luks-open-ro and luks-close.  The new APIs add support for BitLocker encryption.

Other API changes

lvm-canonical-lv no longer produces a noisy error message when called with a non-LV parameter.

Build changes

C programs using libguestfs can now be compiled against the build directory:

 ../libguestfs/run ./configure
 ../libguestfs/run make

OCaml components are now linked correctly when building in a different directory from the source (Geoff Toole).

GCC LTO is now supported.

Weblate is now used for localization instead of Zanata (Pino Toscano).

The dependencies for guestfsd are no longer hard-coded but are now generated from the built binary, ensuring that they shouldn't get out of synch in future (Hilko Bengen).


lib/guestfs.h was moved to include/guestfs.h in the source. This is not an externally visible change but affected a lot of places inside the build system.

Bugs fixed


The virt-diff command doesn't work on windows 2019 image


The tar-in command does not allow restoring file capabilities
