=head1 RELEASE NOTES FOR LIBGUESTFS 1.46
|
|
|
|
The big news in this release is that the virt tools like
|
|
L<virt-builder(1)>, L<virt-cat(1)>, L<virt-customize(1)>,
|
|
L<virt-df(1)>, and many more were moved to a new project. The
|
|
temporary repository for the new guestfs-tools project is here:
|
|
L<https://github.com/rwmjones/guestfs-tools> while we set up a
|
|
permanent home for it on gitlab. The tarballs containing the tools
|
|
are here: L<https://download.libguestfs.org/guestfs-tools/>
|
|
|
|
Spinning out all of the tools into a new repository has made
|
|
libguestfs a bit easier and simpler to build and manage, and allows us
|
|
to focus on just being the API.
|
|
|
|
Note that the tools L<guestfish(1)> (which is really a "shell API"),
|
|
L<guestmount(1)>, L<libguestfs-test-tool(1)> and L<virt-rescue(1)> are
|
|
still part of the libguestfs repo.
|
|
|
|
The not quite so big news is that we have moved away from FreeNode to
|
|
Libera Chat for IRC. The new channel on Libera is called C<#guestfs>
|
|
(thanks Daniel Berrangé).
|
|
|
|
=head2 Language bindings
|
|
|
|
Libguestfs is now compatible with Go 1.16, and defines a Go module
|
|
(thanks Gianfranco Costamagna).
|
|
|
|
Memory leaks in Python APIs that returned structs are fixed (thanks 朱丹).
|
|
|
|
Python PyPi code has been relicensed to LGPLv2+ (from GPLv2+).
|
|
|
|
=head2 Inspection
|
|
|
|
Inspection of RPM guests now uses librpm instead of trying to parse
|
|
the Berkeley DB directly. Since most RPM-based guests have replaced
|
|
BDB with sqlite this allows us to read these newer guests while
|
|
retaining compatibility with the older guests (thanks Panu Matilainen).
|
|
|
|
Inspection of RHEL 8+ with split /usr configuration has been made more
|
|
reliable.
|
|
|
|
Inspection of Windows Server 2022 should now work correctly (Yongkui
|
|
Guo).
|
|
|
|
=head2 API
|
|
|
|
=head3 New APIs
|
|
|
|
No new APIs were added in libguestfs 1.46.
|
|
|
|
=head3 Other API changes
|
|
|
|
The output of the C<guestfs_cap_get_file> API has changed slightly
|
|
because of changes in the underlying libcap. This isn't strictly
|
|
speaking an API break because the new output is a still valid but more
|
|
compact description of file capabilities, but because it is different
|
|
it may cause problems for users of the API.
|
|
|
|
The C<guestfs_mkfs_btrfs> API now ignores the C<allocstart> parameter
|
|
since it was deprecated by btrfs 4.14.1 and later removed.
|
|
|
|
C<guestfs_isoinfo_*> APIs now directly parse the CD Primary Volume
|
|
Descriptor instead of using an external tool. The APIs should appear
|
|
to work exactly the same (thanks Thomas Schmitt).
|
|
|
|
You can now force the appliance to use KVM or fail if not supported
|
|
(Sam Eiderman).
|
|
|
|
Because of a change to XFS in version 5, disabling lazy-counters no
|
|
longer works. The API still works for earlier versions of XFS (Laszlo
|
|
Ersek).
|
|
|
|
=head2 Build changes
|
|
|
|
The build now uses and requires PCRE2 (instead of PCRE).
|
|
|
|
This version requires libvirt E<ge> 7.1.0, if libvirt is enabled.
|
|
|
|
gnulib is no longer bundled with libguestfs, making builds from git
|
|
much simpler.
|
|
|
|
Perl C<Sys::Virt> (libvirt bindings for Perl) are no longer required
|
|
by libguestfs.
|
|
|
|
The code has been compiled with both LTO and GCC I<-fanalyzer> and
|
|
many bugs and warnings fixed.
|
|
|
|
Allow projects like guestfs-tools and virt-v2v to be compiled with
|
|
locally built (but not installed) libguestfs (Laszlo Ersek).
|
|
|
|
Tests now run in parallel (many additional fixes by Laszlo Ersek).
|
|
|
|
Work around RAID0 regression in Linux 3.14/5.4 (Laszlo Ersek).
|
|
|
|
Support for RISC-V (Heinrich Schuchardt).
|
|
|
|
Support for building on Alma and Cloud Linux (Александр Кравченко).
|
|
|
|
Fix to compile with OCaml 4.12.
|
|
|
|
The tarball no longer includes the F<ChangeLog> file. To get a
|
|
detailed changelog, please look at the upstream git repository.
|
|
|
|
Don't assume bash in the F<./configure> script (Martin Kletzander).
|
|
|
|
Fix F<./configure --with-distro> option (Alexandre Iooss).
|
|
|
|
Various fixes for qemu 6.1.
|
|
|
|
Fix creating appliance dependencies on Debian (Hilko Bengen).
|
|
|
|
Update appliance packages on SUSE and several other improvements to
|
|
the init script (Olaf Hering).
|
|
|
|
=head2 Internals
|
|
|
|
We now use the qemu / libvirt feature I<-cpu max> to select the best
|
|
CPU to run the appliance. This should improve performance for things
|
|
like encrypted disks (Daniel Berrangé).
|
|
|
|
When passing the appliance filesystem UUID to supermin we now read it
|
|
directly out of the appliance instead of using the L<file(1)> program.
|
|
This is more reliable, especially as file often breaks or changed
|
|
its output.
|
|
|
|
The qemu I<-enable-fips> option is no longer used. It was not needed
|
|
and has been deprecated by qemu.
|
|
|
|
On Fedora, pull in glibc-gconv-extra to fix the C<guestfs_syslinux>
|
|
API (Yongkui Guo).
|
|
|
|
We no longer use qemu's sga (Serial Graphics Adapter) option ROM,
|
|
instead using the equivalent seabios feature.
