set of tools for accessing and modifying virtual machine disk images.

Release notes (http://libguestfs.org/guestfs-release-notes-1.42.1.html)

       Please note that virt-v2v, virt-p2v and the boot analysis tools were
       moved out of the libguestfs package / repository into separate
       projects.  See:

       ·   https://github.com/libguestfs/virt-v2v

       ·   https://github.com/libguestfs/virt-p2v

       ·   https://github.com/libguestfs/libguestfs-analysis-tools

       Those projects are now on a separate release cycle.  Release notes are
       published separately.

   New features
       Add support for the Vala language (Corentin Noël).

       Add support for the Rust language (Hiroyuki Katsura, sponsored by
       Google Summer of Code).

       Reproducible builds (Chris Lamb).

       Advanced Format disks (which use 4K sectors) can now be processed by
       libguestfs.  Use the new optional "blocksize" parameter to
       "guestfs_add_drive_opts", and the --blocksize option added to
several
       tools (Nikolay Ivanets).

       Windows CompactOS (NTFS file compression) is now supported.

       New features in existing tools

       Advanced machine readable output in various virt tools now supports
       JSON output, and writing logs to a numbered file descriptor (Pino
       Toscano).

       virt-filesystems tool now more accurately reports filesystem total
       size, in the case where for example the filesystem does not occupy the
       whole of its containing device (Pino Toscano).

       Language bindings

       Python ≥ 2.7 is required.

       Python bindings are now more extensively tested (Hiroyuki Katsura).

       Python bindings should now work with Python ≥ 3.8.

       Multiple fixes to avoid crashes in the Python bindings (Sam Eiderman).

       OCaml bindings are compiled with "-DCAML_NAME_SPACE" to ensure
no
       non-caml_-namespaced symbols are used (Pino Toscano).

       OCaml bindings should now work with OCaml 4.09 and 4.10.

       Erlang has deprecated the old "erl_interface" library which we
use for
       Erlang bindings.  It will be removed in OTP 22, which will permanently
       break Erlang support unless someone steps forward to update the Erlang
       bindings in libguestfs.

       Fix compatibility with newer cgo for Go bindings (Tomáš Golembiovský).

       Go API error handling is now more idiomatic (Csaba Henk).

       Update documentation about how to handle boolean parameters in Ruby
       bindings (Csaba Henk).

       Inspection

       Libguestfs can now extract icons for Gentoo, newer SUSE and
       OpenMandriva guests.  Improved extraction of RHEL icons.  (Pino
       Toscano).

       Inspection returns the osinfo IDs of newer Windows versions, and
       rolling Linux distros (Pino Toscano).

       OpenMandriva is now detected (Bernhard Rosenkränzer).

       Arch Linux detection improvements (Pino Toscano).

       Architectures and platforms

       Libguestfs can now be compiled on OpenMandriva (Bernhard Rosenkränzer).

       Ubuntu fix for enabling network support (Ioanna Alifieraki).

       Other

       Use of deprecated libguestfs APIs will now cause compiler deprecation
       warnings by default, whereas previously you have to enable these
       warnings.  To turn off these warnings use
       "-DGUESTFS_NO_WARN_DEPRECATED=1".  A new feature is that you
can now
       disable deprecated APIs completely if you want, using
       "-DGUESTFS_NO_DEPRECATED=1" (Pino Toscano).

       Fix hostname in virt-builder templates (Pino Toscano).

       The single large release notes file is now split into multiple
       documents organized by version.

       The "--key" option of several tools was broken, especially if
you tried
       to use the option to pass multiple keys.  This has been fixed and a
       regression test added.

       Augeas exceptions occurring in daemon (eg. during inspection) will now
       produced detailed errors (Pino Toscano).

   Security
       No security issues were found in this release.

   API
       New APIs

       "luks_uuid" returns the UUID of a LUKS device (Pino Toscano).

       Other API changes

       Cope with new output from the "btrfs scrub" command.  There is
no
       visible change at the API level.

       New optional parameter "blocksize" added to
"guestfs_add_drive_opts" to
       support Advanced Format disks (Nikolay Ivanets).

   Build changes
       Minimum version of Augeas required is 1.2.0 (Pino Toscano).

       "common/" subdirectory is now a git submodule shared with the
virt-v2v
       project.

       Supermin ≥ 5.1.18 is required.

       There were several bugs in libvirt 5.10.0 and 6.0 which affected
       libguestfs.  It is highly advisable to use libvirt 6.1 where these bugs
       are fixed (versions of libvirt < 5.10.0 are also fine).

       Many gnulib modules which we were not using or which we used in only a
       few places have been removed (Pino Toscano).

       Multiple fixes for builddir != sourcedir builds (Pino Toscano).

       A new "bundled/" subdirectory contains one bundled library that
we
       currently use, "ocaml-augeas" (Pino Toscano).

       Fix compatibility issues when being compiled with GCC 10.

   Internals
       When linking OCaml programs, automake silent rules and the
"V=1" flag
       are both now obeyed (Pino Toscano).

       The "guestfs_device_index" API was reimplemented in library
code
       instead of in the daemon.  There should be no observable effect of this
       change.

       Since Linux 5.6 enumerates "/dev/sdX" devices in parallel,
libguestfs
       was changed to map API device names to appliance device names, and then
       do the reverse mapping when returning names from the appliance.
       Hopefully this should have no observable effect, but can produce
       somewhat confusing debugging messages since device names in the debug
       might not match device names passed in to APIs.  Furthermore the
       "root=UUID=..." option is always passed to the appliance
(instead of
       naming the device containing the root filesystem).

       We expect to move from the Zanata service to the Weblate service for
       translated strings.  For more information see

software inside the virtual machine.  Supports Linux and Windows.

Hi,

will a stable-1.42 branch be created from the v1.42.0 tag?
(not advocating either choice, just asking)

Thanks,

Yes, sorry I forgot, will do it now.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
