[libvirt] ANNOUNCE: libguestfs 1.40 released



I'm pleased to announce libguestfs 1.40, a library and a set of tools
for accessing and modifying virtual machine disk images.

This release represents about a year of work by many contributors.
I'd like to call out in particular substantial contributions from:
Pino Toscano, Tomáš Golembiovský, Nir Soffer and Nikolay Ivanets.
See the release notes below for full details.

Release notes for libguestfs 1.40

These are also available online at:
http://libguestfs.org/guestfs-release-notes.1.html

   New features
     New features in existing tools

       Virt-inspector now displays the libosinfo short ID for guests (Pino
       Toscano).

       Guestfish -N will now generate 1G disks instead of 100M disks by
       default.

       Virt-resize supports f2fs filesystems (Pino Toscano).

       libguestfs-test-tool now supports bash tab completion (Pino Toscano).

       The --machine-readable option now supports sending output to files or
       stdout/stderr.  This works uniformly across most OCaml-based virt
       tools, specifically: virt-builder, virt-builder-repository, virt-dib,
       virt-get-kernel, virt-resize, virt-sparsify, and virt-v2v (Pino
       Toscano).

       Virt-builder --uninstall option now works on SUSE (Sebastian Meyer).

       Virt-builder now supports Windows.  We are not able to ship Windows
       templates in the public respository for obvious licensing reasons, but
       if you are an MSDN subscriber you may build your own.  See
       https://rwmj.wordpress.com/2018/09/13/creating-windows-templates-for-virt-builder/

       Many tools now support a --key option allowing you to pass in
       decryption keys for filesystems stored in local files on the host
       rather than having to feed them in over stdin (Pino Toscano).

     virt-v2v and virt-p2v

       New -o rhv-upload mode for directly uploading images to RHV, bypassing
       the Export Storage Domain (Tomáš Golembiovský, Nir Soffer, Daniel Erez,
       Pino Toscano).

       New -o openstack mode for directly uploading images to OpenStack and
       Cinder using OpenStack APIs.

       Virt-v2v now has a general mechanism for input and output options: -io
       and -oo.

       Virt-v2v can now install the RHV tools or QEMU GA in guests (Tomáš
       Golembiovský).

       The huge manual has now been split into several smaller documents and
       is more focused on helping users to accomplish specific v2v tasks.

       Multiple improvements to the OVF metadata when converting to RHV (Tomáš
       Golembiovský, Pino Toscano, Arik Hadas).

       Virt-v2v can now convert Linux guests with split kernel packages,
       especially Ubuntu 18.04 (Pino Toscano).

       Virt-v2v old --password-file option has been replaced by -ip (the old
       option remains for backwards compatibility).

       Virt-v2v now preserves the VM Generation ID.

       Virt-v2v has a new --mac option allowing specific NICs to be mapped
       precisely to networks or bridges on the target.

       New virt-v2v --print-estimate option to estimate the size of data that
       virt-v2v will copy.

       Virt-v2v is now usually able to remove open-vm-tools and VMware Tools
       from the Linux guest during conversion (Pino Toscano).

       Virt-v2v can now support UEFI conversions to RHV (Tomáš Golembiovský).

       Virt-p2v now prefers you to shut down instead of rebooting the machine
       after conversion has finished (Pino Toscano).

       Virt-v2v now writes the libosinfo short ID to the libvirt metadata when
       using -o local and -o libvirt output modes (Martin Kletzander).

     Language bindings

       OpenJDK 10+ is supported (Pino Toscano).

       Java bindings fixed for Gentoo host (Martin Kletzander).

     Inspection

       Support Kali Linux (Pino Toscano).

       When inspecting mountpoints, look for /etc/mdadm/mdadm.conf as well as
       /etc/mdadm.conf (Nikolay Ivanets).

       Improved support for OpenSUSE Tumbleweed (Pino Toscano).

     Architectures and platforms

       Miscellaneous macOS build fixes (Adam Robinson).

     Other

       Multiple documentation typos fixed (Yuri Chornoivan).

   Security
       See also guestfs-security(1).

       CVE-2018-11806

       Qemu's slirp (userspace networking) had several buffer overflows which
       could be triggered from the guest or network side.

   API
       New APIs

       "f2fs_expand"
           Expand an f2fs filesystem (Pino Toscano).

       "inspect_get_osinfo"
           Get the libosinfo short ID for the inspected guest (Pino Toscano).

       "lvm_scan"
           This rescans all PVs, VGs and LVs, optionally activating them.

       Other API changes

       "part_get_mbr_part_type" was reimplemented in OCaml (Nikolay Ivanets).

       "list_filesystems" now filters out MBR extended partitions (Nikolay
       Ivanets).

       "vgscan" has been deprecated.  Use the new "lvm_scan" API in
       preference.

   Build changes
       The JSON library switched from yajl to Jansson ≥ 2.7 (Pino Toscano).

       Support for The Sleuth Kit 4.5 (Pino Toscano).

       Multiple improvements in the "./configure" script (Lin Ma).

       More out-of-tree build fixes (Hilko Bengen).

       Some work on reproducible builds (Bernhard M. Wiedemann).

   Internals
       lvmetad is now used unconditionally, and is started much earlier in the
       appliance boot process.  This fixes support for certain PV types.

       On Debian, dash is installed inside the appliance and in virt-rescue
       (Pino Toscano).

       The amount of RAM assigned to the appliance has been increased from
       500M to 768M (on x86_64, other architectures have different limits).
       This enables use of up to 255 disks when using recent Linux kernels.

       Virt-v2v now models the source machine type (eg. i440FX, Q35 or virt).

       Virt-p2v now generates configuration code automatically, also code for
       parsing the kernel command line.

       Use "LT_INIT" instead of "AC_PROG_LIBTOOL".

       The OCaml "JSON" code for parsing and serializing has been unified into
       a single abstract data type.

       Most OCaml tools are now built using the PIC runtime.  This has a
       performance penalty on i686, but is relatively free on other
       architectures and has security benefits.

       The direct backend now queries the qemu binary for availability of KVM,
       instead of using a heuristic based on /dev/kvm (Andrea Bolognani).

       Our "clever" libxml2 writer macros are now used consistently across all
       parts of the code base.

       Qemu dropped -nodefconfig without telling us.  The equivalent
       -no-user-config option is now used instead.  Qemu also moved the
       "serial" option from -drive to -device, again without any notice, and
       this is also fixed.
