[Libguestfs] ANNOUNCE: libguestfs 1.28 released



I'm pleased to announce libguestfs 1.28, a library and set of tools
for accessing and modifying virtual machine disk images.

This release took 7 months of work by a considerable number of people,
and has many new features (see release notes below), including new
'virt-v2v' and 'virt-p2v' tools for importing guests from foreign
hypervisors to KVM, and 'virt-log' which is a tool for extracting log
files from guests (including Windows).

You can get libguestfs 1.28 here:

RELEASE NOTES FOR LIBGUESTFS 1.28

 New features

  Tools

    virt-v2v(1) and virt-p2v(1) are tools for converting from foreign
    hypervisors (such as VMware or Xen) or physical machines, to KVM. These
    tools were previously a separate project. The code for both tools has
    been integrated into the libguestfs tree. As part of the refactoring,
    virt-p2v has been rewritten (from Ruby, now C), and virt-v2v now uses
    several modern features of qemu which make it run many times faster
    than before. virt-v2v(1) can import from: VMware vCenter, VMware OVA
    files, local disk files, libvirt, RHEL 5 Xen. It can output to: oVirt
    or Red Hat Enterprise Virtualization (RHEV-M), OpenStack Glance,
    libvirt, qemu, local disk files.

    virt-log(1) is a new tool for listing log files from guests. It
    supports a variety of guests including Linux traditional, Linux using
    journal, and Windows event log.

    virt-builder(1) has a new --machine-readable option to make it simpler
    to consume virt-builder from other programs.

    New virt-builder(1) and virt-customize(1) --chmod option.

    virt-sysprep(1) will now remove: systemd journals, anaconda logs,
    lightdm logs, debian-installer files, apt logs, exim logs, ConsoleKit
    logs, firewalld logs, grubby logs, proftpd logs, libvirt/libxml logs,
    and several other log files. The virt-sysprep user-account operation is
    now able to remove or keep particular user accounts. (Pino Toscano).

    New guestmount(1) --fd option, allowing you to run guestmount captive
    under another process.

    virt-sparsify(1) has a new --tmp option allowing you to precisely
    control where temporary files are stored.

    virt-sparsify(1) can now write to a block device.

    virt-customize(1) and virt-sysprep(1) now support adding firstboot
    scripts to Windows guests.

    virt-cat(1), virt-edit(1), virt-ls(1) now support the -m option,
    allowing you to override automatic inspection of guests and instead
    specify where to mount partitions (Pino Toscano).

    The virt tools now have coloured output: green for OK, red for errors,
    blue for warnings.

  Language bindings

    You can build a Python distribution using make -C python sdist

    Ruby bindings have switched from Test::Unit to MiniTest.

    The Java bindings are now compatible with OpenJDK 8 (Pino Toscano).

  Inspection

    Oracle Linux is returned as oraclelinux (Nikos Skalkotos).

    Linux guests which do not have /etc/fstab can now be handled (Pino
    Toscano).

    Minix is returned as minix (Pino Toscano).

  Architectures

    Aarch64 (64 bit ARM) support has been added.

    Inspection and the guestfs_file_architecture call can now recognize arm
    (32 bit) and aarch64 guests.

 Security

    CVE-2014-0191 Network usage and entity resolution in XML parsing

      Libguestfs previously used unsafe libxml2 APIs for parsing libvirt
      XML. These APIs defaulted to allowing network connections to be made
      when certain XML documents were presented. Using a malformed XML
      document it was also possible to exhaust all CPU, memory or file
      descriptors on the machine.

      Since the libvirt XML comes from a trusted source (the libvirt
      daemon) it is not thought that this could have been exploitable.

      This was fixed in libguestfs ≥ 1.27.9 and the fix was backported to
      stable versions ≥ 1.26.2, ≥ 1.24.9, ≥ 1.22.10 and ≥ 1.20.13. (Thanks:
      Dan Berrange, Pino Toscano).

    Shellshock (bash CVE-2014-6271)

      This bash bug indirectly affects libguestfs. For more information
      see:
      https://www.redhat.com/archives/libguestfs/2014-September/msg00252.html

 API

  New APIs

    guestfs_clear_backend_setting

    guestfs_get_backend_setting

    guestfs_set_backend_setting

      Use these APIs to set individual backend settings.

    guestfs_cpio_out

      Convert a directory within the disk image to cpio format.

    guestfs_journal_get_realtime_usec

      Fetch precise journal times, see sd_journal_get_realtime_usec(3).

    guestfs_lstatns

    guestfs_lstatnslist

    guestfs_statns

      Enhanced versions of guestfs_lstat, guestfs_lstatlist, guestfs_stat
      which return nanosecond timestamps.

 Build changes

    Libguestfs can now be built with qemu 2.x.

    Add support for packaging the appliance on Mageia (Joseph Wang, Thierry
    Vignaud).

    Augeas is now a required dependency.

    Flex and bison are now required dependencies.

 Internals

    User-Mode Linux (UML) is no longer a supported backend (although still
    available). It will be supported again once someone steps in and fixes
    various regressions and brokenness in the UML (Linux) kernel.

    You can now connect gdb to qemu by specifying
    LIBGUESTFS_BACKEND_SETTINGS=gdb

    Serial BIOS (sgabios) is now used by the libvirt backend (on x86 only)
    so that we see early BIOS messages.

    For the OCaml virt tools, exceptions are now handled and printed by a
    common function.

    A GCC warning about large stack frames is now enabled by default.
    Several places that used large arrays and structures on the stack have
    been fixed.

    There is now a test for booting the appliance repeatedly. Useful for
    finding kernel leaks. See: tests/qemu/qemu-boot.c

    There is a test for testing the speed of various qemu features such as
    virtio-serial uploads and block device writes. See:
    tests/qemu/qemu-speed-test.c

    GCC warnings are now enabled for OCaml-C bindings in the OCaml virt
    tools.

    The code for editing files used by virt-edit(1), guestfish(1) edit
    command, virt-customize(1) --edit option and more is now shared between
    all these utilities (thanks Pino Toscano).

    The FUSE tests were rewritten in C to ensure finer control over how
    system calls are tested.

    The update-bugs.sh script has been fixed so it should no longer create
    an empty BUGS file if the Bugzilla server is unavailable.

    The virt-resize(1) tests now use a stochastic method to ensure much
    deeper and broader testing.

    When the network is enabled, the appliance now uses DHCP to acquire an
    IP address.

    If libvirt is being used then the appliance will connect to virbr0 (can
    be overridden by setting
    LIBGUESTFS_BACKEND_SETTINGS=network_bridge=<some_bridge>). This enables
    full-featured network connections, with working ICMP, ping and so on.
