NAME guestfs-release-notes - libguestfs Release Notes RELEASE NOTES FOR LIBGUESTFS 1.28 These release notes only cover the differences from the previous stable/dev branch split (1.26.0). For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball. 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=). This enables full-featured network connections, with working ICMP, ping and so on.

stable/dev branch split (1.24.0). For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball. New features Tools virt-customize(1) is a new tool for customizing virtual machine disk images. It lets you install packages, edit configuration files, run scripts, set passwords and so on. virt-builder(1) and virt-sysprep(1) use virt-customize, and command line options across all these tools are now identical. virt-diff(1) is a new tool for showing the differences between the filesystems of two virtual machines. It is mainly useful when showing what files have been changed between snapshots. virt-builder(1) has been greatly enhanced. There are many more ways to customize the virtual machine. It can pull templates from multiple repositories. A parallelized internal xzcat implementation speeds up template decompression. Virt-builder uses an optimizing planner to choose the fastest way to build the VM. It is now easier to use virt-builder from other programs. Internationalization support has been added to metadata. More efficient SELinux relabelling of files. Can build guests for multiple architectures. Error messages have been improved. (Pino Toscano) virt-sparsify(1) has a new --in-place option. This sparsifies an image in place (without copying it) and is also much faster. (Lots of help provided by Paolo Bonzini) virt-sysprep(1) can delete and scrub files under user control. You can lock user accounts or set random passwords on accounts. Can remove more log files. Can unsubscribe a guest from Red Hat Subscription Manager. New flexible way to enable and disable operations. (Wanlong Gao, Pino Toscano) virt-win-reg(1) allows you to use URIs to specify remote disk images. virt-format(1) can now pass the extra space that it recovers back to the host. guestfish(1) has additional environment variables to give fine control over the > prompt. Guestfish reads its (rarely used) configuration file in a different order now so that local settings override global settings. (Pino Toscano) virt-make-fs(1) was rewritten in C, but is unchanged in terms of functionality and command line usage. Language bindings The OCaml bindings have a new Guestfs.Errno module, used to check the error number returned by Guestfs.last_errno. PHP tests now work. (Pino Toscano) Inspection Inspection can recognize Debian live images. Architectures ARMv7 (32 bit) now supports KVM acceleration. Aarch64 (ARM 64 bit) is supported, but the appliance part does not work yet. PPC64 support has been fixed and enhanced. Security Denial of service when inspecting disk images with corrupt btrfs volumes It was possible to crash libguestfs (and programs that use libguestfs as a library) by presenting a disk image containing a corrupt btrfs volume. This was caused by a NULL pointer dereference causing a denial of service, and is not thought to be exploitable any further. See commit d70ceb4cbea165c960710576efac5a5716055486 for the fix. This fix is included in libguestfs stable branches ≥ 1.26.0, ≥ 1.24.6 and ≥ 1.22.8, and also in RHEL ≥ 7.0. Earlier versions of libguestfs are not vulnerable. Better generation of random root passwords and random seeds When generating random root passwords and random seeds, two bugs were fixed which are possibly security related. Firstly we no longer read excessive bytes from /dev/urandom (most of which were just thrown away). Secondly we changed the code to avoid modulo bias. These issues were not thought to be exploitable. (Both changes suggested by Edwin Török) API GUID parameters are now validated when they are passed to API calls, whereas previously you could have passed any string. (Pino Toscano) New APIs guestfs_add_drive_opts: new discard parameter The new discard parameter allows fine-grained control over discard/trim support for a particular disk. This allows the host file to become more sparse (or thin-provisioned) when you delete files or issue the guestfs_fstrim API call. guestfs_add_domain: new parameters: cachemode, discard These parameters are passed through when adding the domain's disks. guestfs_blkdiscard Discard all blocks on a guestfs device. Combined with the discard parameter above, this makes the host file sparse. guestfs_blkdiscardzeroes Test if discarded blocks read back as zeroes. guestfs_compare_* guestfs_copy_* For each struct returned through the API, libguestfs now generates guestfs_compare_* and guestfs_copy_* functions to allow you to compare and copy structs. guestfs_copy_attributes Copy attributes (like permissions, xattrs, ownership) from one file to another. (Pino Toscano) guestfs_disk_create A flexible API for creating empty disk images from scratch. This avoids the need to call out to external programs like qemu-img(1). guestfs_get_backend_settings guestfs_set_backend_settings Per-backend settings (can also be set via the environment variable LIBGUESTFS_BACKEND_SETTINGS). The main use for this is forcing TCG mode in the qemu-based backends, for example: export LIBGUESTFS_BACKEND=direct export LIBGUESTFS_BACKEND_SETTINGS=force_tcg guestfs_part_get_name Get the label or name of a partition (for GPT disk images). Build changes The following extra packages are required to build libguestfs 1.26: supermin ≥ 5 Supermin version 5 is required to build this version of libguestfs. flex, bison Virt-builder now uses a real parser to parse its metadata file, so these tools are required. xz This is now a required build dependency, where previously it was (in theory) optional. Internals PO message extraction rewritten to be more robust. (Pino Toscano) podwrapper gives an error if the --insert or --verbatim argument pattern is not found. Libguestfs now passes the qemu -enable-fips option to enable FIPS, if qemu supports it. ./configure --without-qemu can be used if you don't want to specify a default hypervisor. Copy-on-write [COW] overlays, used for example for read-only drives, are now created through an internal backend API (.create_cow_overlay). Libvirt backend uses some funky C macros to generate XML. These are simpler and safer. The ChangeLog file format has changed. It is now just the same as git log, instead of using a custom format. Appliance start-up has changed: * The libguestfs appliance now initializes LVM the same way as it is done on physical machines. * The libguestfs appliance does not write an empty string to /proc/sys/kernel/hotplug when starting up. Note that you must configure your kernel to have CONFIG_UEVENT_HELPER_PATH="" otherwise you will get strange LVM errors (this applies as much to any Linux machine, not just libguestfs). (Peter Rajnoha) Libguestfs can now be built on arches that have ocamlc(1) but not ocamlopt(1). (Hilko Bengen, Olaf Hering) You cannot use ./configure --disable-daemon --enable-appliance. It made no sense anyway. Now it is expressly forbidden by the configure script. The packagelist file uses m4 for macro expansion instead of cpp. Bugs fixed https://bugzilla.redhat.com/1073906 java bindings inspect_list_applications2 throws java.lang.ArrayIndexOutOfBoundsException: https://bugzilla.redhat.com/1063374 [RFE] enable subscription manager clean or unregister operation to sysprep https://bugzilla.redhat.com/1060404 virt-resize does not preserve GPT partition names https://bugzilla.redhat.com/1057504 mount-local should give a clearer error if root is not mounted https://bugzilla.redhat.com/1056290 virt-sparsify overwrites block devices if used as output files https://bugzilla.redhat.com/1055452 libguestfs: error: invalid backend: appliance https://bugzilla.redhat.com/1054761 guestfs_pvs prints "unknown device" if a physical volume is missing https://bugzilla.redhat.com/1053847 Recommended default clock/timer settings https://bugzilla.redhat.com/1046509 ruby-libguestfs throws "expecting 0 or 1 arguments" on Guestfs::Guestfs.new https://bugzilla.redhat.com/1045450 Cannot inspect cirros 0.3.1 disk image fully https://bugzilla.redhat.com/1045033 LIBVIRT_DEFAULT_URI=qemu:///system breaks libguestfs https://bugzilla.redhat.com/1044585 virt-builder network (eg. --install) doesn't work if resolv.conf sets nameserver 127.0.0.1 https://bugzilla.redhat.com/1044014 When SSSD is installed, libvirt configuration requires authentication, but not clear to user https://bugzilla.redhat.com/1039995 virt-make-fs fails making fat/vfat whole disk: Device partition expected, not making filesystem on entire device '/dev/sda' (use -I to override) https://bugzilla.redhat.com/1039540 virt-sysprep to delete more logfiles https://bugzilla.redhat.com/1033207 RFE: libguestfs inspection does not recognize Free4NAS live CD https://bugzilla.redhat.com/1028660 RFE: virt-sysprep/virt-builder should have an option to lock a user account https://bugzilla.redhat.com/1026688 libguestfs fails examining libvirt guest with ceph drives: rbd: image name must begin with a '/' https://bugzilla.redhat.com/1022431 virt-builder fails if $HOME/.cache doesn't exist https://bugzilla.redhat.com/1022184 libguestfs: do not use versioned jar file https://bugzilla.redhat.com/1020806 All libguestfs LVM operations fail on Debian/Ubuntu https://bugzilla.redhat.com/1008417 Need update helpout of part-set-gpt-type https://bugzilla.redhat.com/953907 virt-sysprep does not correctly set the hostname on Debian/Ubuntu https://bugzilla.redhat.com/923355 guestfish prints literal "\n" in error messages https://bugzilla.redhat.com/660687 guestmount: "touch" command fails: touch: setting times of `timestamp': Invalid argument https://bugzilla.redhat.com/593511 [RFE] function to get partition name https://bugzilla.redhat.com/563450 list-devices returns devices of different types out of order RELEASE NOTES FOR LIBGUESTFS 1.24 These release notes only cover the differences from the previous stable/dev branch split (1.22.0). For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball. New features User-Mode Linux (UML) can be used as an alternative backend (ie. instead of KVM). This improves performance especially when using libguestfs inside a VM (eg. in the cloud). UML is supported as a first-class backend. See "USER-MODE LINUX BACKEND" in guestfs(3) for how to use this. ARM (32 bit) and PPC64 are now fully supported. Tools virt-builder(1) is a new tool for building virtual machine images. It lets you rapidly and securely create guests and customize them. New virt-sysprep(1) operations: Remove files in /tmp and /var/tmp. Remove RPM database files. Change root and user passwords. More log files are removed. New operations which are not enabled by default: Create random UUIDs for filesystems. Reset firewall rules. (Wanlong Gao) virt-resize(1) and virt-sysprep can now use URIs to specify a remote disk. Use guestfish -N filename=type to create a named disk image (instead of the default test1.img etc). virt-sparsify(1) now tests if there is enough disk space to complete the operation, instead of possibly running out of space half way through. virt-format(1) and virt-make-fs(1): new --label option for setting filesystem label. virt-resize --no-sparse flag can be used to resize on to partitions and other targets that are not zeroed. Language bindings New bindings for the Go programming language. API Support for the systemd journal. guestfs_add_drive_opts can now control the qemu caching mode through a new cachemode parameter. You can select improved performance for temporary drives, or safety. guestfs_set_label now works for XFS and btrfs. New GUESTFS_EVENT_WARNING event for warning messages. Inspection Better inspection of SUSE guests (Olaf Hering). Better support for non-standard Windows %systemroot% (Matthew Booth). Enhanced error reporting for Augeas errors. Security CVE-2013-2124 https://bugzilla.redhat.com/show_bug.cgi?id=968306 A denial of service was possible when inspecting certain guests. The fix has been backported to 1.20 and 1.22 branches. CVE-2013-4419 https://www.redhat.com/archives/libguestfs/2013-October/msg00031.html Fix insecure temporary directory handling for remote guestfish. The fix has been backported to 1.20 and 1.22 branches. New APIs add-drive-scratch: Add a temporary scratch drive aug-label aug-setm journal-open: Systemd journal support journal-close journal-next journal-skip journal-get journal-get-data-threshold journal-set-data-threshold remount: Allow rw flag to be adjusted on mounted filesystems set-uuid: Set UUID of filesystem is-file, is-dir, is-blockdev, is-chardev, is-fifo, is-socket APIs now have an extra followsymlinks flag. add-drive has a new cachemode parameter. Build changes The following packages are required to build libguestfs 1.24: Augeas ≥ 1.0.0 The following optional packages may be added to enhance functionality but are not required: sd-journal To read journal files from guests which use that. url_mkcow For UML backend. curl gpg xz For virt-builder. golang ≥ 1.1.1 For Go language bindings. Internals New make check-* rules replace make extra-tests. See make help and guestfs(3) for details. Perl code can now be valgrinded. Inspection code is now fuzz-tested. make no longer recurses into the generator directory in every other directory. This reduces the overhead of builds considerably. Additional tests for Augeas, hivex. Add a launch timeout of 20 minutes waiting for the appliance to start up. Add a timeout (4 hours) to all tests so we can catch the case where qemu or other components hang. Use kvmclock and -cpu host. This improves clock stability and overall performance. ./configure --enable-packet-dump mode is fixed. ./configure --enable-valgrind-daemon mode has been rewritten. It is now feasible for developers to keep this flag enabled at all times. Backends have been refactored to be modular (although they are not actually loadable modules). When enabled, the network now uses resolver configuration (ie. /etc/resolv.conf) from the host.

For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball. New features API Remote access to disks: * Network Block Device (nbd) * Secure Shell (ssh) * HTTP and HTTPS * FTP and FTPS * iSCSI * Gluster * Ceph/rbd (Mike Kelly) * Sheepdog * TFTP The SYSLINUX and EXTLINUX bootloaders can now be installed in disk images using the API. Inspection can now handle filesystems such as btrfs where subvolumes are separately mountable (Matthew Booth). "Attach methods" are now known as "backends". Compatibility with existing code is preserved. Filenames can contain ':', as long as newer QEMU is being used. Tools Virt-alignment-scan and virt-df scan multiple guests in parallel. Guestmount now passes errno accurately back to userspace in almost all cases. Guestfish and other tools can now use a URI-like syntax to access remote disks, eg: guestfish -a ssh://example.com/path/to/disk.img Guestfish and guestmount now allow you to specify the filesystem type when mounting, which is more secure (Dave Vasilevsky). Guestfish is now the "guest filesystem shell". Guestfish allows only 1 true t yes y on 0 false f no n off for boolean values (case insensitive), and gives an error for all other strings. New tool guestunmount for unmounting FUSE filesystems safely. guestmount --no-fork flag prevents guestmount from daemonizing. Virt-resize now uses sparse copies by default, saving considerable space for guests which are mostly empty. Bash tab completion has been rewritten and can now handle most tools, and correctly tab-complete --long options. In addition, bash completion scripts are loaded on demand. Language bindings The Java API now supports events. The Python object now inherits from the object base class. Python methods which previously returned lists of tuples can now be made to return a Python dict. For backwards compatibility, you have to enable this by using the constructor option guestfs.GuestFS (python_return_dict=True). The PHP bindings are now tested properly, and have had multiple fixes. The long-deprecated Perl Sys::Guestfs::Lib library has been removed. https://www.redhat.com/archives/libguestfs/2013-April/msg00001.html Examples New example program showing how to enable debugging and capture log messages. Other Distributors can add arbitrary extra packages to the appliance by doing: ./configure --with-extra-packages="list of package names" Distributors can use: ./configure --with-supermin-extra-options="..." to add arbitrary extra options to supermin. Security No security issues were found in this release. New APIs cp-r extlinux feature-available get-program is-whole-device part-get-gpt-type part-set-gpt-type rename set-program syslinux C only: guestfs_event_to_string Internals The febootstrap tool has now been renamed to "supermin". Libguestfs can use either, but now prefers "supermin". http://people.redhat.com/~rjones/supermin/ libxml2 is required to build libguestfs. The hivexregedit program (from hivex) is required to build from git. Internal functions can no longer be used unless the caller defines -DGUESTFS_PRIVATE=1. Enable C compiler warnings in Python, Ruby bindings. Fail early and clearly if libvirt does not support qemu/KVM (eg. if default libvirt connection is to Xen). make print-subdirs rule, useful for selectively running tests. Multiple fixes to allow separated (sourcedir != builddir) builds. Multiple fixes to Haskell bindings. ln and ln-f APIs now capture errno correctly. Language binding tests use (mostly) a standard numbering scheme and aim to test the same range of features in each language. Also the number of launches required has been reduced so these tests should run much more quickly. Library code internally uses GCC __attribute__((cleanup)) (if available) to simplify memory allocation. Internal header files have been reorganized. See the comments in src/guestfs-internal*.h Internal code shared between the library and certain tools is now located in a static libutils library. Almost all subdirectories can now use parallel builds, although note that the top-level directories still build in series. Use of PATH_MAX and NAME_MAX has been eliminated from the code. The Java API now requires JVM ≥ 1.6. Force use of serial-tests with automake ≥ 1.12. Use of sockets in the library protocol layer is abstracted, allowing other non-POSIX layers to be added in future (see src/conn-socket.c). qemu-img info --output json is used if available, for more secure parsing of the output of this command. Distros can now use make INSTALLDIRS=vendor install to place Ruby bindings in vendordir. This eliminates a non-upstream patch carried by both Fedora and Debian. Valgrind log files are now written to tmp/valgrind-DATE-PID.log make clean cleans the local tmp/ directory. The C API tests have been rewritten using a more flexible generator language that allows arbitrary C code to be executing during tests.

For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball. New features libvirt and sVirt (SELinux confinement) You can optionally use libvirt to launch and manage the backend appliance by: * setting LIBGUESTFS_ATTACH_METHOD=libvirt[:URI] * using ./configure --with-default-attach-method=libvirt[:URI] * or calling the API method guestfs_set_attach_method SVirt (SELinux confinement) is used to secure the libguestfs appliance, if the libvirt backend is selected. virtio-scsi, larger number of drives, hotplugging Virtio-scsi is now used by default, if it is available. This greatly increases the number of drives that can be added to a single libguestfs handle (up to 255). You can now hotplug drives (add and remove drives after launch). Libguestfs can now handle > 25 disks, in all APIs, tools and tests. You can label drives when adding them, then refer to them by label (/dev/disk/guestfs/LABEL) instead of having to use device names (/dev/sda). new library features POSIX Access Control Lists (ACLs) and Linux filesystem capabilities can now be read and written through the API. Windows Dynamic Disks are now supported. The metadata can only be read (volumes cannot be modified or created). However the data/filesystems in the volumes themselves can be mounted, read and written (Matthew Booth). Hivex (Windows Registry editing) is now directly supported through the API, making reading or editing the Windows Registry much more efficient. Several libguestfs APIs were reimplemented so they no longer have any limits on output. The reimplemented APIs are: guestfs_cat, guestfs_find, guestfs_read_file, guestfs_read_lines, guestfs_write, guestfs_write_append, guestfs_lstatlist, guestfs_lxattrlist, guestfs_readlinklist, guestfs_ls. virt tools guestfish touch 'win:c:\new_file' now works as expected. guestfish has a new --network option, which enables the user network in libguestfs. You can set GUESTFISH_PS1 to use fancy prompts in guestfish. rsync, ssh, less and lrzip commands are now available in virt-rescue. In addition, rsync can be used through the API for doing incremental copies. virt-sparsify uses qcow2 v3 for increased efficiency. virt-sysprep enhancements: * generate new UUIDs for PVs and VGs * remove the local machine ID (Wanlong Gao) * remove ABRT data (Wanlong Gao) * remove puppet keys and log files (Wanlong Gao) * remove process accounting files (Wanlong Gao) * new --firstboot parameter allowing firstboot scripts for customizing guests * remove HOSTNAME field from ifcfg-eth* files (Wanlong Gao) * miscellaneous improvements for SuSE (Olaf Hering) * remove man pages cache (Wanlong Gao) * remove crash data generated by kexec-tools (Wanlong Gao) virt-make-fs can now create virtual floppy disks (VFDs). guestmount has a --pid-file option, which can be used to avoid a race condition between unmounting the filesystem and using the underlying disk image. language bindings Full-featured Lua bindings have been added in this release (thanks to Jerome Vuarand for many suggestions). In Ruby, optional arguments hash is optional. In Python, optional arguments now don't use special "sentinel" values, so any integer can be passed as an optional argument. Erlang bindings now come with examples and tests. Erlang bindings now handle 64 bit integer parameters correctly. The automated 'bindtests' now test for 64 bit cleanliness in parameter passing. Several bugs in the bindings were found and fixed as a result. Better handling of blocking and non-blocking functions should make libguestfs calls more efficient. inspection Windows guests with unlimited-sized Registries are now supported. By adding the hivex API to the libguestfs API, it is much more efficient and easier to inspect and modify the Windows Registry in guests. Better support for SuSE guests (Olaf Hering). Return the architecture of installed applications (John Eckersberg). Windows 8 is now supported. Fedora 18 is now supported. Inspection of ISOs/CDs/DVDs can now use the libosinfo database. ports Libguestfs without the appliance can be compiled on Mac OS X (Masami HIRATA). RHEL 5 is now explicitly supported through the 'oldlinux' branch in upstream git. PowerPC 64 bit is now supported. Also libguestfs has been examined for endianness bugs and these have been fixed. daemon A man page for the daemon (guestfsd(8)) is included. Security guestfish history file The $HOME/.guestfish history file is now created with 0600 permissions (instead of 0644 before) so it is no longer world readable. CVE-2012-2690 Old versions of both virt-edit and the guestfish edit command created a new file containing the changes but did not set the permissions, etc of the new file to match the old one. The result of this was that if you edited a security sensitive file such as /etc/shadow then it would be left world-readable after the edit. This issue was assigned CVE-2012-2690, and is fixed in libguestfs ≥ 1.16.

Coverity has been run over the complete codebase, and many issues fixed (thanks Ondrej Vasik, Kamil Dudka). Functions which previously had no optargs can now be converted to ones with optargs, making extending the API much more flexible. Source and binary backwards compatibility is preserved for users of the API. The way that libguestfs APIs and structures are represented in the generator has changed to use an OCaml struct instead of a tuple. This makes generator descriptions more flexible and easier to understand. For details see commits 39d1a7db and eb185eef. Separation of the library code into more files: * Launch backends are now located in separate files eg. src/launch-appliance.c, src/launch-libvirt.c. * Generated action code is now split over several src/action*.c files, for faster compilation. * The huge src/guestfs.c file is now split into smaller logical units. POD (documentation) is now generated using a rewritten Perl program instead of pod2* + shell scripts. Man pages now contain stable dates (Hilko Bengen). Skipped tests now exit with code 77, so they appear as SKIP: in make check output. The parallel mount-local test has been rewritten in C (RHBZ#838081). Ruby 1.8.5 is now supported (though Ruby ≥ 1.9 is preferred). Perl bindings can be disabled via ./configure --disable-perl (Wulf C. Krueger). Note that Perl is still required in order to build libguestfs. Java bindings are now enabled/disabled using ./configure --with-java or ./configure --without-java (Wulf C. Krueger). New configure options ./configure --enable-code-profiling and ./configure --enable-code-coverage. Multiple fixes to use of 64 bit integers in language bindings. The appliance backend now uses sgabios instead of vgabios (Dan Berrange). The ./run script now sets enough environment variables that you can run OCaml, Python, Ruby, Java, GJS, Erlang, Lua programs. ./run --test flag for running tests with minimal output. It also prints the time taken to run each test. The ./run script now builds up paths cumulatively, meaning that you can use ./run twice, or use the libguestfs and libvirt ./run scripts together. You can extract a list of external commands required by the daemon, making building the appliance on certain distros easier (Olaf Hering). The virt-rescue command is now tested during make check. The generator now removes unused generated files. This helps when going back and forth with git rebase, git bisect, etc. Tests now run in a separate toplevel tmp/ directory in the source. This allows the directory to be labelled for SELinux (sVirt), and also makes it easier to clean up. make syntax-check now works to a greater extent, and many problems in the main code that were found by syntax-check have been fixed (thanks Jim Meyering). Emacs mode (-*- foo -*-) has been added to generated files. Progress bar output is now sent to /dev/tty so it doesn't end up in the regular output of the program. virt-resize and virt-sparsify now suppress progress bars if stdout is not a tty. There is now a ./configure --without-libvirt option. This is useful for testing that the code still compiles without libvirt. There is now an internal mini-library for running commands. This allows us to redirect errors from external commands into events. Code for handling temporary directories and the appliance cache was completely overhauled. Code for temporarily ignoring/disabling errors now looks like this: guestfs_push_error_handler (g, NULL, NULL); guestfs_mkdir (g, "/foo"); /* We don't care if this fails. */ guestfs_pop_error_handler (g); The tests/extra directory has gone. The "extra tests" are now split into separately runnable targets, such as make check-valgrind. Use make help to get a summary of the targets. The lpj option is passed to the appliance kernel when using TCG. This should improve clock stability (thanks Marcelo Tosatti, Olaf Hering).

New features - guestfish lets you choose a prepared disk image, eg: guestfish -N fs:ext4 - Add write support to guestmount (FUSE) module. - virt-resize can now resize the content of partitions and logical volumes in the guest, and we have better support for shrinking guests. - Bash tab-completion script for guestfish. - Add ZFS support to virt-rescue. - New tool 'virt-make-fs' for creating filesystems with content. - Allow suffixes on any guestfish number parameter, eg. "1M". - guestfish 'man' command opens the manual page. - guestfish supports a "heredoc" syntax for uploading files: upload -<<_end_ /foo content _end_ - Some guestfish commands now print their output in octal or hex where appropriate (RHBZ#583242). - Allow dash prefix on guestfish command line.
