guestfs-release-notes - libguestfs Release Notes
RELEASE NOTES FOR LIBGUESTFS 1.26
These release notes only cover the differences from the previous
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 ><fs> 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.

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.

RELEASE NOTES FOR LIBGUESTFS 1.22
These release notes only cover the differences from the previous
stable/dev branch split (1.20.0). 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.

RELEASE NOTES FOR LIBGUESTFS 1.20
These release notes only cover the differences from the previous
stable/dev branch split (1.18.0). 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.

Internals
qemu ≥ 1.1 is required (≥ 1.2 preferred).
febootstrap ≥ 3.20 is required.
libvirt is optional, but if you want to use the new libvirt backend for
launching the appliance then libvirt ≥ 0.10.2 would be required.
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).

RELEASE NOTES FOR LIBGUESTFS 1.14
These release notes only cover the differences from the previous
stable/dev branch split (1.12.0). For detailed changelogs, please see
the git repository, or the ChangeLog file distributed in the tarball.
New features
Erlang bindings.
virt-alignment-scan is a new tool to check the alignment of
partitions within virtual machines or disk images.
virt-sparsify is a new tool to make virtual machine disk images
sparse.
virt-sysprep is a new tool to make cloning guests from a template
simpler.
guestfish
- New commands setenv, unsetenv, to set environment variables.
- The input file and line number is printed in error messages.
- guestfish progress bars are now a "mini-library" used by other
tools too.
guestmount
- the --live option (for access to live VMs) now works.
virt-cat
- virt-cat can now handle Windows paths and drive letters (RHBZ#693359).
virt-filesystems
