1 Release notes for libguestfs 1.8.0
2 ----------------------------------
4 Updated to commit 573e01e0871324c038bac2fd391c86c8b7fb0247 (1.7.23)
6 These release notes only cover the differences from the previous
7 stable/dev branch split (1.6.0). For detailed changelogs, please see
8 the git repository, or the ChangeLog file distributed in the tarball.
12 - Support and packages for Debian and Ubuntu.
14 - Daily builds from git repository on Debian and Ubuntu to reduce risk
17 - Port to ArchLinux 'pacman' (thanks Thomas S Hatch).
19 - The following tools have been rewritten in C (originally in Perl):
27 - Some C tools support encrypted guests automatically. This is
28 supported in: guestfish, guestmount, virt-cat, virt-inspector,
31 - New tool virt-filesystems (in C) which is a replacement for
32 virt-list-filesystems and virt-list-partitions, and has a superset
33 of the functionality of those tools.
35 - guestfish, guestmount and the C tools use unified command line option
36 parsing, so they support many common options such as '-a disk.img',
37 '-d libvirt-domain', '-x', '-v'. The old command line option
38 parsing is preserved for compatibility in scripts etc.
40 - guestfish no longer has any dependencies on Perl
42 - New man pages containing programming examples: guestfs-examples(3) (C/C++),
43 guestfs-ocaml(3), guestfs-python(3), guestfs-ruby(3).
45 - Trace mode prints return values from API functions.
47 - virt-inspector can list applications installed in Windows guests, along
48 with a great deal of information about those applications.
50 - Add support for inspecting: Linux Mint, Mandriva, FreeBSD.
52 - guestfish --rw option (with no effect currently) to make potentially
53 dangerous write access explicit.
55 - guestfish --listen --csh for compatibility with csh, tcsh (thanks
58 - The first upstream version that introduced each API function is now
59 documented in guestfs(3).
61 - guestfs_last_errno allows you to retrieve the errno from the
62 daemon, correctly translated to the local operating system.
64 - Functions can now have optional parameters.
66 - Progress bars and progress notifications can now happen for upload
69 - Appliance builder more careful about not leaving temporary files
74 - New SECURITY section in guestfs(3) API documentation.
76 - virt-inspector no longer runs any guest commands.
78 - Inspection code is more careful about avoiding very large files
79 from guests which might previously have caused a denial of service.
85 - inspect-get-hostname
86 - inspect-get-package-format
87 - inspect-get-package-management
89 - inspect-list-applications
94 - C programs now only link precisely with the libraries that they use.
96 - PCRE, libmagic, hivex and libvirt libraries are now completely
97 optional for building.
99 - Multiple memory leaks and file descriptor leaks fixed.
101 - Add a POD wrapper to unify generation of man pages and HTML files
104 - Source includes phony images of Fedora, Debian, Ubuntu and
107 - Ruby bindings have 'make install' rule.
109 - <guestfs.h> is now a single file.
111 - <guestfs.h> does not require XDR headers.
113 - ocaml xml-light library is no longer required to build (thanks
116 - ./configure --disable-[...] for each language binding (thanks
119 - Old ocaml-viewer program removed (use guestfs-browser instead).
121 - New C API test type 'InitScratchFS' makes the tests run a little
126 - 657499 checksum: wrong check sum type causes umount to fail
127 - 655554 Whole disk paths are not made canonical by virt-inspector
128 - 654638 openssl updated to 1.0.0b libguestfs depends on exact file names
129 - 652796 ruby bindings not installed by 'make install', hence omitted from the binary distribution
131 Release notes for libguestfs 1.6.0
132 ----------------------------------
134 These release notes only cover the differences from the previous
135 stable/dev branch split (1.4.0). For detailed changelogs, please see
136 the git repository, or the ChangeLog file distributed in the tarball.
140 - Use a new method for creating and caching the appliance. This
141 greatly improves the performance of libguestfs, often by a factor
144 - Support for guest inspection (like virt-inspector) via the ordinary
145 API and all language bindings. 'guestfish -i' option is as a side-
148 - virt-inspector and core inspection API can now detect guests running:
149 Fedora, Debian, Ubuntu, Windows, Red Hat Enterprise Linux, CentOS,
150 Scientific Linux, Gentoo, Pardus, Arch Linux, MeeGo.
152 - Support for LUKS whole-disk encryption in guests.
156 - Progress messages (and progress bars in guestfish and virt-resize)
157 for certain long-running operations.
159 - virt-df is now much more efficient. Use '--one-per-guest' to restore
160 the old per-guest isolation behaviour.
162 - guestfish 'copy-in' and 'copy-out' commands for copying files and
163 directories recursively in and out of the guest.
165 - guestfish 'hexedit' command for doing binary edits to devices and
168 - Change guestfish -i syntax to allow commands to be specified on the
169 command line (retaining backwards compatibility).
171 - guestfish '-d <domain>' for adding disks from libvirt domains.
173 - guestfish '-N' option supports several new prepared disk image types:
174 lvfs : disk with LV formatted with filesystem
177 bootrootlv : boot and root on LV
179 - guestfish 'more' and 'edit' commands now work with arbitrary files.
181 - guestfish '--echo-keys' option allows you to echo keys/passphrases
184 - guestmount now supports -a / -d / -i options, like guestfish.
186 - Use virtio-serial for communications with the appliance. This
187 also has a major performance benefit.
189 - virt-edit '-b' option to create a backup of edited files.
191 - virt-edit '-e' option for non-interactive edits to files.
193 - Ability to capture core dumps from the appliance (thanks Matthew Booth).
195 - virt-rescue now shuts down cleanly (thanks Matthew Booth).
197 - virt-rescue now has a --network option to enable network access.
199 - virt-resize can now handle guests which use GPT partition table format.
201 - virt-resize has better support for shrinking guests.
203 - virt-resize supports qcow2-format guests.
205 - $TMPDIR can be used to override almost all temporary directory usage.
207 - OCaml users can use an alternate OO-style of coding, eg. g#launch ()
209 - The API supports calls which take optional parameters, eg.
210 $g->add_drive_opts ("disk", readonly => 1);
212 - Trace output now escapes and shortens large strings (thanks
215 - Autosync is now on by default, resulting in more reliable behaviour
216 when the handle is closed.
218 - virt-df --uuid option allows you to follow a domain across migration
221 - Translations of manual pages.
225 - CVE-2010-3851 libguestfs: missing disk format specifier when adding a disk
226 https://www.redhat.com/archives/libguestfs/2010-October/msg00036.html
227 This is comprehensively fixed in this release, and the fix will be
228 backported to the other stable branches after more testing.
