6 guestfs-release-notes - libguestfs Release Notes
7
9 These release notes only cover the differences from the previous
10 stable/dev branch split (1.8.0). For detailed changelogs, please see
11 the git repository, or the ChangeLog file distributed in the tarball.
12
13 New features
14 - libguestfs and tools can be used against live virtual machines.
15 See the 'guestfish --live' and 'guestmount --live' options, and (for
16 the low-level interface) the new APIs set-attach-method and
17 get-attach-method.
18
19 - New virt tools:
20 virt-copy-in, virt-copy-out, virt-tar-in, virt-tar-out.
21
22 - libguestfs can get the drive letter mappings for Windows guests.
23
24 - virt-inspector displays drive letter mappings for Windows guests.
25
26 - Drive letters can now be used in virt-edit and guestfish programs
27 when operating on Windows guests.
28
29 - virt-resize now works on 32 bit hosts.
30
31 - You can now inspect the install disks and live CDs of many different
32 operating systems.
33
34 - guestfish <! cmd which executes a shell cmd and inlines the result.
35
36 - guestfish, guestmount, virt-rescue now all support --ro and --rw
37 options, and the default for this can be chosen via a configuration
38 file (/etc/libguestfs-tools.conf).
39
40 - New event API allows more than one callback to be registered for
41 each event, makes it possible to call the API from other languages,
42 and allows nearly all log, debug and trace messages to be rerouted
43 from stderr.
44
45 - Greater FHS compliance for temporary files, including using /var/tmp
46 for large cached files that should survive reboot (instead of /tmp).
47
48 - guestfish, guestmount -m option allows mount options to be passed
49 through to the underlying filesystem.
50
51 - mkfs-opts allows filesystem features to be specified.
52
53 - More intelligent handling of mountpoints, allowing mkmountpoint, mount
54 and umount-all commands to work together properly.
55
56 - Trace messages are prefixed with a distinct string, allowing them to
57 be easily 'grepped' out from debug output.
58
59 - guestfs_launch (guestfish 'run' command) now produces progress
60 messages (a guestfish progress bar) if it takes longer than 5
61 seconds to run.
62
63 - Several long-running commands where we are unable to estimate time
64 to completion generate "pulse mode" progress events. Progress bar
65 in guestfish has been updated to display these.
66
67 - Publish new example code in: C, Perl, Python, OCaml, Ruby.
68
69 - New virt-dhcp-address example program.
70
71 - The Java and Ruby bindings have been improved greatly.
72
73 - Perl includes a way to get the errno of the last error.
74
75 - Python bindings now compatible with rpyc (thanks Erez Shinan).
76
77 - Transifex is now being used to manage translations.
78 http://www.transifex.net/projects/p/libguestfs/
79
80 - Inspection now supports Red Hat Desktop, Slackware distributions.
81
82 - Inspection no longer fails for Windows guests that have two or
83 more disks.
84
85 - Inspection can now tell the difference between Windows 2008 Server
86 and Windows 7.
87
88 - Inspection can detect 32 bit applications installed in 64 bit
89 Windows, running on the WOW64 emulator.
90
91 - A series of protocol fixes has fixed the old bug RHBZ#576879
92 which used to cause errors during the upload command to lose
93 protocol synchronization.
94
95 - New logo!
96
97 Security
98 [none]
99
100 New APIs
101 first-private, get-attach-method, inspect-get-drive-mappings,
102 inspect-get-product-variant,
103 inspect-get-windows-current-control-set, next-private, resize2fs-M,
104 set-attach-method.
105
106 Internals
107 - The 'HACKING' file is obsolete. The contents have been moved into
108 a section of the guestfs(3) manual page.
109
110 - libguestfs-test-tool simplified. It no longer needs the static
111 binary or tries to construct an ISO.
112
113 - rpcgen-generated files are compiled with -fno-strict-aliasing
114 which should be safer (thanks Matt Booth).
115
116 - virt-resize was rewritten in OCaml.
117
118 - guestfish and other tools tested with valgrind; some memory leaks
119 were fixed.
120
