Hopefully the builds on BSD and Windows should be fixed, it would be good if it could be tested on OsX and since there was a build done last month on Android, I wonder if this could be done again [1]. thanks everybody !

[Libvirt-announce] Start of freeze for libvirt-0.9.8 and availability of rc1
by Daniel Veillard 01 Dec '11

01 Dec '11

We are now entering the freeze for libvirt-0.9.8 . For portability sake I think adding more support for PPC machines should still be allowed for a few days, as long as it's not impacting too much of the common code. I have made a release candidate 1 tarball (and associated rpms) at ftp://libvirt.org/libvirt/libvirt-0.9.8-rc1.tar.gz and the git tree is tagged. I think I will make an rc2 on Mon or Thu and then try to make the release around Thursday next week if things looks good. Please give it a try ! thanks in advance, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[Libvirt-announce] ANNOUNCE: libvirt-glib release 0.0.2
by Daniel P. Berrange 22 Nov '11

22 Nov '11

I am pleased to announce that a new release of the libvirt-glib package, version 0.0.2 is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Add API to redefine an existing domain. - Explicitly call virInitialize() to avoid connection races. - Adjust example to latest pygobject-3.0. - Add missing deps on libxml2-devel & libtool. - Add support for writing to streams - Add API for creating transient domains - Change all flags parameters to be guint - Uncomment & fix code for returning object config - Ensure pools & domains hashes are non-NULL to avoid SEGV - Don't de-reference GError instances which are NULL - Update COPYING file to have latest FSF address - Update RPM specfile to include Fedora review feedback libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable, for the first few releases, we are *NOT* guaranteeing that libvirt-glib libraries are API/ABI stable. ABI stability will only be guaranteed once the bulk of the APIs have been fleshed out and proved in non-trivial application usage. We anticipate this will be within the next 6 months in order to line up with Fedora 17. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.

[Libvirt-announce] ANNOUNCE: libvirt-glib release 0.0.1
by Daniel P. Berrange 16 Nov '11

16 Nov '11

I am pleased to announce the first release of the libvirt-glib package, version 0.0.1 is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key ID: 15104FDF Daniel P. Berrange <berrange(a)redhat.com> Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system As of this release only the event loop integration and some basic APIs for managing domains are provided. The representation of XML as GObjects is a major work item that is just beginning. The libvirt-gconfig library can be used without linking to the main libvirt.so library, so it is suitable for consumption by applications which use libvirt indirectly via AMQP, CIM or another API transport which accepts XML documents. All the libraries support GObject introspection to enable immediate usage from any language which can dynamically import objects via introspection. There are also Vala bindings which are automatically generated from the introspection data. NB: While libvirt aims to be API/ABI stable, for the first few releases, we are *NOT* guaranteeing that libvirt-glib libraries are API/ABI stable. ABI stability will only be guaranteed once the bulk of the APIs have been fleshed out and proved in non-trivial application usage. We anticipate this will be within the next 6 months in order to line up with Fedora 17. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com developmenht list. Thanks to all the people involved in contributing to this release.

[Libvirt-announce] Start of freeze for libvirt-0.9.7 and availability of rc1
by Daniel Veillard 03 Nov '11

03 Nov '11

We are now entering the freeze for libvirt-0.9.7 . We may make an exception for patch set which got a few round of reviews though, like Stefan's ones (v4 IIRC), and anything which we know may need fixing in the API before the release. I have made a release candidate 1 tarball (and associated rpms) at ftp://libvirt.org/libvirt/libvirt-0.9.7-rc1.tar.gz I think I will make an rc2 on Wed or Thu and then try to make the release around Friday of the end of the week if things looks good. Please give it a try ! thanks in advance, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[Libvirt-announce] [libvirt-users] ANNOUNCE: Perl binding release Sys-Virt version 0.9.5
by Daniel P. Berrange 29 Sep '11

29 Sep '11

I am pleased to announce a new release of the Perl binding, Sys::Virt version 0.9.5, is now available for download: http://search.cpan.org/CPAN/authors/id/D/DA/DANBERR/Sys-Virt-0.9.5.tar.gz Changes in this release - Add all new APIs in libvirt 0.9.5 - Add missing snapshot creation/lookup methods - Fix typo in method listing snapshots - Add missing snapshot constant - Add example for save/restore usage - Re-add abort job binding accidentally deleted All historical releases and online documentation are available from the CPAN page http://search.cpan.org/dist/Sys-Virt/ There is no planned update for libvirt 0.9.6, since that did not introduce any new APIs that require work in the Perl layer.

[Libvirt-announce] Release of libvirt-0.9.6
by Daniel Veillard 22 Sep '11

22 Sep '11

That's what is now usually called a brown paper bag release (dixit Linus) [*] since 0.9.5 had broken shudown with the two last released versions of QEmu 0.9.6 should be available at the usual place: ftp://libvirt.org/libvirt/ and obviously only contains a few bug fixes and local improvements. People should not ship 0.9.5, and use 0.9.6 instead, thanks in advance ! Bug Fixes: - snapshot: fix logic bug in qemu undefine (Eric Blake) - sanlock: fix memory leak (Eric Blake) - virsh: fix regression in argv parsing (Eric Blake) - storage: Wait udev events are handled before removing lvm vol (Osier Yang) - qemu: avoid dereferencing a NULL pointer (Alex Jia) - qemu: Avoid loop of fake reboots (Jiri Denemark) - qemu: Fix shutdown regression with buggy qemu (Jiri Denemark) - remote: fix crash on OOM (Eric Blake) Improvements: - snapshot: also delete empty directory (Eric Blake) - snapshot: remove snapshot metadata on transient exit (Eric Blake) - snapshot: prepare to remove transient snapshot metadata (Eric Blake) - virsh: More friendly err if no pool is specified for looking up a vol (Osier Yang) - tests: improve test failure diagnosis (Oskari Saarenmaa) - API: prefer to use NULLSTR macro (Osier Yang) - xen: use typical allocations (Eric Blake) - virsh: Remove useless codes of cmdVolPath (Osier Yang) Portability: - build: silence warning on 32-bit build (Eric Blake) Thanks to all who reported and helped fix those issues quickly !!! Daniel [*] and no I won't carry one, they are non-existent where I live for context http://lwn.net/1999/0204/kernel.php3 -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

Yeah Eric pointed that out, I already commited his patch and the associated make syntax-check test :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
