[Libvirt-announce] Start of freeze for libvirt-0.9.9 and availability of rc1
by Daniel Veillard 05 Jan '12

05 Jan '12

We are now entering the freeze for libvirt-0.9.9 . We hadn't yet reviewed Taku Izumi second version of his patchset maybe we can pull his next version in rc2. I have made a release candidate 1 tarball (and associated rpms) at ftp://libvirt.org/libvirt/libvirt-0.9.9-rc1.tar.gz and the git tree is tagged. Note that this will fail to puild outside of PC and PPC arches, but the fix is in git now. I think I will make an rc2 on Tues or Wed and then try to make the release around Friday 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 0.0.3
by Daniel P. Berrange 19 Dec '11

19 Dec '11

I am pleased to announce that a new release of the libvirt-glib package, version 0.0.3 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: - Flesh out API in libvirt-gconfig to allow basic domain configuration - Don't memset private data fields, since glib already ensures this - Fix VPATH builds - Add syntax-check rules ensuring coding style compliance - Describe coding style in HACKING file - Expand libvirt-gobject API to allow watches on streams - Simplify debug system with new glib - Fix libvirt-gobject pkg-config file - Fix domain event handlig wrt transient guests - Don't crash if given a NULL uri to connect to - Expand libvirt-gobject API for storage pools & volumes - Fix some crashes in error paths where GError instance was NULL - Add vala files to the RPM - Add binding for open domain consoles & graphics 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.

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/
