[Libvirt-announce] ANNOUNCE: Release of libvirt-sandbox version 0.0.2
by Daniel P. Berrange
I pleased to announce the first public release of libvirt-sandbox,
version 0.0.2 is now available for download
ftp://libvirt.org/libvirt/sandbox/
The packages are GPG signed with
Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R)
The libvirt-sandbox package provides an API layer on top of libvirt-gobject
which facilitates the cration of application sandboxes using virtualization
technology. An application sandbox is a virtual machine or container that
runs a single application binary, directly from the host OS filesystem.
In other words there is no separate guest operating system install to build
or manager.
At this point in time libvirt-sandbox can create sandboxes using either LXC
or KVM, and should in theory be extendable to any libvirt driver. The first
release is able to run simple command line based programs. While there is
some GUI support, this is mostly unreliable / non-functional at this point
in time, future releases will address this properly.
Some examples

[Libvirt-announce] ANNOUNCE: libvirt-glib release 0.0.4
by Daniel P. Berrange
I am pleased to announce that a new release of the libvirt-glib package,
version 0.0.4 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 support for configuring sound, serial, parallel
and channel devices
- Add support for newer libvirt shutdown event
- Add support for setting SPICE/VNC passwords
- Fix storage pool annotations
- Improve docs for memory APIs
- Fix problem with duplicated attributes
- Many internal XML helper API cleanups/additions
- Add API for retrieving list of all devices
- Fix mixup between g_new0/g_slice_free
- Change namespace for GVirConfig APIs (breaks ABI
and API)
- New APIs for save/suspend
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 redhat com development list.
Thanks to all the people involved in contributing to this release.
Daniel
