[Libvirt-announce] ANNOUNCE: Release of libvirt-sandbox version 0.0.2
by Daniel P. Berrange 13 Jan '12

13 Jan '12

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 $ virt-sandbox -c qemu:///session /bin/date Thu Jan 12 22:30:03 GMT 2012 $ virt-sandbox -c qemu:///session /bin/cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 2 model name : QEMU Virtual CPU version 1.0 stepping : 3 cpu MHz : 2793.084 cache size : 4096 KB fpu : yes fpu_exception : yes cpuid level : 4 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm up rep_good nopl pni cx16 hypervisor lahf_lm bogomips : 5586.16 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: $ ./bin/virt-sandbox -c lxc:/// /bin/sh sh-4.2$ ps -axuwf USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 165436 3756 pts/0 Ss+ 22:31 0:00 libvirt-sandbox-init-lxc berrange 24 0.0 0.1 167680 4688 pts/0 S+ 22:31 0:00 libvirt-sandbox-init-common berrange 47 0.0 0.0 13852 1608 pts/1 Ss 22:31 0:00 \_ /bin/sh berrange 48 0.0 0.0 13124 996 pts/1 R+ 22:31 0:00 \_ ps -axuwf Watch this space, there is much more interesting functionality in this space that will be arriving soon...

[Libvirt-announce] ANNOUNCE: libvirt-glib release 0.0.4
by Daniel P. Berrange 13 Jan '12

13 Jan '12

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.

[Libvirt-announce] Start of freeze for libvirt-0.9.9 and availability of rc1
by Daniel Veillard 06 Jan '12

06 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/
