[Libvirt-announce] Release of libvirt-1.2.6

[Daniel Veillard]

  As planned I have tagged the release in git and pushed the tarball
as well as signed rpms to the usual place:
   ftp://libvirt.org/libvirt/

I also tagged 1.2.6 for the libvirt tree and pushed the associated
release to its own tree:
   ftp://libvirt.org/libvirt/python/
