James Fehlig 278a149fdc Accepting request 253577 from home:jfehlig:branches:Virtualization
Note:  tarball verification is now done using %gpg_verify, along
with the .asc file the upstream libvirt maintainer now generates
for each release.  This approach requires using the upstream .gz
tarball, which is slightly larger than the regenerated .bz2 one.

- Update to libvirt 1.2.9
  - Introduce virNodeAllocPages
  - event: introduce new event for tunable values
  - Add support for fetching statistics of completed jobs
  - CVE-2014-3657: domain_conf: fix domain deadlock
  - CVE-2014-3633: qemu: blkiotune: Use correct definition when
    looking up disk
  - Many incremental improvements and bug fixes, see
    http://libvirt.org/news.html
  - Drop upstream patches: 3e745e8f-CVE-2014-3633.patch,
    libvirt-guests-wait-for-ntp.patch
- Verify tarball with associated .asc file
  Add: libvirt.keyring, libvirt-1.2.9.tar.gz.asc
  Use upstream .gz tarball instead of locally generated .bz2
