This bug was fixed in the package libvirt - 0.9.8-2ubuntu17.2
---------------
libvirt (0.9.8-2ubuntu17.2) precise-proposed; urgency=low
* debian/libvirt-bin.install, debian/rules: name the apport file
source_libvirt.py, not source_libvirt-bin.py. (LP: #1007405)
* install /etc/dnsmasq.d/libvirt to configure system wide dnsmasq to not
listen on the libvirt bridge. (Following Stéphane's lxc example)
(LP: #928524) (LP: #231060)
- postinst: restart dnsmasq; postrm: remove dnsmasq.d/libvirt file and
restart dnsmasq; rules, libvirt-bin.dirs and libvirt-bin.install:
install new debian/libvirt-bin.dnsmasq file.
* Warn user about bad pc-0.12 machine type, and help user transition.
(LP: #1001625)
- qemu-warn-on-pc-0.12.patch: When defining or starting a VM which uses the
pc-0.12 machine type, warn in libvirtd.log.
- debian/libvirt-migrate-qemu-machinetype: automatically migrate QEMU VMs
to newest machine type. This is not done automatically as there will
be some users who have good reason to stay with pc-0.12.

Bug description:
============ SRU justification ===========
Impact: lxc (by way of lxc-net) fails to start when dnsmasq is installed
Development fix: install a dnsmasq.d file to prevent the system-wide dnsmasq
from binding to lxcbr0
Stable fix: same as Development fix
Test case:
sudo apt-get purge lxc
sudo apt-get -y install dnsmasq
sudo apt-get -y install lxc
Regression potential: There should be none, since we are simply telling the
system-wide dnsmasq (if any) not to bind to the lxcbr0 which our own dnsmasq
instance will bind to.
==========================================
If dnsmasq is installed and running as default, it will bind all
interfaces. As a result lxc can't run dnsmasq against lxcbr0 (and
same with libvirt and virbr0).
At the least this should be documented in lxc. Preferably we'd find a
way to have dnsmasq be less of a bully.
