[Bug 1240757] Re: Bridge not created if bind9 is on

[ogai]

This bug just hit me in Ubuntu 14.04 LTS and is quite serious because
LTS is used in servers, and it is common to try to have virtualization
(LXC) as well as being configured as DNS servers (bind9).

Additionally, under some configurations at least, the whole DNS
resolving becomes malfunctioning as 10.0.3.1 is the first entry in
/etc/resolv.conf (put by resolvconf / dnsmasq) but it is not accessible.
As a result, any DNS resolving wait some seconds for a timeout!

A detailed workaround without reboot:

1. Add this line in /etc/bind/named.conf.options before the last line::

    listen-on { ! 10.0.3.1; };

2. Restart bind9::

    service bind9 restart

3. Restart the LXC network::

    service lxc-net restart
