Looks like the proper syntax for the listen-on named config is  either


Just tested on MAAS dns service which fails > 75% of the time when brought up in a vm due to timing issues.

The proposed  "listen-on { ! 10.0.3.1; };"   cannot be parsed by bind
because ! is supposed to be outside the address list match element.
(per http://www.zytrax.com/books/dns/ch7/address_match_list.html)


I think the fix should be:

listen-on ! { 10.0.3.1; };

With this setting in my maas dns/bind conf, bind comes up without error
and I don't get collisions with lxc ips on the system.

Title:
  Bridge not created if bind9 is on

Status in bind9 package in Ubuntu:
  Confirmed
Status in lxc package in Ubuntu:
  Confirmed

Bug description:
  LXC will not create the lxcbr0 bridge if bind9 is on, as it can not
  take the 10.0.3.1 address. If bind9 is stopped, then LXC successfully
  creates the bridge.

  Expected result: LXC will create the bridge, even if bind9 is on.
