Title:
  lxc postinst script checks available interfaces, can choose

Status in lxc package in Ubuntu:
  Confirmed

Bug description:
  The released wily image preinstalls lxc, which breaks the assumption
  that lxc's preinst packaging script makes:

  It inspects the network to try to pick a 10.0.N.0 network that isn't
  being used, with N starting at 3, so this appears to have picked
  10.0.3.0 when it was installed on whatever system was generating the
  image. This conflicts with the network that eth0 gets attached to when
  the image is brought up in a container, because it gets attached to
  the host's lxcbr0, which is using 10.0.3.x.

  This affects LXC, and should affect LXD but doesn't currently. (see #2)
  The easiest way to reproduce this is to use the ubuntu-cloud lxc template on a wily host:

  sudo lxc-create -t ubuntu-cloud -n wily
  sudo lxc-start -n wily
  sudo lxc-attach -n wily
  # inside container, test connectivity, eg:
  apt-get update
