Title:
  lxc postinst incorrectly chooses network address to use

Status in lxc package in Ubuntu:
  Triaged

Bug description:
  The lxc postinst assumes that only /24 networks are used in
  10.0.0.0/8.  If the host has a route for 10.0.0.2/23 (or 10.0.0.0/22,
  or any other block that includes 10.0.3.0/24 or whatever other block
  it is checking) then the postinst chooses a chunk of the existing
  network block, breaking connectivity.
