Title:
  Support IPv6 in Libvirt LXC

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Libvirt's LXC implementation exposes a read-only `/proc/sys/net` to
  guests.

  This can cause guest's default network configuration scripts to fail
  when trying to bring up `IPv6` interfaces.

  The short-term fix is to use `postup-hooks` to configure the
  interface.

  Longer-term, we may want to consider a writable `/proc/sys/net` (we
  just need to verify that this can be done securely).
