Bug Description

When an LXC/LXD container is no longer needed, it should be frozen instead of shut down by the respective container manager.

This will make "start up" of the container much faster and will be particularly useful for LXD containers that take a very long time to start when fully stopped.

Also of note, memory usage will remain the same since the frozen container will still reside in memory. Possibly making this a configuration option of a container will allow users who want to free memory when a container is not needed is necessary???

This bug was fixed in the package libertine - 1.6+17.04.20170209-0ubuntu1

---------------
libertine (1.6+17.04.20170209-0ubuntu1) zesty; urgency=medium

  [ Larry Price ]
  * Get libertine-container-manager and libertine-launch working in a confined
    environment.
  * Create a special desktop file to satisfy the snappy store.
  * Update snap definition to include aliases, renamed commands, and internal
    desktop file.
  * Ensure absolute path lxd bind-mounts have a valid name by using the full
    path as a backup.
  * Refactor liblibertine as a client wrapper for libertined and bump version
    to 1.5.2.
  * Protect against containers that aren't started when running commands.
  * Migrate the list-apps subcommand to list application ids. (LP: #1657877)
  * Run the libertined integration test with its own dbus sesison to prevent
    collisions with running service.

  [ Chris Townsend ]
  * Discover if a session is running and if so, use it's dbus session to start
    the container manager. (LP: #1657490)
  * Replace all pylxd execute()'s with calls to 'lxc exec' as pylxd has
    performance issues in execute().
  * Add ability to freeze and unfreeze LXC/LXD containers. This is disabled by
    default for now. (LP: #1654355)
  * Add ability to enable and disable the freezing of LXC/LXD containers when
    not in use. (LP: #1654355)
  * Deprecate the lx[cd] managers and use libertined for managing the containers
    and move the actual starting and stopping of containers to the respective
    backends. (LP: #1660685)
  * Add a restart subcommand to libertine-container-manager. Also try to restart
    the container when adding/removing bind-mounts, if appropriate.
    (LP: #1654355)
  * Enable Xmir '-rootless' mode by default and remove using Matchbox for the
    window manager. (LP: #1662555)
  * Change when the libertine-xmir Upstart gets started to account for Unity 8
    now directly starting apps.
  * Bump release version to 1.6.
