Bug Description

stable (1.20) and devel (master) are broken by a commit that changes lxc. Only precise is affected. trusty and utopic are fine. I don't believe architecture is a factor

The essential error seen in the logs are
    machine-0: 2014-07-29 18:29:00 ERROR juju.container.lxc lxc.go:244 container failed to start: cannot determine the lxc-start version: exit status 1
    machine-0: 2014-07-29 18:29:00 ERROR juju.provisioner provisioner_task.go:420 cannot start instance for machine "1": cannot determine the lxc-start version: exit status 1

Once this error is experienced, juju doesn't not cleanup. The lxc containers are left stopped with confs in /etc/lxc/auto. The machine must be manually purged.

Since the first failure will leave broken containers subsequent retests will report the containers already exist. So besides this bug, it is clear juju is leaving a broken system behind.

The golxc library attempts to look at the --version flag to intelligently determine what flag to use to specify a console-file. It looks like in this particular version of lxc-start there is no --version flag. We will have to reconsider how to determine what the console-file flag is.
