An interesting scenario

[Jonathan Aquilina]

I have an interesting scenario which either is already catered for or should 
be catered for.

I am currently using a local provider for testing and contribution purposes.

I bootstrapped an environment and deployed the juju-gui i then shut down the 
computer and powered it on again this morning the bootstrapped environment 
came up just fine yet the instance i created with the juju gui did not

jaquilina at jaquilina-Satellite-S75-A:~/.juju$ juju status
environment: local
machines:
  "0":
    agent-state: started
    agent-version: 1.16.5.1
    dns-name: 10.0.3.1
    instance-id: localhost
    series: saucy
  "1":
    agent-state: started
    agent-version: 1.16.5.1
    instance-id: jaquilina-local-machine-1
    instance-state: missing
    series: precise
services: {}
jaquilina at jaquilina-Satellite-S75-A:~/.juju$ sudo lxc-ls  --fancy
NAME                       STATE    IPV4       IPV6  AUTOSTART  
--------------------------------------------------------------
jaquilina-local-machine-1  RUNNING  10.0.3.50  -     YES    

As can be seen the instance state is missing. I removed the entire 
bootstrapped environment and recreated it again 

machines:
  "0":
    agent-state: started
    agent-version: 1.16.5.1
    dns-name: 10.0.3.1
    instance-id: localhost
    series: saucy
services: {}

Now the scenario is this. This is more for cloud providers as well as those 
hosting private clouds. But what does one do if you have a server which fails 
or power cycles itself for one reason or another. How will one bring back up 
the instances that were running on it?
