I created a Wiki page for further discussion (so the ASCII Art
survives :-)). I would like to encourage you to do this for all
discussion so this mailing-list does not become to 'confusing'.
Well I'm not sure if copied and running are really different but it
might be interesting to know that a machine is copied (Although I cannot
think of a usecase right now).
Concerning the migrating I think that depends on how the VM is migrate
(live or not) To cover both I think adding a state is useful.
