 - Maybe direct call to 'if (!runstate_check(RUN_STATE_RUNNING))' is better?  
   runstate_is_running too invokes the same. Not sure why are there two
   functions 'runstate_is_running' & 'runstate_check'.
 - Can't -> Can not
 - "...the Virtual Machine.." -> "...virtual machine.." (not capitalised)
 - "...when it isn't.." -> "as it is not..."
 - OR maybe just say -> "Virtual machine is not running"
