    Exit to collection view if the VM goes to a non-running state
    
    This is required for instance for the SLEEP and PAUSE mode, as
    in these modes we can't use the spice display widget, but the
    spice connection is not disconnected, so we don't currrently
    exit to the collection view due to that.
