$docker-machine ls

给我

NAME      ACTIVE   DRIVER       STATE     URL   SWARM
default            virtualBox   Timeout

如果我在Docker ToolBox中运行start.sh,我会得到

##         .
              ## ## ##        ==
           ## ## ## ## ##    ===
       /"""""""""""""""""\___/ ===
  ~~~ {~~ ~~~~ ~~~ ~~~~ ~~~ ~ /  ===- ~~~
       \______ o           __/
         \    \         __/
          \____\_______/

host is not running
docker is configured to use the default machine with IP

这个州意味着什么？
