我想在本地机器上安装dc/os进行开发。
我按照这里的指示做了
打电话给流浪汉后，我得到警告：

some ports where in use ?

  m1:       Checking if port 42819 (required by spartan) is in use:
    m1:       PASS
    m1:       Checking if port 43911 (required by minuteman) is in use:
    m1:       PASS
    m1:       Checking if port 46839 (required by metronome) is in use:

    m1:       PASS
    m1:       Checking if port 62080 (required by navstar) is in use:
    m1:       PASS

最后又有两个警告：它们不应该是这里解释的问题

p1:       PASS
    p1:       Checking Docker is configured with a production storage driver:

我只是按照github上的说明，在windows10上安装了virtualbox和vagrant。
为什么我不能访问http://m1.dcos ? 警告是什么？
