提供迷航框需要多次尝试。

疯狂:一而再、再而三地做同样的事情，期待着不同的结果。--爱因斯坦

我有一个流浪汉+厨师(w/厨师-零伯克架)构建的盒子，运行许多程序，包括，mongos和erlang。我使用的是流行的烹饪书，由伯克希尔管理，还有一个基本的CentOS 6盒(存储在我当地的Mac上)。第一次(在vagrant destroy之后)启动此框通常需要多次尝试。vagrant up将在上面列出的一个程序上失败，我将不得不一遍又一遍地运行vagrant provision (有时多达6次)，才能顺利完成整个构建过程。然而，在罕见的情况下，星星对齐，每件事都激发了第一次尝试。

我看到的错误通常是显式超时错误(尽管并不总是如此)。我通常是在一个相当弱的office网络连接(低于20 Mbps )上运行这一点，这也许可以解释为什么在最大的下载中会出现故障。

我的问题是:首先，除了网络连接之外，还有其他变量可以解释为什么我必须多次使用vagrant provision吗？如果是这样，我如何测试和治疗它？第二，是否有一种方法可以让流浪汉继续提供服务，直到它取得成功？我还没有找到这样做的有记录的标志/设置，但我觉得可能会有一个.

谢谢你的帮助。

带宽、CPU、I/O、bug都可能导致资源汇聚时间的增加，从而导致超时。尝试将资源增加到VM (CPU、RAM)，如果可能的话，在主机上使用SSD，等等。

至于在vagrant provision成功之前运行它，您可能只需将它封装在一个while循环中：

false; while [ "$?" -ne "0" ]; do vagrant provision; done
