vagrant up 时出现 NFS 错误

Question

我每次游走客户环境时都会遇到这个错误：

    NFS requires a host-only network to be created.
    Please add a host-only network to the machine (with either DHCP or a
    static IP) for NFS to work.

这是我尝试 vagrant up 时的消息。紧接着就出现了错误信息：

    manager: Attempting graceful shutdown of VM...
    manager: Checking if box 'centos/7' is up to date...
    manager: Clearing any previously set forwarded ports...
    manager: Clearing any previously set network interfaces...

    manager: the port forwarding doesn't work. If any problems occur, please try a
    manager: port higher than 1024.

我做了一些研究并看到了类似的案例，但大多数答案都指出 vagrantfile 中缺少 config.vm.network。 我完全确定这里不是这种情况，因为我已经检查了 vagrantfile，我的同事可以在他们的 PC 上正常运行。

目前，我尝试重新安装 virtualbox (5.1.30)、vagrant (2.0.0)，但它不起作用。请帮助

Answer 1

我想出了我的问题：

基本上我的 Virtualbox 中的某些东西搞砸了，正在创建仅主机网络接口，但不知何故失去了与 virtualbox 的注册。以下是我所做的事情：

检查所有需要的 vagrant 插件（通常在 vagrantfile 中需要）
删除所有由 vagrant 创建的框。
删除所有NAT和host-only网卡并重新创建。
将仅主机网络的 Ipv4 地址更改为您要创建的正确地址之一（取决于您在 vagrantfile 中的配置）。在这种情况下，我还必须禁用 DHCP 服务器。

希望这对我在网上看到的一些类似案例有所帮助。这是 vagrant 和 virtualbox 的已知问题。
