无法从 Ubuntu 主机访问 Vagrant 提供的 VirtualBox VM

Question

我正在关注 basic Vagrant tutorial，而 Vagrant 在我的 Ubuntu 上提供了一个框，没有抱怨。而且，我可以vagrant ssh进入虚拟机。但是，无法从主机访问 VM：无法 ping 它的 IP 地址。

我的收获：

已安装 VirtualBox (5.1.24 r117012 (Qt5.5.1)) 和 Vagrant (1.9.7) 到我的 Ubuntu (16.04.2 LTS) 机器上。
为虚拟机配置 vagrant up，Vagrant 完成了工作并且没有抱怨。
vagrant ssh 有效。
我已在来宾 VM 上手动安装 lighttpd，我可以从来宾 VM 中成功 ping/curl 地址：localhost。

这是我尝试从主机访问来宾 VM 时得到的结果：

~/tmp/myfirstvagrantproject$ ping 172.22.22.22
PING 172.22.22.22 (172.22.22.22) 56(84) bytes of data.
From ... icmp_seq=4 Destination Net Unreachable
...
171 packets transmitted, 0 received, +21 errors, 100% packet loss, time 173411ms

工件如下：

1.Vagrantfile:

  # but please keep it within the IPv4 private network range

  # The project name is base for directories, hostname and alike
  project_name = "projectname"


# Vagrant configuration

  Vagrant.configure("2") do |config|


    # Define VM box to use
    config.vm.box = "precise32"
    config.vm.box_url = "http://files.vagrantup.com/precise32.box"

    # Set share folder


    # Use hostonly network with a static IP Address and enable

    config.hostmanager.enabled = true
    config.hostmanager.manage_host = true
    config.vm.define project_name do |node|
      node.vm.hostname = project_name + ".local"
      node.vm.network :private_network, ip: ip_address
      node.hostmanager.aliases = [ "www." + project_name + ".local" ]
    end
    config.vm.provision :hostmanager



 end

适配器 1。附加到：NAT
适配器 2。连接到：仅主机适配器 vboxnet0，已连接电缆 - 是。

问题：如何配置 Vagrant/VirtualBox 以将 IP/port 暴露给主机 OS？

Answer 1

这是由于 a bug in VirtualBox 5.1.24 and has been fixed in 5.1.26. You can take a look at my 提供的更多详细信息。归根结底，VirtualBox 5.1.24 无法在内核路由 table 中为 vagrantfile 中定义的专用网络创建路由。

升级到 VirtualBox 5.1.26 应该可以解决您的问题。
