Vagrant:无法从主机ping客户机

Question

我有安装了vagrant的Mac OS.在客机上我有Ubuntu 12.所以,我想做的是从主机ping客户机.

连接到NAT的来宾机(根据VirtualBox设置)

我在客机上找到了一个接口(lo除外):

eth0      Link encap:Ethernet  HWaddr 08:00:27:88:0c:a6  
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe88:ca6/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:581 errors:0 dropped:0 overruns:0 frame:0
          TX packets:410 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:61376 (61.3 KB)  TX bytes:51599 (51.5 KB)

问题是主机上的10.0.2.*网络中没有IP地址.主机有几个vboxnet接口,但它们都没有任何ip地址:

vboxnet0: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          ether 0a:00:27:00:00:00 
vboxnet1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          ether 0a:00:27:00:00:01 
vboxnet2: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          ether 0a:00:27:00:00:02 
vboxnet3: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          ether 0a:00:27:00:00:03 

您是否知道为什么VirtualBox没有将ip地址分配给主机？我能做些什么才能ping阵风？

这是我的流浪文件(我删除了一些我不使用的注释行):

默认情况下(即,当不接触任何网络配置时),Vagrant在VirtualBox中配置VM以将其第一个接口(eth0)附加到" NAT "(不要将其与" NAT网络 " 混淆,后者是VirtualBox中的不同选项).

当您的VM接口连接到NAT时,guest虚拟机将获得10.0.2.15 IP.在主机端,您只能看到没有IP的vboxnet #interface.您可以将此接口视为该guest虚拟机的专用路由器.

连接到NAT的VM不可从外部路由.这是设计上的,这也是vboxnet #interface没有IP的原因之一.虚拟机能够访问"外部世界",例如互联网和主机,但无法在没有端口转发的情况下从外部访问.

如果默认行为不是您要查找的,Vagrant提供网络配置的高级抽象:

1. 专用网络 - 这将创建不应与主机的子网(或主机可能路由到的任何其他子网)发生冲突的新子网.在VirtualBox中,这将通过将附加接口附加到" 仅主机 " 来配置.
2. 公共网络 - 您的VM将从与主机相同的子网获取IP.基本上这就像在与主机相同的网络上创建新机器.在VirtualBox中,这将通过将附加接口附加到" 桥接适配器 " 来配置.

通过提供商特定配置配置网络,可以实现更高级的网络配置.

每个配置都有它自己的优点和缺点,这实际上取决于你计划实现的目标.有关其他信息,请查看VirtualBox关于网络的文档.

我不确定为什么您在来宾上看到 IP 地址，但鉴于该 vagrant 文件，您根本没有配置任何 virtualbox 网络。您需要取消注释该config.vm.network "private network"行，然后配置 IP 地址。

virtualbox 的默认设置是将主机置于 10.0.0.2 并将整个 10.0.0.0/8 范围公开为本地地址，因此我认为 10.xxx 范围内的任何内容都适用于客户端虚拟机。
