这样就是连不上网了

要么连不上网 要么 dns有问题

<已解决>ip 设置问题 谢谢大家
看来你的问题还没解决啊，如上的结果显示你的那个虚拟机根本没通外网！
先去解决那个帖子吧！

我找到问题关键了 看了很多资料 介绍 是我 我添加了网卡二 但是网卡二显示不出来 只有一个网卡eth0连接外网 但是就是加不上eth1 所以在eth0实现连接内网情况下 网卡模式该来改来改去都是实现不了连接不了外网。因为没有另一个网卡来实现连接外网的eth1

网卡添加不上啊 我试试改改配置文件吧

在<已解决>ip 设置问题 谢谢大家第一楼的图中显示你似乎手动修改过/etc/network/interfaces文件，在其中添加了eth0的相关配置，请问图中显示的eth0相关配置是否是你手动添上去的，还是文件中原本就有的？

在我的虚拟机debian8系统中，也是配置了两块网卡，但是/etc/network/interfaces文件中并没有两块网卡的相关信息，却照样能正常ping通宿主机和外网。
所以是否是你手动改了该配置文件，在其中只添加了eth0，而该配置文件的优先级又高，所以导致你的ifconfig命令只显示eth0 ？


如果是这样，你干脆删除添加的内容试试。

vbox安装好就只有一快网卡，就是host-0l。。在windows7里，的虚拟机网卡就自带了一个，我在设置网卡里添加第二块网卡，但是不起作用。进入ubuntu14.04 输入ifconfig下边只显示一个eth0和一个没啥作用的lo 这两个，想要的eth1没有出现

1. 每一個 Guest可以增設 最多達 8 個 虛擬網卡
前面四個 可以在桌面右上方 NM-Applet 增設
後面四個 可以在 /etc/network/interfaces 增設

啟用網路卡 打勾
打開進階 / 介面卡類型 / 選擇合適的網卡類型 (需要配合 Host 的作業系統)

4. 本持越簡單越容易搞定的原則
意思是 如果一個虛擬網卡 選擇合適的硬件類型 選擇合適的網卡模式
就可以達到的功能 就不必設 2 個虛擬網卡 來達到同樣的功能

5. 詳讀以上 官方使用說明書 再動手

vbox安装好就只有一快网卡,就是host-0l

不懂什么意思
如下图，我给我的虚拟debian添了3个网卡：

那么在虚拟debian中就显示为3块网卡：

其中网卡3我选择的是仅主机(host-only)适配器，所以从图中看出eth2分配的是192.168.56.x.

我不知道你的ubuntu为什么会读不到eth1 和eth2
你试试如下方法：

删除所有以太网连接，然后重启NerworkManager

我不知到ubuntu14.04重启NerworkMangager的命令是什么了，你自己查一下。
