我已经使用 virtualbox 在 centos 5.7 服务器上创建了 ubuntu vm。连接远程桌面没有任何问题。但我的问题是我不知道如何在主机和客户操作系统之间设置连接，以便客户操作系统（Ubuntu 10.04 服务器）可以访问主机操作系统（centos 5.7）的互联网。
下面是我的一些命令的输出。

请告诉我我需要做什么？

答案1
如果您只想访问主机的互联网，请将客户机的虚拟网络适配器类型从“桥接”更改为“NAT”。如果出于某种原因，您的客户机需要从与主机相同的网络进行访问，您可以调整 NAT 设置以将某些端口转发给客户机。
从您的日志来看，由于某种原因，您的客户机似乎没有在桥接适配器上分配 IP 地址。如果您需要与客户机和主机建立持久连接，我建议添加第二个虚拟网卡并将其设置为仅主机模式。
