我有一台运行 CentOS 的虚拟机，它只连接了一个虚拟适配器。
但是，如果您查看详细信息，您会看到以下内容：
我只想要/需要 10.1.xx 地址。其他人从哪里来？它们可以安全地移除吗？ 如果是这样，怎么办？
这是一个 ifconfig：

答案1
其他 IP 地址对应于虚拟机内部的网桥，大概是为虚拟机内部的容器和其他虚拟机提供网络连接。要“删除”这些 IP 地址，您必须删除相应的网桥，但如果有是虚拟机内有用的容器和虚拟机，并且您需要访问它们，但您不应该这样做。
或者，您也可以尝试将所有虚拟机内部网络重新配置为专用，IE不要使用连接到 NIC 的网桥，并对需要退出 VM 的所有内容使用 NAT。
