为什么每次重启时网卡都会重命名？ - Ubuntu 20.04 LTS

2024-6-10 • tag-icon

原来是 enp4s0，现在是 enp10s0，原来是 enp9s0，现在是 enp5s0。

我害怕重新启动，因为这可能会破坏网络，直到我使用 KVM 连接它。

运行 Ubuntu 20.04 LTS。

由于我的 10G 网卡桥接为 br0，因此我不得不将其从 enp4s0 更改为 enp10s0 才能使其正常工作。这是配置，也许我弄错了。论坛将文本视为代码的方式会产生额外的空格，实际上我的 yaml 文件的空格是正确的。

    network:
  ethernets:
    enp10s0:
      dhcp4: no
    enp5s0:
      dhcp4: true
  version: 2

      interfaces: [enp10s0]

答案1

这是因为网络子系统没有与之前的启动硬件匹配。

我使用以下内容来给出一个一致的名称，而不管物理类型如何。

网络：以太网：eth0：dhcp4：false 匹配：macaddress：set-name：eth0 版本：2
