NIC 有错误的 MAC 地址和 "systemd-udevd: error changing net interface name ethX to ethY: File exists"

Solution In Progress - Updated -

Issue

  • 我们已在 ifcfg 文件中设置了 HWADDR，来为每个接口分配特定的名称，但无法正常工作。
  • 尝试为每个接口指定特定名称，如 eth0 或 eth1。

  • 查找这些错误消息以及在 ifconfig 中显示错误 MAC 的接口。

    systemd-udevd: error changing net interface name eth0 to eth1: File exists
    systemd-udevd: error changing net interface name eth1 to eth0: File exists

  • 在 IBM System z (s390x) 系统中查找这些错误消息：

    systemd-udevd: Error changing net interface name 'hsi2' to 'hsi3': File exists
    systemd-udevd: could not rename interface '5' from 'hsi2' to 'hsi3': File exists
