systemd-networkd 在克隆容器中未接收 DHCP IP

我正在试用 LXD，并从头开始创建了一个基本的 Arch Linux 映像。第一次使用该映像时，它运行良好，但克隆容器或重复使用该映像会导致 networkd 不广播 DHCP 请求。

日志没有提到任何有趣的内容 - LXD 的 dnsmasq 日志没有提到来自克隆容器的任何请求，networkd 的容器日志除了分配链接本地地址之外没有提到任何内容，工作容器日志也没有提到任何特殊内容。

解决方案比我想象的要简单——由于某种原因，接口交换了位置。

将无效的另一端eth1@if22与有效的进行比较eth1@if20：

20: veth7CJ8BF@if19: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master lxcbr0 state UP mode DEFAULT group default qlen 1000
    link/ether fe:ec:a2:e5:94:48 brd ff:ff:ff:ff:ff:ff link-netnsid 0
22: vethHK45MP@if21: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master br0 state UP mode DEFAULT group default qlen 1000
    link/ether fe:9b:42:ff:d7:99 brd ff:ff:ff:ff:ff:ff link-netnsid 3

name可以通过向 LXD 配置文件添加密钥来解决此问题。
