    touch /etc/.pve-ignore.resolv.conf

首先防止 pve 覆写我们的配置

然后安装 systemd-resolved

    vi /etc/systemd/resolved.conf

修改 resolved 的配置

    ln -sf ../run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

将 /etc/resolv.conf 设置成由 resolved 维护

    resolvectl default-route eth0 no

禁用 default route，否则 dns 请求还是会走网卡从 dhcp 搞来的地址……不知道重启还有没有用

答案是重启就没了，要搭配这个使用
