使用 systemd-networkd 配置桥接接口

使用 systemd-networkd 配置桥接接口

我正在尝试创建一个桥接口清除Linux与 systemd-network 最终将其用于 KVM。

我尝试创建以下文件作为这指导：

/etc/systemd/network/br0.netdev

[NetDev]
Name=br0
Kind=bridge

/etc/systemd/network/br0.network

[Match]
Name=br0

[Network]
Address=10.0.0.3/16
Gateway=10.0.0.1
DNS=10.0.0.1

上行网络

[Match]
Name=eno1

[Network]
Bridge=br0

重新启动后，brctl似乎暗示eno1接口未正确连接到br0：

bswinnerton@nuc7i3 /etc/systemd/network $ brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.429f5774d8b6       no

这是输出networkctl：

bswinnerton@nuc7i3 /etc/systemd/network $ sudo networkctl
IDX LINK             TYPE               OPERATIONAL SETUP
  1 lo               loopback           carrier     unmanaged
  2 br0              ether              no-carrier  configuring
  3 eno1             ether              routable    configured

3 links listed.

以及状态systemd-networkd：

bswinnerton@nuc7i3 /etc/systemd/network $ systemctl status systemd-networkd
● systemd-networkd.service - Network Service

Dec 19 22:46:13 nuc7i3 systemd-networkd[253]: eno1: Configured

我是否错误配置了文件？对于它的价值，我尝试过sudo brctl addbr br0，sudo brctl addif br0 eno1然后sudo systemctl restart systemd-networkd，一切都按预期工作，但在重新启动之间不会持续存在。

答案1

检查/lib/systemd/network/或中的配置文件/run/systemd/network，似乎有其他配置文件与您的eno1接口匹配并在其上启动 DHCP
