当我重新启动我的 LXC 环境时，容器不会重新绑定到 IP 地址

Question

IP 不再响应远程 ping

重启我的意思是：

lxc-stop -n vm3
lxc-start -n vm3 -f /etc/lxc/vm3.conf -d

您正在撰写有关Linux 容器 (LXC) 的文章。您可以在容器的配置文件中分配静态 IP 地址。这是我的环境中的一个示例：

lxc.utsname = MPG_Web
lxc.tty = 4
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.mtu = 1500
lxc.network.ipv4 = 172.16.16.110
lxc.network.hwaddr = 00:30:6E:08:EC:80
lxc.rootfs = /srv/lxc/MPG_Web
lxc.mount = /etc/lxc/MPG_Web.fstab

您似乎缺少lxc.network.ipv4设置中的指令。

不幸的是，您需要使用脚本来注入默认和静态路由。这不能从 LXC 配置文件（还）控制。
