Netplan 配置的 LXD 主机在重启时不会恢复网络配置

我有一台 17.10 服务器，通过 snap（2 个容器）安装了 LXD。

我已将主机配置为具有静态 IP，并允许从 LAN 访问容器。

我的 01-netcfg.yaml 在 /etc/netplan 中：

network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: no
      dhcp6: no
  bridges:
    lxdbr0:
      dhcp4: no
      interfaces:
        - enp1s0
      addresses: [192.168.0.10/24]
      gateway4: 192.168.0.1
      nameservers:
        addresses: [192.168.0.1,8.8.8.8,8.8.4.4]
      parameters:
        stp: false
        forward-delay: 0

运行 sudo netplan apply 后一切正常，我可以从主机访问互联网。

ifconfig 给出以下内容：

重启后，主机中没有互联网（但是，LAN 子网内 ping 可以，容器中的互联网可以正常使用）。

ifconfig 显示的内容完全相同，只是 lxdbr0 广播 0.0.0.0 而不是原始值广播 192.168.0.255。

重启后运行 sudo netplan apply 后它会再次开始工作，并且 lxdbr0 的广播再次填充工作值。

有任何想法吗？

更新：安装了 NetworkManager 并尝试将其用作渲染器 - 没有效果，一切都像使用 networkd 一样工作 :(

复制于解决方案作为答案，因为我第一次看到这个（在评论中）时错过了它，感谢@user4124，将其标记为社区维基。

安装 LXD（仅限主机）

sudo apt remove --purge lxd lxd-client && apt install bridge-utils
sudo snap install lxd
sudo reboot
sudo lxd init

安装时，不要创建网桥。

设置主机网络

sudo nano /etc/netplan/01-netcfg.yaml

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: no
      dhcp6: no
  bridges:
    br0:
      dhcp4: no
      dhcp6: no
      interfaces:
        - enp1s0
      addresses: [ 192.168.0.2/24 ]
      gateway4: 192.168.0.1
      nameservers:
          addresses:
              - 192.168.0.1
              - 8.8.8.8
              - 8.8.4.4
      parameters:
          stp: false
          forward-delay: 0

sudo netplan --debug apply

重新启动并确认配置正确：

sudo reboot
ifconfig -a
ping google.com

编辑默认配置文件以确保配置中仅存在桥接器，没有额外的网卡

sudo lxc profile show default // add '> out.yaml' to output to file
sudo lxc profile edit default // add '< out.yaml' to read from file

示例 out.yaml：

### This is a yaml representation of the profile.
### Any line starting with a '# will be ignored.
###
### A profile consists of a set of configuration items followed by a set of
### devices.
###
### An example would look like:
### name: onenic
### config:
###   raw.lxc: lxc.aa_profile=unconfined
### devices:
###   eth0:
###     nictype: bridged
###     parent: lxdbr0
###     type: nic
###
### Note that the name is shown but cannot be changed

config: {}
description: Default LXD profile
devices:
  br0:
    nictype: bridged
    parent: br0
    type: nic
  root:
    path: /
    pool: default
    type: disk
name: default
used_by:
- /1.0/containers/apache

为容器设置网络

跑步：

sudo lxc exec <container> bash
nano /etc/netplan/50-cloud-init.yaml

插入：

network:
  version: 2
  ethernets:
    eth0:
      dhcp4: no
      dhcp6: no
      addresses:
        - 192.168.0.5/24
      gateway4: 192.168.0.1
      nameservers:
        addresses:
          - 192.168.0.1
          - 8.8.8.8

    netplan --debug apply
