如何从 lxd 主机启用 lxd 主机名解析？
创建以下容器后：
>>> lxc launch ubuntu: container
Creating container
Starting container
>>> lxc list
+-----------------+---------+----------------------+------+------------+-----------+
| container | RUNNING | 10.240.38.157 (eth0) | | PERSISTENT | 0 |
+-----------------+---------+----------------------+------+------------+-----------+
可以使用 IP 地址但不能使用主机名访问：
>>> ping 10.240.38.157 -c 3
