lxcコンテナを起動しようとするとエラーが発生します。ところで私はLXDを使っています。私が直面したエラーは次のとおりです。
ubuntu@ubuntu-blade1:~$ sudo lxc start test
error: Error calling 'lxd forkstart test /var/lib/lxd/containers /var/log/lxd/test/lxc.conf': err='exit status 1'
Try `lxc info --show-log test` for more info
ログを確認してみると次のような内容がありました。

設定にlxdbr0があることを確認できますか？ LXDが提供するサーバーに加えて、このシステムにDNSまたはDHCPサーバーがインストールされていますか？ dnsmasqをインストールした後も同じ問題が発生し、sudo apt-get remove dnsmasq再起動後にすべてがうまく機能します。 LXDブリッジが実行されるように再構成する必要があるかもしれませんsudo dpkg-reconfigure -p medium lxd。製本インストール後、それを削除してLXDブリッジを再構成する必要があるかもしれません。
