cloud-initがメタデータサーバーを見つけられない（Openstack）

サーバーがメタデータサーバーへの接続に失敗している（そのため、SSHキーでログインできない）理由を理解しようとしています。

オンラインでの同様の問題は セキュリティグループの問題 が原因であるようですが、ここでは問題ではないと確信しています。

これは、IPが192.168.160.100の単一のホストです。ゲストには10.225.134.63の固定IPが与えられます。ネットワークの10.225.134.64にneutron DHCPサーバーがあります。

ホストでは、次のコマンドを実行しました。

# curl http://192.168.160.100:8775
1.0

2008-09-01
2009-04-04

# curl http://169.254.169.254
curl: (7) Failed connect to 169.254.169.254:80; No route to Host

私も同じ問題に直面したため、インスタンスを再起動しようとしましたが、しばらくするとRoute Ipv4情報で、インスタンスがメタデータを取得しようとしている3番目の宛先を識別できます。これは問題の正確な解決策ではなく、一種の代替策です。
