NFSサーバーに移動した後、SSH公開/秘密鍵ペアは使用できません。

（2）他のVM間でホームディレクトリを移動すると、VMの1つではSSH公開/秘密鍵認証がめちゃくちゃになり、他のVMではそうでない理由を理解しようとします。すべてのローカルユーザーアカウントのホームディレクトリをNFSサーバーに移動します。/VM-ホーム/ユーザー名。現在のホームディレクトリをコピーしましたrsync-auvしたがって、権限は正しいです（$ HOME / .sshの場合は0700）。ホームディレクトリを変更した後/etc/パスワード、すべてのシステムを再起動しました。

ご覧のとおり、SSH接続はArcoLinuxでは期待どおりに機能しますが、CentOSでは失敗します。私はVirt-Managerを介してログインできるので、CentOSが私の新しい家を見ることを知っています。以前の家が使用されていないことを確認するために削除することもありました。別のVMの再構成を続行する前に、この問題を解決したいと思います。
