こんにちは友達。今日はこの問題に別のスレッドを設定しましたが、今はより多くの情報を受け取り、ある程度進歩を遂げたので、以前のスレッドとはほとんど関係がありません。 Fedora 31でブリッジを作成するのに苦労しましたが、ようやく機能しました。チュートリアルを10個ほど聞きましたが、今はある程度効果があります。私の目標は、仮想マシンをローカルネットワークに転送することであるため、ネットワークbrdige br0はネットワーク上のdhcpサーバーを使用して自分のコンピュータのIPアドレスを取得したいと思います。シンプルなルーター。残念ながら、問題が発生して解決策が見つかりません。
私のnmcli connection show出力は次のとおりです
[root@localhost ~]# nmcli connection show
NAME UUID TYPE DEVICE
Bridge br0 d2d68553-f97e-7549-7a26-b34a26f29318 bridge br0
enp0s3 da37a9c2-f5a5-3a8a-b3ab-4ecd96031402 ethernet enp0s3
virbr0 898b66b6-22e1-4e46-9065-2fd67158731c bridge virbr0
enp0s8 00cb8299-feb9-55b6-a378-3fdc720e0bc6 ethernet enp0s8
enp0s8 は br0 ブリッジに使用するインターフェイスです。したがって、物理LANに接続されている2つの物理ネットワークインターフェイスがあります。
だから、すべて取り出してみましたが、大丈夫に見えましたが、残念ながらIPアドレスを取得する過程でプロセスが詰まっているようでした。また、このトピックに関する情報を取得するのは非常に難しいので、解決策がなければ誰かに支払う必要がありますが、誰かが助けることができると確信しています:)

ファイルを編集するときにBOOTPROTO=dhcpファイルを変更すると、BOOTPROTO=noneIPv6アドレスは受信されますが、IPv4アドレスは受信されません。
静的IP割り当てを試しましたが、うまく機能しましたが、ネットワーク、特に仮想マシンやブリッジなどの複雑なものについてはあまり理解していません。 br0インターフェイスにIPが割り当てられていますが、仮想マシンの内部にはまだインターネット接続がありません。

私は今日Cockpit Webインターフェイスを使用してブリッジを設定しようとしましたが、結果は次のようになりましたip addr showがnmcli connection show、残念ながらVM内にインターネット接続がありませんでした。
