안녕 친구들. 오늘 이 문제에 대해 또 다른 스레드를 설정했지만 이제 더 많은 정보를 받고 어느 정도 진전을 이루었으므로 이전 스레드와는 거의 관련이 없습니다. Fedora 31에서 브리지를 만드는 데 어려움을 겪었지만 마침내 작동하게 되었습니다. 튜토리얼을 10개 정도 들었는데 지금은 어느 정도 효과가 있습니다. 내 목표는 가상 머신을 로컬 네트워크에 전달하는 것이므로 네트워크 brdige br0이 네트워크의 dhcp 서버를 사용하여 내 컴퓨터의 IP 주소를 가져오길 원합니다. 간단한 라우터. 불행히도 문제가 발생하여 해결책을 찾을 수 없습니다.
내 nmcli connection show출력은 다음과 같습니다
[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
enp0s8은 br0 브리지에 사용하려는 인터페이스입니다. 따라서 물리적 LAN에 연결된 2개의 물리적 네트워크 인터페이스가 있습니다.
그래서 전부 꺼내어 보았는데 괜찮아 보였는데 아쉽게도 IP 주소를 가져오는 과정에서 프로세스가 막히는 것 같았습니다. 또한, 이 주제에 대한 정보를 얻는 것이 매우 어렵기 때문에 해결책이 없으면 누군가에게 비용을 지불해야 하지만 누군가가 도움을 줄 수 있을 것이라고 확신합니다 :)

고정 IP 할당을 시도했지만 제대로 작동했지만 네트워킹, 특히 가상 머신 및 브리지와 같은 복잡한 것에 대해 많이 이해하지 못합니다. 이제 br0 인터페이스에 IP가 할당되었지만 가상 머신 내부에는 여전히 인터넷 연결이 없습니다.

이제 모든 것을 재설정하고 새 브리지를 만든 후 IPv4 주소가 VM에 할당되지만 VM 내부에서는 네트워크나 인터넷에 액세스할 수 없습니다.
호스트 이름은 LAN 내부에도 나타납니다.
