그렇게 하면 systemctl restart network가상 인터페이스(vi1, vi2, vnet0-vnet3)의 브리지 종속화가 지속되지 않으며 각 가상 인터페이스를 다시 종속화해야 합니다. 나는 가상 인터페이스를 노예화하는 데 사용합니다 ip link set vnet3 master vb4.
서비스와 컴퓨터 다시 시작 사이에 가상 인터페이스 브리지 노예화를 유지하는 방법은 무엇입니까?
답변1
이렇게 하면 systemctl restart network모든 네트워크 구성이 지워집니다. 이 작업을 수행하면 생성한 모든 브리지가 종료되고 다시 시작됩니다.
가상 머신을 시작한 후에는 libvirtd네트워크를 모니터링하지 마십시오.
따라서 일부 네트워크 인터페이스를 다시 연결해야 합니다.
모든 가상 머신의 재시작을 테스트해야 하며 문제가 없으면 서버를 재시작할 수 있습니다.
