VXLAN 인터페이스가 브리지에 연결된 CentOS 7 서버가 있습니다. 서버가 네트워크 서비스를 사용하고 있습니다. 네트워크 관리자가 설치되지 않았습니다. 이 /sbin/ifup-local스크립트는 브리지가 시작된 후 VXLAN 인터페이스를 설정합니다.
#!/bin/bash
# Set up VXLAN once cloudbr0 is available.
if [[ "$1" == "cloudbr0" ]]
then
ip link add vxlan100 type vxlan id 100 dstport 4789 group "240.10.11.1" dev "eth0"
brctl addif cloudbr0 vxlan100
ip link set up dev vxlan100
fi
잠시 동안 작동한 후 VXLAN 인터페이스가 사라졌습니다. 원인을 찾고 해결하는 데 도움이 필요합니다. 나는 이것을 에서 보았다 /var/log/messages.

실행 중은 systemctl status network네트워크 서비스의 가동 시간이 길다는 것을 보여줍니다(인터페이스가 사라진 후보다 훨씬 길어짐). systemctl restart network누락된 인터페이스를 다시 존재하게 만드는 데 성공했습니다. 그러다가 잠시 후 인터페이스가 다시 사라졌습니다.
인터페이스가 사라진 이유를 아시나요? 다른 인터페이스는 계속 작동합니다. 인터페이스를 구성하는 보다 안정적인 방법이 있습니까?

답변1
서버가 유휴 상태일 때 이 문제를 본 적이 없습니다. 또한 /var/log/messagesCloudStack이 VM을 종료하고 관련 네트워크 인터페이스를 삭제할 때 vxlan100 인터페이스가 항상 삭제된다는 점도 확인했습니다 . CloudStack이 때때로 인터페이스 이름에 패턴 일치를 사용한다는 것을 알고 인터페이스 이름을 vxlan100에서 ethvxlan0으로 변경했습니다. 그 이후로 안정적이었습니다.
CloudStack이 API를 네트워크 인터페이스에 바인딩할 때 이름이 eth*, bond*, team*, vlan*, em*, p*p*, ens*, eno*, enp* 또는 enx *와 일치하는 인터페이스만 사용합니다. 이러한 패턴 중 하나와 일치하지 않는 모든 인터페이스를 제거하는 정리 루틴이 있는지 궁금합니다.
vxlan100이라는 이름은 CloudStack 로그에 나타나지 않습니다. 이것이 CloudStack 버그라는 증거는 없지만 현재로서는 이것이 최선의 추측입니다.
