Bonjour,
Après avoir poussé la configuration ifupdown dans le fichier d’interfaces et redémarré le service networking, le switch OvS se monte bien, je peux faire un ping à travers le trunk ens19 vers le tunnel gre. Mais lorsque je redémarre la VM, le service réseau démarre sans erreur, le commutateur OvS est construit mais rien n’est transmis. Je dois redémarrer le service networking après avoir démonté la VM pour que les flux soient à nouveau transmis. Il n’y a pas d’erreur dans les logs et je ne vois pas ce que je peux faire pour résoudre ce problème. Quelqu’un a-t-il une idée ?
Merci
Debian 12 Bookworm - 6.1.0-10-amd64 avec systemd (252.6-1), ifupdown (0.8.41) et openvswitch (3.1.0-2)

Voici le diagramme du réseau, j’essaie de faire un ping depuis VM1 sur l’interface vmbr0 du VPS qui a l’IP de test 10.0.64.11.
Après le redémarrage de VM2, le ping ne fonctionne pas, mais après un systemctl restart networking.service, le ping fonctionne à nouveau.
J’ai le même comportement sans passer par ifupdown et en configurant à la main avec ip-link et ovs-vsctl (après chaque redémarrage, je dois détruire le pont OvS3 et le reconstruire). De plus la directive address de l’interface vmbr0 n’est pas appliquée par ifupdown, cette interface ne prend pas l’ip 10.0.64.10 …
