Hi, I get this bug too! After upgrading to OpenStack 2026.1 (Kolla-Ansible, ML2/OVN), our Keepalived VIP becomes unreachable after some time.
VIP configured using allowed_address_pairs on two VM ports. Port security enabled. No virtual MAC or dedicated VIP port is used. No Keepalived MASTER failover occurs. The same configuration worked fine before upgrading to 2026.1. Observed behavior: Initially, the VIP is reachable. After some time, the VIP becomes unreachable. Restarting Keepalived restores VIP connectivity, but the issue occurs again later. As a workaround, we disabled port_security_enabled on the affected Neutron ports, and the issue has not recurred. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2169909 Title: [SRU] ovn 26.03.0 drops ARP requests from localnet to VMs on non- gateway chassis when the provider network has a router gateway (fixed in 26.03.2) To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/2169909/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
