[ovn][wallaby][migration] Live migration more than 10s switchover
Hello community, We are running a Wallaby TripleO installation with OVN networking. During live migration, we’re experiencing a connectivity outage lasting between *10 and 40 seconds* on the provider network to which the migrating VM is connected. I don’t see any errors in the ovn-controller, nova, or neutron logs. Is this behavior normal for the Wallaby release? We don’t see this issue in our Kolla-Ansible deployment running OpenStack 2024.2. I found that OVN multi-chassis port bindings were not yet implemented in Wallaby, but still — more than 10 seconds of downtime during live migration seems excessive. Has anyone observed similar behavior with older OpenStack releases, or is there any way to tune or optimize the switchover to reduce the outage duration? Thanks for any advice. Best regards, Kamil
