I have installed networking-ovn from ubuntu cloud repository.
dpkg -l | grep ovn
ii networking-ovn-common 5.0.0-0ubuntu2~cloud0 all OpenStack virtual network service - OVN driver
ii python-networking-ovn 5.0.0-0ubuntu2~cloud0 all OpenStack virtual network service - OVN driver
This is not latest version for rocky release ( latest is 5.0.1). So I clone repo (with branch stable/rocky) then upgrade manualy
After that, I re-sync ovn database using this command:
neutron-ovn-db-sync-util --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --ovn-neutron_sync_mode repair
then all VM with Floating IPs loss 50% packets.
Step to re-proceduce:
1) install networking-ovn from ubuntu repo stable/rocky
2) Create VM with FIPs
3) upgrade to latest branch stable/rocky
4) resync with mode repair
Step to fix
1) stop ovsdb-nb-db
2) remove ovnnb_db.db
3) start ovsdb-nb-db
4) re-sync |

4) re-sync
Then re-associate FIPs
1) disassociate all floating IPs (release not required)
2) clear router's external gateway
3) re-add router's external gateway - all vms now have full connectivity
4) re-attach floating ips |
