OVN-Kubernetes secondary networks present packet loss during live migrations.

4.16

Always

1. Configure a localnet NAD according to the documentation example: https://docs.redhat.com/en/documentation/openshift_container_platform/4.17/html/virtualization/networking#virt-creating-localnet-nad-cli_virt-connecting-vm-to-ovn-secondary-network
2. Create a VM and connect it to the NAD
3. From another device that has access to the VM just created, start a ping to the IP address of the VM (the one configured for the interface connected to the NAD)
4. In OpenShift, live migrate the VM

Some ping packets will be lost during live migration

No ping packet should be lost, at least if the worker nodes running the VMs aren't too busy

Originally this was opened as a documentation bug, but as per Miguel's clarification, this isn't a documentation issue but a characteristic of OVN-K secondary networks.
