I hope everything is well.
I have a doubt about live migration interacting with layer 2 network, when the live migration is running. How does the qemu signal the switch network that the qemu instance changes port ? Because when the qemu migration to another port switch, the switch has a time to understand that flow is changed.
I saw the dump traffic in live migration and I noticed that one packet (RARP). "This packet is created by qemu."
Does anyone know if there is documentation on this?
