Understanding Live Migration (L2 network)

Hi folks,

I hope everything is well.

Sorry about that doubt in this channel.

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 two packets (RARP and ICMPv6). "This packet is created by qemu ? "

Does anyone know if there is documentation on this?
