[pve-devel] arp question

[Dietmar Maurer]

A user reports an ARP cache problem:

http://forum.proxmox.com/threads/11637-refresh-the-arp-cache-after-a-online-migration

AFAIK, qemu-kvm sends gratuitous ARP:

see http://www.mail-archive.com/kvm@vger.kernel.org/msg40289.html

The code is in qemu-kvm/savevm.c: announce_self_create()

but that uses invalid IP 0.

So how is that expected to work? I have never observed such problems, so I wonder why
that works for me?
