UPDATE: The result of this looks like this:

UPDATE:

dnsmasq is assigning the ip correct:

What then happens is an arp storm for the gateway. My router is answering the arp reply, but the vm keeps asking (~500 times/s) for the arp.

Still trying to get more information, but its very weird (since it worked before)
