I am collecting port 67 traffic on the dhcp server since this afternoon. I hope to be able to find out more.
further testing revealed that dhclient really asks for the wrong ip (but always sends the client-identifier), and this is due to the poisoned leases file. I am now using /dev/null as leases file for all the virtual dhclients, but I wonder if this disables the entire "keep the old lease" system (which I don't really need) or it simply stays only in memory, which won't really solve the problem.
