The VMs have the same IP for some reason I cannot yet explain... but I guess that explains the brokenness at least :D.
@Bubu maybe giving each VM a fixed IP addres? If they have a different MAC-addres, the DNS-server can be used to fix these. I don't have much experience with VM's, but this is what I do with physical devices.
@thaha yeah, that's what I went this in the end. Managing static ips is a PITA but certainly beats debugging a dns server for now :).
