Using VMware:
This is because the guest hosts all share the same virtual network
device on the host. I had this problem when setting up some honeypots
using vmware. I solved the problem by making new vmware virtual network
devices and putting the guests on separate devices.

There is one problem with this approach that I haven't really had the
time to investigate --- the guest hosts in this system will not be able
to communicate with each other...
