If you set up host networking and attach all guest networks to a host bridge (see user manual for details), all guests receive an IP from your host's gateway and are attached to the same network as your host. I would prefer this way. The other choice is to configure two network interfaces for each guest: The first instance would be NAT (for the internet access) and the second instance would be an internal network (for communication between the guests). But this way the host would not be able to connect to the guest, except if you do some kind of port forwarding. In general, host networking is the preferred solution (for performance reasons).
