We use the 'dummy' interface for this. 'modprobe dummy' and now you've
got 'dummy0' as an interface on the host. (You can also have dummy1,
dummy2, etc. by running 'modprobe numdummies=X' where 'X' is the number
of dummy interfaces you want.)
You can treat this just like any other interface on the host and assign
a different IP address to each guest and you have a truly host-only
networking device.
