Using internal networks is probably possible as well but indeed I don't
see any reason why we shouldn't support more than 8 host-only network
interfaces. There is already a defect open for this and sooner or later
this will be fixed (there is also the issue of restoring the host-only
interfaces after eboot of the host).
