Configuring a service with no virtual hostname required

The special case virtual hostname NONE exists so a service can be configured without the need for a virtual host name (for example when only fiber channel is being served out). To configure such a service, firstly add the NONE virtual host name to the service, then remove all other virtual hostnames so that just the single NONE entry remains, then save the settings.
