Are you going to continue to use virtual IP addresses?  Cyrus strips the 
first part of the FQDN as the local name and leaves the rest as the 
domain.  So if you use names like:

If this doesn't work for you and have a better way of determining the 
domain from the IP address, I'm all ears.  The most complaints that 
we've had about the virt domains code, is the domain-from-IP half.
