Correct.  The hosts files are used according to the DOMAINLOOKUP 
specification in TCPIP DATA.  The default is to look in the hosts files 
only if not found in the DNS.  If you want to *override* a DNS entry, then 
you need to code "DOMAINLOOKUP FILES" so that the hosts files are searched 
before the DNS.

I should also say that unless you have very heavy usage of DNS, there's no 
point in running a caching name server on VM.  Just let the requests flow 
out to the network.  Linux can have its own DNS cache (man dnscache) and 
so won't benefit from a central cache.  The VM caching-only name server 
was designed for non-caching DNS clients such as CMS.
