Virtual hosts

[Nair, Murlidharan T]

I am trying to configure my httpd.conf to specify a virtual host. I have
not done this before. I am getting the following error 

[root at bioinformatics init.d]# ./httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd: [Sun Sep 17 10:22:55 2006] [error] VirtualHost
_default_:443 -- mixing * ports and non-* ports with a NameVirtualHost
address is not supported, proceeding with undefined results
                                                           [  OK  ]

Do I have to make an entry in the DNS record, specifying the virtual
host? Its the cname I guess correct?
Let me know if I have goofed up any where. 
Cheers ../Murli
