VirtualHost in apache

Finally understand it after reading:

I was having lotsa trouble understanding why wasn't my rules applying to the vhost I was setting up. But after reading that I know you weren't suppose to create multiple NameVirtualHost entry. Just one. The ServerName inside the VirtualHost block will determine whether that block applies to the query or not.
