php - Virtual hosts with two servers on localhost -

I have two Apache web servers running on my laptop running Windows 7. I use a Zend server to develop another 81 (Zend CE) sites on Port 80 (XAMPP). I do not want to use Port 80 on my other virtual servers by using port 81 on another server. Port 80 no. I tried but everyone is getting a request to do a search on Google

    
 I made changes to the host file.   
 
 
 Missing to edit:  
  NameVirtualHost *: 81
