Redirect 설정 후 에러..

<VirtualHost www.test.com>             
        ServerAdmin webmaster@test.com        
        DocumentRoot /home/test/public_html
        ServerName www.test.com         
        ErrorLog logs/test-error_log       
</VirtualHost>                               
<VirtualHost test.com>                
        ServerAdmin webmaster@test.com       
        DocumentRoot /home/test/public_html
        ServerName www.test.com        
        ErrorLog logs/test-error_log       
        Redirect / http://www.test.com/
</VirtualHost>

이렇게 redirect 설정후 아파치를 스타트 시키면 Hostname and service name not provided or found : Could not resolve host name test.com -- ignoring!

이라고 에러가 뜨는데 무슨 이유인가요??
