How to define several VirtualHost with apache 2 and ubuntu 10.4?

[sedigh mohseni]

hi
I'd like to define virtual host for testing my site locally
i put folders of my sites with name byttes and dms in /home/sepideh/www/ path.
Then i change file in path /etc/apache2/sites-enables/000-default and i add below lines

<VirtualHost>
ServerRoot /home/sepideh/www/byttes
ServerName byttes.ir
ServerAlias byttes.ir
</VirtualHost>
 
<VirtualHost>
ServerRoot /home/sepideh/www/dms
ServerName dms.com
ServerAlias dms.com
</VirtualHost>
 

too, i change hosts file in path /etc/hosts
and i add 127.0.0.1 byttes.ir
127.0.0.1 dms.com
and the restart apache via /etc/init.d/apache2 restart
but i unfortunately see below error with restart apache
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
... waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
[ OK ]


with typing byttes.ir or dms.com in the browser url i see below content

Not Found

The requested URL / was not found on this server.
Apache/2.2.14 (Ubuntu) Server at dms.com Port 80

i found problem i wrote ServerRoot instead of DocumentRoot
with this change i answer correctly but i still get the same final error about apache that is as follow as

apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
... waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
[ OK ]
