<VirtualHost *:80>
    ServerAdmin me@grussell.org
    DocumentRoot /home/dave/public_html/web
    ServerName web-5-97.linuxzoo.net
    ErrorLog logs/sql-error_log
    CustomLog logs/sql-access_log common
</VirtualHost>

<VirtualHost *:80>
    ServerAdmin me@grussell.org
    DocumentRoot /home/dave/public_html/vm
    ServerName vm-5-97.linuxzoo.net
    ErrorLog logs/sql-error_log
    CustomLog logs/sql-access_log common
</VirtualHost>
