It's possible to run some web servers in some systems in virtual networks with virtualization, however, opening to the public all of web servers are not so easy because some global IP address is also needed, but getting some global IP address takes many costs. Therefore, it becomes neccessary to use the function of virtual hostings which Apache has.
Well, here is the example to configure virtual hostings. Following example is done as domain name[server-linux.info (root directory[/var/www/html])], virtual domain name[virtual.info (root directory[/home/fedora/public_html])].
[1] Add virtual domain name in DNS first.

[root@ns ~]# vi /etc/named.conf
// add them in 'view "internal"' section
zone "virtual.info" IN {
type master;
file "virtual.info.lan";
allow-update { none; };
};
// add them in 'view "external"' section
zone "virtual.info" IN {
type master;
file "virtual.info.wan";
allow-update { none; };
};
[root@ns ~]# cp /var/named/server-linux.info.lan /var/named/virtual.info.lan
[root@ns ~]# cp /var/named/server-linux.info.wan /var/named/virtual.info.wan
[root@ns ~]# vi /var/named/virtual.info.lan
