Webmin is a web-based interface for system administration for Linux computers. Managing a VirtualBox VDI with WebMin is simple and makes managing servers child's play.
Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.
