Vps

If you have a dedi, how do you create vps and resellers?

and what is so different between the two and why does a vps cost so much more?

To create a VPS you need some software from a company or something...can't exactly remember. To create resellers all that you need is a control panel like cPanel X.

A VPS costs a lot mroe than a reseller because it comes with root access.

the most used software for VPS on Linux is Virtuozo. Read a few manuals, google this and you'll find a perfect answer ;)
