How to Make a VPS on a Dedicated Server?
A dedicated server is a set of hardware rented by one customer for his exclusive disposal and not shared with anyone else. A VPS (or VDS) is a virtualized machine, which emulates a real server utilizing only a portion of hardware. VDS users obtain superuser rights and can configure their machines the way they like. One physical computer can be divided into multiple virtualized ones by means of specialized virtualization technique.
Why create a VPS on a dedicated server?
Sooner or later, most of VPS clients need their current machines to be upgraded with more RAM volume, higher processor parameters, etc. At the same time, they would like the administration process to remain as easy as it is. In this case, a real server with a virtualized machine installed looks like an attractive option for such customers. It is also an optimal choice for those who need several virtual machines on the same piece of hardware. Running a few VPSs on one machine is more cost-efficient than renting a number of virtual servers separately.

To transform a real server into a VPS, one has to perform the actions listed below:
- Make sure the computer you are installing a VDS on complies with the hypervisor demands. The latter (also called a virtual machine monitor or VMM) is a software suite purposed for creating virtualized machines on a real server. VMM is only compatible with particular characteristics of hardware.
- Save the essential data and current settings on your physical machine.
- Install the hypervisor software from an installation disc.
- Open the console and create a virtual machine. In some hypervisors, you can choose memory space and processor performance needed. The hypervisor user manual will lead you through the whole sequence.
- Install an operating system from a disk image.
- Configure and set up the appliance.
- Repeat the whole sequence for all the appliances you are going to install.
One more piece of advice: in case you virtualize a few similar servers, you can copy VPS from server to server, without stopping any programs.
