What is a server virtualization?  Are there any other good approaches to define server virtualization?  What are the essential facets to consider when you try to engage in virtualization of your server?

Server Virtualization is the hiding the resources of the servers – which includes the exact server numbers, the processors that are working with the server, the operating systems used by each server, and the peripheral devices connected to the server – away from the users of the server. The server manager usually performs the hiding by employing a third party application software to chop and divide a single physical server into many other servers under a virtual situation or environment.  The working virtual environment is often referred to as the private virtual servers.  In some other instances, the private virtual servers are commonly referred to as the partition or the guest.

Server virtualization is easily understood when it is being learned under these approaches:  the virtual machine or the VM model, the more concrete paravirtual or the PVM model, and lastly the virtualization of the server in the operating systems layer or the OS level. 

The virtual server machine is set-up under the paradigm of host and guest.  One server should act as the host or the main server where the guest servers would emanate.  This kind of server virtualization allows for the guest OS to run and execute without any other modifications made on it.  In addition, it allows for the server manager to make and create other guest servers that will allow for the usage of varied and different operating systems on it.
