When virtualization is implemented, several operating systems can run in a single computer all at the same time. This process has become the trend today since it allows maximum usage and leverage on the CPU and the capacity of one’s server system. One advantage of implementing virtualization is while several operating systems stability is assured in your system.  If one guest system crashes, you can be sure that other guest systems and the host system will not crash as well. They can go on running and not get affected by the crash in one system. There’s also no need for to configure a dual boot environment. So if, for instance, one is running Fedora he can try Ubuntu without having to shut down Fedora and boot Fedora. What one merely has to do is just to start up the virtualized Fedora. Fedora virtualization can be taken up in several ways. One can do it through VMware and he can also do it through KVM. Xen is also one of the most popular technologies on Fedora.

A good thing about Fedora is that since it is from Linux so it’s an open-source software. It’s free so one wouldn’t have to buy the software. Simply download Fedora. Of course, one has to shell a minimal amount to get a DVD copy from someone. If virtualization is done using Fedora 7, it would easier since virtualization is already built in with it. This is in contrast to using VMware server which one would have to get separately from the operating server. It’s more convenient and less costly.

Virtualization is basically the abstraction of underlying IT technical details running under an external interface.  In many instances virtualization means having one resource to act and perform like several or multiple resources. It could also be the other way around. Multiple resources could also be pooled together to perform as a single resource.

FreeBSD virtualization is a type of virtualization that occurs on a computer run under a FreeBSD operating system. And since FreeBSD is an operating system, the simulation actually occurs at the operating system level. What typically happens is that the FreeBSD based computer is partitioned into several small systems.

One reason why this is done is to enable several systems to run in parallel without interrupting each other. Like in the case of having several independent IT projects running under one computer, it would be convenient and even imperative that each do not intercept the other. The resources that one computer has is actually compartmentalized so as not to affect the other compartments. It’s done for security reasons and it’s done for an easier management and administration as well.

As each partition is compartmentalized there would be a separate partition or FreeBSD jail for all relevant files, user accounts and processes. In a company IT system, this would secure each partition from any breach since only relevant users can have access to their own files. Management would also be easier. IT personnel handling one compartment would be delegated without being given access and control over the whole system. The check and balance and the security measures are then more secure with such technology and way of virtualization.
