What is Linux server virtualization?

Before into the definition of Linux server virtualization, let us know what virtualization means. In simplest terms, virtualization is the process of creating a computerized version of something physical or tangible. But if we add virtualization with Linux server, this may refer to two things: desktops or personal computers and servers.

When we speak of Desktop or PC Virtualization, it means concealing the resources of desktop, which include operating systems, processors as well as the number and identity of each physical PC machine, from the users. Although it belongs to another form of virtualization, a cloud storage solution saves documents from the computer to an internet-based storage facility.

Meanwhile, Server Virtualization refers to concealing the resources of the server, which consist of operating systems, processors as well as the number and identity of each server hardware, from the users.

The general objective of both virtualizations is to keep the users from having difficulties in understanding and managing the technical aspects of the desktop and the server resources. Furthermore, they also increase the sharing and usage of resources as they maintain the capacity for expansion in the future.

Other Forms of Virtualization

Aside from the aforementioned Linux server virtualization, there are other forms of virtualizations. They are Network and Storage.

*Network Virtualization is the combination of hardware and software resources as well as the functions of networks into a single virtual network. Citrix, OpenSolaris and Vyatta are some examples of this virtualization.

*Storage Virtualization, as what the name implies, produces more advanced data storage capacity of a computer. Most of the time, this refers to saving documents and other important files to an online storage cloud for better and wider keeping virtual vault.

Linux server virtualization Software

Here is some open Linux server virtualization software that you can use.

1. Bochs

In a general sense, this is portable PC debugger and emulator. This can run a number of host OS, including Linux, Mac OS X, Windows and Windows Mobile. Moreover, there is also a number of guest OS that can use this emulator to run the system such as AmigaOS, BSDs, DOS, MorphOS and Rhapsody.

2. Linux-VServer

This is a virtual private server implementation or a vps hosting provider that works by adding the Linux kernel with the capabilities of a functional and operative virtualization system

3. OpenVZ

This is another Linux server virtualization software that is purely based on the kernel and OS of Linux.

4. VirtualBox

It is a software virtualization package that is pioneered by Sun Microsystems. Host operating systems like Linux, Mac OS X, Solaris and Windows XP or Vista support this type of open virtualization. Meanwhile, guest operating systems such as FreeBSD and OpenBSD also support VirtualBox.

5. Xen

A virtual monitor, Xen allows some guest OS to concurrently run on the same computer machine. Apparently, this software is included in some Linux OS subcategories like Debian, CentOS, Fedora, Red Hat Enterprise Linus, Ubuntu, among others.
