Virtual Machine Manager

The "Virtual Machine Manager" application (virt-manager for short package name) is a desktop user interface for managing virtual machines. It presents a summary view of running domains, their live performance & resource utilization statistics. The detailed view graphs performance & utilization over time. Wizards enable the creation of new domains, and configuration & adjustment of a domain's resource allocation & virtual hardware. An embedded VNC client viewer presents a full graphical console to the guest domain.

Linux kernel

The Linux kernel is an operating system kernel used by a family of Unix-like operating systems. The term Linux distribution is used to refer to the various operating systems that run on top of the Linux Kernel.

The Linux kernel is released under the GNU General Public License version 2 (GPLv2) plus proprietary licenses for some controversial BLOBs and is developed by contributors worldwide; Linux is one of the most prominent examples of Free / Open Source software.

The Linux kernel was initially conceived and created by Finnish software engineer Linus Torvalds in 1991. Early on, the MINIX community contributed code and ideas to the Linux kernel. At the time, the GNU Project had created many of the components required for a free software operating system, but its own kernel, GNU Hurd, was incomplete and unavailable. The BSD operating system had not yet freed itself from legal encumbrances. This meant that despite the limited functionality of the early versions, Linux rapidly accumulated developers and users who adopted code from those projects for use with the new operating system.

What is CentOS? Why should I choose it?

CentOS is a community-supported Linux distribution built off the open-source, free packages prepared for Red Hat Enterprise Linux. CentOS is a free edition of the very same software that makes Red Hat an enterprise Linux solution, without the unnecessary cost of an extra support contract in order to gain access to software updates, technical resources, and new releases, services which we provide to you directly.

CentOS delivers the same access to industry standard software including full compatibility with software packages prepared specifically for Red Hat Enterprise Linux systems. It provides the same level of security support through software updates, product lifetime, and performance of other enterprise Linux solutions.

In addition, each major release exactly coincides with a release of Red Hat's distribution, ensuring that CentOS always provides a consistent compatibility with all software packages released specifically by or for Red Hat.

What is Linux?

The Linux kernel, pronounced 'linnuks' is the heart of the CentOS operating system. A kernel is an important part of any operating system, providing the communication bridge between hardware and software.

Linux was brought to life in 1991 by a Finnish student named Linus Torvalds. At the time, it would run only on i386 systems, and was essentially an independently created clone of the UNIX kernel, intended to take advantage of the then-new i386 architecture.

Nowadays, thanks to a substantial amount of development effort by people all around the world, Linux runs on virtually every modern architecture.

The Linux kernel has gained an ideological importance as well as a technical one. There is an entire community of people who believe in the ideals of free software and spend their time helping to make open source technology as good as it can be.

People in this community gave rise to initiatives such as CentOS, standards committees that shape the development of the Internet, organizations like the Mozilla Foundation, responsible for creating Mozilla Firefox, and countless other software projects from which you've certainly benefited in the past.

The spirit of open source, commonly attributed to Linux, is influencing software developers and users everywhere to drive communities with common goals.

What is GNU?

The GNU Project, pronounced “guh-noo”, was launched in 1984 to develop a complete UNIX style operating system which is comprised of free software: the GNU system. Variants of the GNU operating system, which use the Linux kernel, are now widely used.

The GNU project is closely linked to the philosophy of free software, which is central to the projects that derive from it, such as CentOS.
