Ubuntu JeOS
Ubuntu JeOS (pronounced "juice") is a discontinued variant of Ubuntu (operating system), Ubuntu that is described as "an efficient variant ... configured specifically for virtual appliances." It is a concept for what an operating system should look like in the context of a virtual appliance. JeOS stands for "Just enough operating system, Operating System." JeOS has been replaced by Ubuntu Core, which is now an officially supported minimal variant of Ubuntu. Its first release was Ubuntu JeOS 7.10, and since the release of Ubuntu 8.10 it has been included as an option as part of the standard Ubuntu Server Edition. Supported platforms The latest version of JeOS is optimized for virtualization technologies by VMware, VMware, Inc. and the Linux Kernel-based Virtual Machine. Specifications Specifications for version 8.10 and above include: * Part of the standard Ubuntu Server ISO image * Less than 380 MB installed footprint * Specialized server kernel * Intended for VMware ES ...

Linux Kernel
The Linux kernel is a Free and open-source software, free and open source Unix-like kernel (operating system), kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free software, free replacement for Unix. Since the late 1990s, it has been included in many Linux distributions, operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android (operating system), Android which is used in many mobile and embedded devices. Most of the kernel code is written in C (programming language), C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly language, assembly code for architecture-specific logic such as optimizing memory use and task execution. The kernel has a Modular programming, modular design such that modules can be inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

List Of Ubuntu-based Distributions
This page provides general information about notable Linux distributions in the form of a categorized list. Distributions are organized into sections by the major distribution or package management system they are based on. Debian-based Debian (a portmanteau of the names "Deb" and "Ian") Linux is a distribution that emphasizes free software. It supports many hardware platforms. Debian and distributions based on it use the .deb package format and the dpkg package manager and its frontends (such as apt or synaptic). Ubuntu-based Ubuntu (named after the Nguni philosophy of ''ubuntu'') is a distribution based on Debian, designed to have regular releases, a consistent user experience and commercial support on both desktops and servers. Current official derivatives These Ubuntu variants, also known as Ubuntu flavours, simply install a set of packages different from the original Ubuntu, but since they draw additional packages and updates from the same repositories as Ubuntu, ...

OpenSolaris JeOS
OpenSolaris () is a discontinued open-source computer operating system for SPARC and x86 based systems, created by Sun Microsystems and based on Solaris. Its development began in the mid 2000s and ended in 2010. OpenSolaris was developed as a combination of several software ''consolidations'' that were open sourced starting with Solaris 10. It includes a variety of free software, including popular desktop and server software. It is a descendant of the UNIX System V Release 4 (SVR4) code base developed by Sun and AT&T in the late 1980s and is the only version of the System V variant of UNIX available as open source. After Oracle's acquisition of Sun Microsystems in 2010, Oracle discontinued development of OpenSolaris in house, pivoting to focus exclusively on the development of the proprietary Solaris Express (now Oracle Solaris). Prior to Oracle's close-sourcing Solaris, a group of former OpenSolaris developers began efforts to fork the core software under the name OpenIn ...

Libvirt
libvirt is an open-source API, daemon and management tool for managing platform virtualization. It can be used to manage KVM, Xen, VMware ESXi, QEMU and other virtualization technologies. These APIs are widely used in the orchestration layer of hypervisors in the development of a cloud-based solution. Internals libvirt is a C library with bindings in other languages, notably in Python, Perl, OCaml, Ruby, Java, JavaScript (via Node.js) and PHP. libvirt for these programming languages is composed of wrappers around another class/package called libvirtmod. libvirtmod's implementation is closely associated with its counterpart in C/C++ in syntax and functionality. Supported Hypervisors * LXC – lightweight Linux container system * OpenVZ – lightweight Linux container system * Kernel-based Virtual Machine/QEMU (KVM) – open-source hypervisor for Linux and SmartOS * Xen – bare-metal hypervisor * User-mode Linux (UML) – paravirtualized kernel * VirtualBox – hypervis ...

VMware Server
VMware Server (formerly VMware GSX Server) is a discontinued free-of-charge virtualization-software server suite developed and supplied by VMware, Inc. VMware Server has fewer features than VMware ESX, software available for purchase, but can create, edit, and play virtual machines. It uses a client–server model, allowing remote access to virtual machines, at the cost of some graphical performance (and 3D support). It can run virtual machines created by other VMware products and by Microsoft Virtual PC. VMware Server can preserve and revert to a single snapshot copy of each separate virtual machine within the VMware Server environment. The software does not have a specific interface for cloning virtual machines, unlike VMware Workstation. VMware Server has largely been replaced by the "Shared Virtual Machines" feature, introduced in VMware Workstation 8.0 and onwards. Naming The former name ''GSX Server'' allegedly stands for ''Ground Storm X'', an early code name for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

VMware ESX
VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel. After version 4.1 (released in 2010), VMware renamed ESX to ''ESXi''. ESXi replaces Service Console (a rudimentary operating system) with a more closely integrated OS. ESX/ESXi is the primary component in the VMware Infrastructure software suite. The name ''ESX'' originated as an abbreviation of Elastic Sky X. In September 2004, the replacement for ESX was internally called ''VMvisor'', but later changed to ESXi (as the "i" in ESXi stood for "integrated"). Architecture ESX runs on bare metal (without running an operating system) unlike other VMware products. It includes its own kernel. In the historic VMware ESX, a Linux kernel was star ...

Kernel-based Virtual Machine
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the Kernel (operating system), kernel to function as a hypervisor. It was merged into the Mainline Linux, mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules. KVM was originally designed for x86 processors but has since been porting, ported to IBM ESA/390, ESA/390, PowerPC, IA-64, and ARM architecture, ARM. The IA-64 port was removed in 2014. KVM supports hardware-assisted virtualization for a wide variety of guest operating systems including BSD, Solaris (operating system), Solaris, Microsoft Windows, Windows, Haiku (operating system), Haiku, ReactOS, Plan 9 from Bell Labs, Plan 9, AROS Research Operating System, AROS, macOS, ...

Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

JeOS
Just enough operating system (JeOS, pronounced "juice" according to SUSE S.A., SUSE) is a paradigm for customizing operating systems to fit the needs of a particular application such as for a software appliance. The platform only includes the operating system components required to support a particular application and any other third-party components contained in the appliance (e.g., the kernel (operating system), kernel). This makes the appliance smaller, faster (to boot and to execute the particular application) and potentially more secure than an application running under a full general-purpose OS. Common implementations Typically, a JeOS will consist of the following: * JeOS media (OS core [kernel, virtual drives, login]) * OS minimum maintenance tools * Minimum user space tools * Packages repository (DVD or network-based) It is important to differentiate between true fully ''minimalized OS'' install profiles forced, for example, with security hardening tools or representing ...
