Xen - Open Source Virtualization

  •        0

The Xen hypervisor is a layer of software running directly on computer hardware replacing the operating system thereby allowing the computer hardware to run multiple guest operating systems concurrently. It suppors x86, x86-64, Itanium, Power PC, and ARM processors allow the Xen hypervisor to run on a wide variety of computing devices.

With Xen virtualization, a thin software layer known as the Xen hypervisor is inserted between the server's hardware and the operating system. This provides an abstraction layer that allows each physical server to run one or more "virtual servers", effectively decoupling the operating system and its applications from the underlying physical server.

Libvirt - The virtualization API

Libvirt is collection of software that provides a convenient way to manage virtual machines and other virtualization functionality, such as storage and network interface management. These software pieces include an API library, a daemon (libvirtd), and a command line utility (virsh). It provides a single way to manage multiple different virtualization providers/hypervisors like Xen, OpenVZ, VirualBox, Microsoft Hyper-V hypervisor, VMware.

QEMU - Machine Emulator and Virtualizer

QEMU is a generic and open source machine emulator and virtualizer. When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance.

VirtualBox - Cross-Platform Virtualization Application

VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. VirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems. So, for example, you can run Windows and Linux on your Mac. VirtualBox is a so-called hosted hypervisor. It requires an existing operating system to be installed. It can thus run alongside existing applications on that host.

Proxmox - Virtualization Platform

Proxmox Virtual Environment is a powerful Open Source Server Virtualization Platform, based on KVM and OpenVZ. It gives you near-bare-metal performance and leading scalability for your workloads. You can virtualize even the most demanding application workloads. It supports 32 bit and 64 bit Windows and Linux servers.

Archipel - Virtual Machine Orchestration

Archipel is a solution to manage and supervise virtual machines. No matter if you have a few locally on your computer or thousands through data centers, Archipel is a central solution to manage them all. You can perform all basic virtualization commands and many other things like live migration, VMCasts, packages, etc. Use it with KVM, Xen, OpenVZ, VirtualBox, and mix them all if you want to.

Spice - Solution for interaction with Virtualized Desktop Devices

The Spice project aims to provide a complete open source solution for interaction with virtualized desktop devices. Its main focus is to provide high-quality remote access to QEMU virtual machine. Seeking to help break down the barriers to virtualization adoption by overcoming traditional desktop virtualization challenges, emphasizing user experience. For this purpose, Red Hat introduced the SPICE remote computing protocol that is used for Spice client-server communication.

Open vSwitch - Multilayer Virtual Switch

Open vSwitch is well suited to function as a virtual switch in VM environments. In addition to exposing standard control and visibility interfaces to the virtual networking layer, it was designed to support distribution across multiple physical servers. Open vSwitch supports multiple Linux-based virtualization technologies including Xen/XenServer, KVM, and VirtualBox.

nova-powervm - PowerVM virtualization driver for OpenStack Nova

The IBM PowerVM hypervisor provides virtualization on POWER hardware. PowerVM admins can see benefits in their environments by making use of OpenStack. This driver (along with a Neutron ML2 compatible agent and Ceilometer agent) provides the capability for operators of PowerVM to use OpenStack natively.As ecosystems continue to evolve around the POWER platform, a single OpenStack driver does not meet all of the needs for the various hypervisors. The standard libvirt driver provides support for KVM on POWER systems. This nova driver provides PowerVM support to OpenStack environment.

ceilometer-powervm - PowerVM compute agent plugins for OpenStack Ceilometer

The IBM PowerVM hypervisor provides virtualization on POWER hardware. PowerVM customers can see benefits in their environments by making use of OpenStack. This project implements a Ceilometer-compatible compute inspector. This inspector, along with the PowerVM Nova driver and Neutron agent, provides capability for PowerVM customers to natively monitor utilization and statistics for instances running on OpenStack-managed systems.PowerVM supports a variety of performance monitoring interfaces within the platform, providing virtual machine and system monitoring data. Ceilometer-powervm implements a Ceilometer-based compute inspector for the PowerVM hypervisor.
