The Open Virtualization Alliance (OVA) was a Linux Foundation Collaborative Project committed to foster the adoption of free and open-source software virtualization solutions including KVM, but also software to manage such, e.g. oVirt. The consortium promoted examples of customer successes, encouraged interoperability and accelerated the expansion of the ecosystem of third party solutions around KVM. [1]

The OVA provided education, best practices and technical advice to help businesses understand and evaluate their virtualization options. The consortium complemented the existing open source communities managing the development of the KVM hypervisor and associated management capabilities, which are rapidly driving technology innovations for customers virtualizing both Linux and Windows® applications. The OVA was not a formal standards body and did not influence upstream development, but encouraged interoperability and the development of common interfaces and application programming interfaces (APIs) to ease the adoption of KVM for users.

On 21 October 2013, it was announced that the Open Virtualization Alliance will become a Linux Foundation Collaborative Project. [2]

Having achieved its original purpose, on 1 December 2016, the OVA was officially dissolved.

Software promoted by OVA

Membership

Initially formed by Red Hat and IBM, [3] the Alliance had over 200 members involved with enterprise virtualization. [4] Participation was open and the OVA encouraged new participants to become members. Membership was tiered, with governing memberships requiring higher dues than general memberships. One of the criteria for joining the Alliance was to produce or use a product or service that is based on KVM.

A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the same kernel.

In computing, paravirtualization or para-virtualization is a virtualization technique that presents a software interface to the virtual machines which is similar, yet not identical, to the underlying hardware–software interface.

virt-manager Virtualisation software

virt-manager is a desktop virtual machine monitor primarily developed by Red Hat.

The following is a timeline of virtualization development. In computing, virtualization is the use of a computer to simulate another computer. Through virtualization, a host simulates a guest by exposing virtual hardware devices, which may be done through software or by allowing access to a physical device connected to the machine.

Oracle Linux is a Linux distribution packaged and freely distributed by Oracle, available partially under the GNU General Public License since late 2006. It is compiled from Red Hat Enterprise Linux (RHEL) source code, replacing Red Hat branding with Oracle's. It is also used by Oracle Cloud and Oracle Engineered Systems such as Oracle Exadata and others.

<span class="mw-page-title-main">Kernel-based Virtual Machine</span> Virtualization module in the Linux kernel

Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the 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.

Hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems. Virtualization hides the physical characteristics of a computing platform from the users, presenting instead an abstract computing platform. At its origins, the software that controlled virtualization was called a "control program", but the terms "hypervisor" or "virtual machine monitor" became preferred over time.

Infrastructure as a service (IaaS) is a cloud computing service model by means of which computing resources are supplied by a cloud services provider. The IaaS vendor provides the storage, network, servers, and virtualization. This service enables users to free themselves from maintaining an on-premises data center. The IaaS provider is hosting these resources in either the public cloud, the private cloud, or the hybrid cloud.

oVirt Free, open-source virtualization management platform

oVirt is a free, open-source virtualization management platform. It was founded by Red Hat as a community project on which Red Hat Virtualization is based. It allows centralized management of virtual machines, compute, storage and networking resources, from an easy-to-use web-based front-end with platform independent access. KVM on x86-64, PowerPC64 and s390x architecture are the only hypervisors supported, but there is an ongoing effort to support ARM architecture in a future releases.

libvirt Management tool

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.
