Open Virtualization Alliance

Open Virtualization Alliance is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Open Virtualization Alliance rather than just read about it. In short: 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.

Key takeaways

Open Virtualization Alliance belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Open Virtualization Alliance to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Open Virtualization Alliance from memory before moving on to harder problems.

Reference excerpt

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

Software promoted by OVA Kernel-based Virtual Machine (KVM) – software that turns the Linux kernel into a hypervisor libvirt – API and its implementation to manage KVM and other virtualization solutions OVirt – web application for managing KVM libguestfs – API and its implementation for modifying virtual disk images

Membership Initially formed by Red Hat and IBM, the Alliance had over 200 members involved with enterprise virtualization. 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.

Worked examples

Example 1 — a first encounter with Open Virtualization Alliance

Start with the simplest possible case. Write down what Open Virtualization Alliance claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Open Virtualization Alliance before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Open Virtualization Alliance ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Open Virtualization Alliance

In research: Open Virtualization Alliance appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Open Virtualization Alliance in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Open Virtualization Alliance is common in secondary-school and first-year university syllabi. It links to neighbouring topics Linux Foundation projects, Virtualization, so understanding it makes those chapters shorter.
In everyday life: Look for Open Virtualization Alliance outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Open Virtualization Alliance in simple terms?

Why does Open Virtualization Alliance matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Open Virtualization Alliance?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
