The Bare-Metal Hypervisor as a Platform for Innovation

In this industry, everyone seems to talk about innovation, but very few platforms exist which foster innovation.  More times than not, “innovation” is simply a buzzword used by some marketing campaign to hawk something about as novel as twenty-year-old accounting software.

Innovation does occur, of course.  But often real innovation leverages what already exists to create something which doesn’t yet exist.  It may borrow from the known, but it produces something previously unknown.  For example, the industry has been going wild over cloud computing in the past few years, but many of the core cloud computing concept are actually old mainframe concepts reimagined in the world of commodity servers.

Making a Place for Innovation to Thrive

A bare-metal hypervisor — like the one produced by the Xen Project — can be an excellent platform for innovation.  We think of hypervisors as old technology, plumbing for newer technologies like cloud — and, indeed, they are.  But the nature of the bare-metal hypervisor makes it an excellent platform for innovation to take place.

Using Xen Project on OpenStack “Juno” via Libvirt

By Xing Lin

This document describes steps I took to setup a compute node based on Ubuntu 14.04 for OpenStack “juno”, using the Xen Project via libvirt approach. Openstack does not support this approach well as it is in Group C of the hypervisor support matrix for Openstack. You can hardly find any tutorial online describing this approach and this might be the first. Let’s get started!

Prerequisites

Follow “OpenStack Installation Guide for Ubuntu 14.04″ to setup the control node and network node, following the three-node architecture with OpenStack Networking (neutron). This involves lots of configuration and could take a day or two. Check that the control node and network node is working.

History of Xen – Architecture

As I continue to learn more about Xen, I find it interesting to read old documents that show the transformation of Xen from a research project at Cambridge University to the current leading open source hypervisor technology. A great link form Cambridge University is available with a collection of documents and presentations. I would like to highlight two documents that I found worth reading:
