This document provides information about getting started with using XenServer and OpenStack. It discusses:
1. Why Xen was built for cloud computing and its history and community support.
2. How to install Xen Cloud Platform or Citrix XenServer and then install OpenStack on top as a domU virtual machine to manage the Xen hypervisor.
3. Tips for configuring the XenAPI driver and networking when first getting started with OpenStack on XenServer.
Rackspace has years of experience with running Xen at scale, starting with Xen and migrating to XenServer. We will share why we use Xen/XenServer along with some of the issues that we've experienced. We will touch on our experience with migrating from Xen to XenServer and the challenges there. We will share information about Rackspace Cloud Servers architecture, and touch briefly on OpenStack when doing so. We will explain how we use Xen to quickly deploy new Openstack services with what we call Nova on Nova. And finally, we will discuss what additional features and improvements are needed and why.
Cloud leaders such as Rackspace and Internap are building their next generation cloud using OpenStack and Xen+XenAPI, not everyone uses OpenStack with KVM. Lets take a look at how OpenStack and Xen work together, and look at how you can get more involved.
It is no accident that Xen software powers some of the largest Clouds in existence. From its outset, the Xen Project was intended to enable what we now call Cloud Computing. This session will explore how the Xen Architecture addresses the needs of the Cloud in ways which facilitate security, throughput, and agility. It will also cover some of the hot new developments of the Xen Project.
Xen, XenServer, and XAPI: What’s the Difference?-XPUS13 Bulpin,PavlicekThe Linux Foundation
Many people have difficulty understanding the difference between the Xen Hypervisor, XenServer, and XAPI. In this session, James Bulpin, Director of Technology for XenServer, and Russell Pavlicek, Evangelist for the Xen Project, will attempt to clarify what each project is, what it does, and how it compares with the others. We will cover some of the basic features and functions, the tasks for which each is suitable, and where the projects overlap. Attendees will come away with a better sense of where these three projects fit in the world of Xen virtualization.

Oscon 2012 : From Datacenter to the Cloud - Featuring Xen and XCPThe Linux Foundation
Do you dream of being able to spin up ten or twenty (or a thousand) virtual machines in an instant? Discover and repair resource bottlenecks without moving a finger? Dodge the loss of an entire storage array with no-one noticing? Span across data centers with a fleet of virtual machines? This is no sales pitch; during this tutorial, we’ll demonstrate how to leverage truly FOSS tools to build a powerful, scalable cloud that easily competes with those proprietary solutions!
This deep-dive into Xen, Xen Cloud Platform, and other FOSS cloud tools and concepts is intended both for those ready to wholeheartedly embrace virtualization and for those already seasoned in general virtualization practices. You’ll leave with a collection of pre-made tools that you can use right out of the box or modify to your liking. You’ll also leave with immediately useful knowledge on best practices and common pitfalls, presented by actual FOSS practitioners like you.
We begin this tutorial by discussing Xen, Xen Cloud Platform (XCP), and XCP cloud concepts (pools, hosts, storage, networks, etc.). We then explore in detail the API that makes Xen so useful for building a cloud, explore provisioning of hosts and guests using PXE, and discuss templating and installing guest virtual machines. Critical to understanding potential bottlenecks, identifying tuning opportunities and planning for the future, we will discuss performance monitoring and methodologies. Next, we teach you how to make the most of your new FOSS cloud capabilities and discuss in detail high availability infrastructure for storage and networking, advanced networking capabilities like bonding/VLANs, and the cloud orchestration tools that save you time and money. All of this with a focus on XCP in enterprise environments. Tools discussed include DRBD, Pacemaker, Open vSwitch, Cloudstack, Openstack, and more.
We conclude by shedding light on exciting developments: Xen 4.2 has recently been released, with just over a year of development time and nearly 3,000 changesets. We will discuss many of the new features introduced in 4.2, as well as what changes we have in store for the 4.3 release as well as other exciting developments.
The Xen Hypervisor was built for the Cloud from the outset: when Xen was designed, we anticipated a world, which today is known as cloud computing. Today, Xen powers the largest clouds in production.
This talk explores success criteria, architecture, trade-offs and challenges for cloudy hypervisors. It is intended for users and developers and starts with a brief introduction to Xen and XCP, their architecture and on common challenges for KVM and Xen.
I will introduce the concept of domain disaggregation as an approach to increase security, robustness and scalability: all important factors for building clouds at scale and show how advanced security features suchas Xen Security Modules and SELinux can help secure your cloud further.
The talk will conclude with exciting developments in the Xen community, such as Xen for ARM servers, a new virtualization mode for Xen, running applications without OS in a Xen guest and point out their implications for building open source clouds.
LCEU13: Securing your cloud with Xen's advanced security features - George Du...The Linux Foundation
Xen is a mature enterprise-grade virtual machine with many advanced security features which are unique to Xen. For this reason it's the hypervisor of choice for the NSA, the DoD, and the new QubesOS Secure Desktop project. While much of the security of Xen is inherent in its design, many of the advanced security features, such as stub domains, driver domains, XSM, and so on are not enabled by default. This session will describe all of the advanced security features of Xen, and the best way to configure them for the Cloud environment. When the audience leaves, they should have a general framework to evaluate the security of their system, know the key security features of Xen, and have a basic framework of knowledge to help them make sense of the documentation. This talk will *not* go into mind-numbing detail about specific commands to type or configuration options.
Google uses virtualization for internal corporate infrastructure. As part of this, we have developed a number of tools, some open source, for managing the Xen deployment. The talk will describe the technical infrastructure used, the internal workflows and machine management processes, and the specific use-cases for virtualization.
Nowadays there is significant diversity in Infrastructure
as a Service (IaaS) clouds. The differences span from
virtualization technology and hypervisors, through storage
and network configuration, to the cloud management
APIs. These differences make migration of a VM (or
a set of VMs) from a private cloud into a public cloud,
or between different public clouds, complicated or even
impractical for many use-cases.
HVX is a virtualization platform that enables complete
abstraction of underlying cloud infrastructure from the
application virtual machines. HVX allows deployment
of existing VMs into the cloud without any modifications,
mobility between the clouds and easy duplication
of the entire deployment.
HVX can be deployed on almost any existing IaaS
cloud. Each instance of the HVX deployment packs in
a nested hypervisor, virtual hardware, network and storage
configuration.
Combined with image store and management APIs,
the HVX can be used for the creation of a virtual cloud
that utilizes existing cloud provider infrastructure as the
hardware rather than using physical servers, switches and
storage.
CloudStack, the world's leading open-source cloud infrastructure platform, was recently donated to the Apache Foundation, and is now an incubated Apache project. Ewan Mellor, Director of Engineering in the Citrix Cloud Platforms Group will describe the CloudStack project and explain why Xen is the pre-eminent hypervisor in public clouds today. He will describe the changes coming in CloudStack in the next 12 months, and how they are going to change the way that Xen is consumed in public and private clouds next year.
Hypervisor Capabilities in Apache CloudStack 4.3Tim Mackey
Apache CloudStack 4.3 adds support for clouds built using Microsoft Hyper-V, in addition to supporting VMware vSphere, Citrix XenServer, KVM, Oracle VM, Linux Containers and bare metal options. This deck covers the decision points impacting the design of CloudStack 4.3 clouds, and their relationship with hypervisor choices.
Presented at Build a Cloud Day co-located with SCaLE 12x in February 2014.
Hypervisor Selection in Apache CloudStack 4.4Tim Mackey
Building an infrastructure as a service cloud involves a number of technology decisions, many of which could have unforeseen impact. Hypervisors form the core of an IaaS cloud, and whether you are a fan of Microsoft Hyper-V, VMware vSphere, KVM in any Linux variant or XenServer from Citrix, each of these hypervisors provide unique capabilities within an Apache CloudStack 4.4 based cloud.
Linaro Connect Asia 13 : Citrix - Xen on ARM plenary sessionThe Linux Foundation
The Xen on ARM effort has had a short, but impressive, history. In late 2011, Citrix seeded a Xen.org community project to port Xen to ARMv7 with virtualization extensions targeting the Cortex A15 as the reference platform. In 2012, the project scope was expanded to include the ARMv8 architecture. Linux 3.7 was the first kernel release to run on Xen on ARM as Dom0 and DomU. Very soon now (Q2 2013), Xen 4.3 will fully support several different ARM platforms, including Samsung Chromebooks, Versatile Express Cortex A15 and Arndale development boards.
In this talk, we will outline how virtualization enabled server consolidation and cloud computing, as well as innovative and secure solutions for both desktops and mobile devices. We will explain why Citrix saw the need for the project, and why it is highly relevant in today’s cloud-centric virtualization landscape. We will discuss the opportunities this has brought to the Xen ecosystem, and then peek into the future possibilities which Xen on ARM will enable. While Xen is best known as technology powering some of the biggest clouds in the industry, but could also be powering virtual machines on devices that fit in your pocket.
The talk will also include a brief overview of the Xen on ARM architecture, including the key design principles employed. The techniques pioneered during the ARM port will allow the Xen community to remove many legacy components from the Xen code base, streamlining both the ARM and x86 implementations. We will share some data on the challenges in porting Xen to new ARM boards. Due to full reliance on Device Tree and to the minimal hardware requirements of the hypervisor, ports to new boards require surprisingly little effort.
Finally, the talk will conclude by outlining the immediate roadmap for Xen on ARM.
RBD, the RADOS Block Device in Ceph, gives you virtually unlimited scalability (without downtime), high performance, intelligent balancing and self-healing capabilities that traditional SANs can't provide. Ceph achieves this higher throughput through a unique system of placing objects across multiple nodes, and adaptive load balancing that replicates frequently accessed objects over more nodes. This talk will give a brief overview of the Ceph architecture, current integration with Apache CloudStack, and recent advancements with Xen and blktap2.
CloudStack is one of many cloud orchestration platforms which can deliver IaaS clouds. One of the key capabilities of CloudStack is its ability to support multiple hypervisors in a CloudStack cloud. So whether your virtualization preference is VMware vSphere, KVM, Citrix XenServer or Linux Containers (LXC), you can build highly scalable clouds. While basic functionality is common across all hypervisors, many features are implemented differently on each. This paper presents the capabilities of CloudStack which can be enabled based on your hypervisor selection
The Xen 4.3 release we will experiment with a roadmap: an informal set of features and changes that we as a community will be aiming at for the 4.3 release. The roadmap is flexible, but will be used as a guide to coordinate our efforts, as well as a benchmark to let us know when 4.3 will be ready to release.

Ravello webinar - Creating smart labs on AWS/Google for sales demos, training...shrutib
This webinar will cover the concept of Smart Labs that let you spin up your application in as many cloud-based lab environments as you need, without any migration overhead.
Once upon a time - not too long ago - setting up repeatable application environments with complex networking, multiple VMs took days or even weeks and capacity planning was a nightmare. Today, you can automatically spin up complex environments in leading public clouds and run any VMs - including existing VMware/KVM virtual machines, and virtual appliances such as Cisco, Brocade, Juniper, F5, Check Point, Infoblox and any networking - including static IPs, multiple subnets, broadcast and multicast.
We will discuss and demonstrate live how Ravello’s Smart Labs on AWS or Google Cloud, powered by nested virtualization and software defined networking, let you:
1. Provision hundreds of student environments with one click or API call for virtual training or classrooms - and pay only for usage
2. Enable sales teams with live cloud-based demo environments for your application software that they can deploy & destroy as needed from anywhere in the world
3. Ensure that QA teams never have to wait for test environments for automated testing

6. Why use Xen today?
• Open Source with a large community and ecosystem
• Mature and “Cloud Proven”
ᵒAmazon, Rackspace and many others
• Probably 10-12 Million OpenSource Users
ᵒe.g. 3 x people on Debian have used Xen in the last 30 days vs KVM
ᵒ12% of Ubuntu Servers hosted on Xen
• Type 1 hypervisor
ᵒReduced TCB
ᵒBest security, isolation, performance, scalability mix
• ParaVirtual OPerationS now in Linux
12. How can I install it?
Xen Cloud Platform (XCP) Citrix XenServer
• Includes Xen and XAPI • Includes Xen and XAPI
• Supported by Xen Community • Fully Supported by Citrix
• Fully OpenSource • Free edition
• xcp-xapi package ᵒWindows VMs
ᵒPool based Live Migration
ᵒDebian Wheezy & Ubuntu Precise
ᵒHopefully in Fedora soon

32. Intro to Cloud Servers
Overview
• Public Cloud product under Rackspace‟s Open Cloud portfolio
• First Gen
– Code originated from Slicehost acquisition
– Initially Xen 3.x, but migrated to XenServer
• Next Gen
– Public Launch 8/1/2012
– Powered by OpenStack
• XenServer 6
• Linux, Windows, and FreeBSD VMs

33. Intro to Cloud Servers
Statistics
• 180,000+ total Rackspace customers (not just Cloud Servers)
• Tens of thousands of hosts
• Hundreds of thousands of VMs
• Millions of snapshots

35. Why Xen?
• Thin hypervisor layer
• Open source
• Excellent driver support due to Linux dom0
• Good API
• Good performance
• Along with Linux, Windows VMs are a must
– Same virtualization technology desired for Windows
– Microsoft will support
– Good PV driver support

36. OpenStack
nova-compute w/ XenAPI
• Runs in a utility domU on each host
• Images downloaded in dom0 Physical host running XenServer
– glance XenAPI plugin
• Images attached to nova-compute domU dom0 nova utility domU
– Partitioning changes glance plugin nova-compute
– file-system resizing
• Monitors VMs‟ power_state
agent plugin
• Snapshots/backups xenstore plugin nova instance
• VM resize/migration domUs
– rsync to new host
• Communicates w/ agent inside VMs
– Via xenstore

38. OpenStack Rackspace Specifics
Source Code
• Rackspace tracks trunk
– Deployed code generally less than 2 weeks behind trunk
• Some custom patches on top of trunk
– Features specific to Rackspace
– Custom scheduling to meet Rackspace needs
– Scaling with OpenStack Compute Cells

39. Deploying OpenStack
„Inception‟
• Private internal cloud
– Based on Openstack, called iNova
– OpenStack services for public cloud run virtualized under iNova
• Easy to spin up additional services for load balancing
– Enables quick reaction to load spikes
• Easier deployments of new compute cells
• Automated reaction to downed hosts
• Enables new strategies for deployments
– Replace vs Upgrade

41. Deploying OpenStack
Continuous Deployment
• Trunk and custom branches merged multiple times daily
– Unit Tested and Packaged
• Configuration managed with puppet
– Follows same QE and Continuous Deployment rules as code
• QE Environment
– OpenStack control infrastructure deployed on iNova
– nova-compute upgraded on 200 hosts
– Smoke tests
• Staging Deploy
– Uses the same packages and puppet manifests

Lets look at how an image is launched in OpenStack
Been using Xen since before KVM was an option.
Rackspace specific features mostly means features the community doesn’t care about or features that are just not appropriate for the community.
