Nested Virtualization Update from Intel
Nested Virtualization Update from IntelThe Linux Foundation Nested Virtualization is becoming hot and required to support multiple emerging usage models like XenClient, McAFee Deep Safe, HyperV etc. After enabling nested VMX support for Xen, we have been working on improving its quality and performance to make it run well with these new usages. In the session, we would like update current status of nested virtualization support in Xen, and also demonstrate what we are doing along with new hardware-assisted nested virtulization in this area.
Xen 4.3 Roadmap
Xen 4.3 RoadmapThe Linux Foundation 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.
Openvz booth
Openvz boothOpenVZ This document compares virtual machines (VMs) to containers and discusses their differences. It notes that VMs have higher overhead than containers and can support more instances per server. Containers offer near-native performance and scale better. The document also outlines ongoing and future work to further integrate container technologies into the Linux kernel to provide capabilities like checkpoint/restore and live migration of containers across servers.

OpenNebulaconf2017US: Paying down technical debt with "one" dollar bills by ...OpenNebula Project In addition to providing bare-metal access to large amounts of compute FAS Research Computing (FASRC) at Harvard also builds and fully maintains custom virtual machines tailored to faculty and researchers needs including lab websites, portals, databases, project development environments, and more both locally and on public clouds. Recently FASRC converted its internal VM infrastructure from a completely home-made KVM cluster to a more robust and reliable system powered by OpenNebula and Ceph configured with public cloud integration. Over the years as the number of VMs grew our home-made solution started to show signs of wear and tear with respect to scheduling, provisioning, management, inventory, and performance. Our new deployment improves on all of these areas and provides APIs and features that both help us serve clients more efficiently and improve our internal processes for testing new system configurations and dynamically spinning up resources for continous integration and deployment. Our new VM infrastructure deployment is fully automated via puppet and has been used to provision a multi-datacenter, fault-tolerant, VM infrastructure with a multi-tiered back-up system and robust VM and virtual disk monitoring. We will describe our internal system architecture and deployment, challenges we faced, and innovations we made along the way while deploying OpenNebula and Ceph. We will also discuss a new client-facing OpenNebula cloud deployment we’re currently beta testing with select users where users have full control over the creation and configuration of their VMs on FASRC compute resources via the OpenNebula dashboard and APIs.

The sexy world of Linux kernel pvops project
The sexy world of Linux kernel pvops projectThe Linux Foundation The document discusses paravirtualized operations (pv-ops) in the Linux kernel which allows it to detect if it is running under virtualization like Xen or KVM and use optimized operations. Pv-ops was successful and mainly involved bug fixes recently. Most Xen kernel development is in subsystems and amounts to over 50,000 lines of code added per release. Future work includes optimizations to blkback and netback drivers to improve I/O performance, as well as adding perf support and developing a hybrid PV/HVM domain 0 capability. The presenter takes questions at the end.

OpenNebula Conf 2014: CentOS, QA an OpenNebula - Christoph Galuschka
OpenNebula Conf 2014: CentOS, QA an OpenNebula - Christoph GaluschkaNETWAYS CentOS, the Community Enterprise OS, uses Opennebula as virtualization plattform for its automated QA-process. The opennebula setup consists of 3 nodes, all running CentOS-6, who handle the following tasks:
– sunstone as cloud controller
– local mirror/DNS-Server/http-Server for the VMs to pull in packages
– one VM to run a jenkins instance to launch the various tests (ci.de.centos.org)
– nginx on the cloud controller to forward http traffic to the jenkins VM
A public git repository (http://www.gitorious.org/testautomation) is used to allow whoever wants to contribute to pull the current test suite – t_functional, a series of bash scripts used to do funtional tests of various applications, binaries, configuration files and Trademark issues. As new tests are added to the repo via personal clones and merge requests, those tests first need to complete a test run via jenkins. Each test run currently consists of 4 VMs (one for each arch for C5 and C6 – C7 to come), which run the complete test suite. All VMs used for theses tests are instantiated and torn down on demand, whenever the call to testrun a personal clone is issued (via IRC).
Once completed successfully, the request is merged into the main repo. The jenkins node monitors this repository and which automatically triggers another complete test run.
Besides these triggered test runs, the test suite is automatically triggered daily to run. This is used to verify functionality of published updates – a handfull of failty updates have allready been discovered this way.
Besides t_functional, the Linux Test Project Suite of tests is also run on a daily basis, also to verify functionality of the OS and all updates.
The third setup is used to test the available and functional integrity of published docker images for CentOS.
All these tests are later – during the QA-phase of a point release – used to verify functionality of new packages inside the CentOS QA-Setup.
OpenNebula Administrator View
OpenNebula Administrator ViewOpenNebula Project OpenNebula provides features for high availability of virtual machines including migrating or recreating VMs if the host fails. It allows grouping VMs together by affinity like VM to host, VM to VM, or role to role. Network migrations can be optimized to use faster interfaces. Reusing VLANs involves collecting used IDs from the database and returning the first free ID. Virtual machines can utilize cgroups for CPU management, pass raw parameters to hypervisors, and use a guest agent for tasks like freezing for consistent snapshots or blocking during backups.

LCEU14: How to run a Collaborative Project - Lars Kurth
LCEU14: How to run a Collaborative Project - Lars KurthThe Linux Foundation Collaborative development is at the core of successful open source projects. Yet to be successful in today's competitive open source world, it is increasingly important to master many different disciplines and to develop an edge.
In this talk we will cover a wide range of topics relevant to developers and members of open source communities who want to increase participation in their projects. Topics range from growing your developer base (e.g. by participation in GSoC, OPW and similar programs), rewarding participation, projecting momentum in the media and press, coercing large companies into contributing more and in different ways to your project, running community initiatives successfully and measuring success.
We will use real-life examples and share tools and mental models (e.g. open source flywheel and funnels) that help you make the right decisions for your project.

First, we will examine interesting features of XAPI, such as events, pools etc. that allow easy administration of virtualized environment. Then, we will see how these features fit into the Xen Orchestra architecture, which has been completely redesigned to reduce connections, bandwidth waste, storing of structured data, allowing persistence and so on. Finally, we will show how we display all that information (ergonomics choices from an ergonomist). We will conclude quickly on how you can engage and contribute to the Xen Orchestra project and make sure it helps fulfil your needs.
Securing your cloud with Xen's advanced security features
Securing your cloud with Xen's advanced security featuresThe 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. However, 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.

Yet to be successful in today's competitive open source world, it is increasingly important to master many different disciplines and to develop an edge.
In this talk we will cover a wide range of topics relevant to developers and members of open source communities who want to increase participation in their projects. Topics range from growing your developer base (e.g. by participation in GSoC, OPW and similar programs), rewarding participation, projecting momentum in the media and press, coercing large companies into contributing more and in different ways to your project, running community initiatives successfully and measuring success.
We will use real-life examples and share tools and mental models (e.g. open source flywheel and funnels) that help you make the right decisions for your project.
Xen Orchestra: A new Web UI for XCP
Xen Orchestra: A new Web UI for XCPThe Linux Foundation
XCP exposes a fully featured management API called XAPI. But today, there is no active open source project providing a web GUI which uses XAPI to it's full potential. Xen Orchestra was originally designed as web interface for Xen in 2009, and is undergoing a complete re-write to fill this gap.

First, we will examine interesting features of XAPI, such as events, pools etc. that allow easy administration of virtualized environment. Then, we will see how these features fit into the Xen Orchestra architecture, which has been completely redesigned to reduce connections, bandwidth waste, storing of structured data, allowing persistence and so on. Finally, we will show how we display all that information (ergonomics choices from an ergonomist). We will conclude quickly on how you can engage and contribute to the Xen Orchestra project and make sure it helps fulfil your needs.
Securing your cloud with Xen's advanced security features
Securing your cloud with Xen's advanced security featuresThe 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. However, 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.
Xen, XenServer, and XAPI: What’s the Difference?-XPUS13 Bulpin,Pavlicek
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.
XCP Project Update
XCP Project UpdateThe Linux Foundation Lars will give an update on the latest development from the XCP project, standing in for Mike McClurg.

Why xen slides
Why xen slidesThe Linux Foundation Xen is an open source hypervisor originally developed in the late 1990s as part of the XenoServers project. It was designed to enable efficient virtualization on non-virtualizable hardware through paravirtualization. While the core of Xen remains open source under the Xen.org project, many companies offer proprietary products based on Xen like Citrix's XenServer and Xen Cloud Platform. Xen uses a "thin hypervisor" model where the hypervisor has minimal components and relies on separate service domains to handle tasks like device drivers and management. This architecture provides strong isolation, flexibility in component selection, and good scaling capabilities. Xen finds uses in server virtualization, cloud computing, desktop virtualization, client virtualization, and secure application isolation.
Containers - Cloud Phoenix March Meetup
Containers - Cloud Phoenix March MeetupMiguel Zuniga Linux containers allow running multiple isolated Linux systems on a single host. They provide operating system-level virtualization using kernel features like namespaces and cgroups. Containers can be used for running multiple software versions, tightly controlling application resources, and creating development/testing environments. Popular container technologies include OpenVZ and LXC, with Docker providing container management. Containers share the same OS kernel and hardware resources, providing better performance than virtual machines.
Develop with linux containers and docker
Develop with linux containers and dockerFabio Fumarola Docker allows building and running applications inside lightweight containers. Some key benefits of Docker include:
- Portability - Dockerized applications are completely portable and can run on any infrastructure from development machines to production servers.
- Consistency - Docker ensures that application dependencies and environments are always the same, regardless of where the application is run.
- Efficiency - Docker containers are lightweight since they don't need virtualization layers like VMs. This allows for higher density and more efficient use of resources.

ELC2019: Static Partitioning Made Simple
ELC2019: Static Partitioning Made SimpleThe Linux Foundation Static partitioning is used to split an embedded system into multiple domains, each of them having access only to a portion of the hardware on the SoC. It is key to enable mixed-criticality scenarios, where a critical application, often based on a small RTOS, runs alongside a larger non-critical app, typically based on Linux. The two domains cannot interfere with each other.
This talk will explain how to use Xen for static partitioning. It will introduce dom0-less, a new Xen feature written for the purpose. Dom0-less allows multiple VMs to start at boot time directly from the Xen hypervisor, decreasing boot times drastically. It makes it very easy to partition the system without virtualization overhead. Dom0 becomes unnecessary.
This presentation will go into details on how to setup a Xen dom0-less system. It will show configuration examples and explain device assignment. The talk will discuss its implications for latency-sensitive and safety-critical environments.

XPDDS19 Keynote: Unikraft Weather Report
XPDDS19 Keynote: Unikraft Weather ReportThe Linux Foundation In recent years unikernels have shown immense performance potential (e.g., boot times of only a few ms, image sizes of only hundreds of KBs).The fundamental drawback of unikernels is that they require that applications be manually ported to the underlying minimalistic OS, needing both expert work and often considerable amount of time.
The Unikraft project provides a unikernel code base and build system that significantly simplifies the building of unikernels. In addition to support for a number CPU architectures, languages and frameworks, Unikraft provides debugging and tracing features that are generally sorely missing from unikernel projects. In this talk we will talk about these features, show a set of preliminary performance numbers, and provide a roadmap for the project's future.

XPDDS19 Keynote: Xen Dom0-less - Stefano Stabellini, Principal Engineer, XilinxThe Linux Foundation This talk will introduce Dom0-less: a new way of using Xen to build mixed-criticality solutions. Dom0-less is a Xen feature that adds a novel approach to static partitioning based on virtualization. It allows multiple domains to start at boot time directly from the Xen hypervisor, decreasing boot times dramatically. Xen userspace tools, such as xl and libvirt, become optional.
Dom0-less extends the existing device tree based Xen boot protocol to cover information required by additional domains. Binaries, such as kernels and ramdisks, are loaded by the bootloader (u-boot) and advertised to Xen via new device tree bindings.
The audience will learn how to use Dom0-less to partition the system. Uboot and device tree configuration details will be explained to enable the audience to get the most out of this feature. The talk will include a status update and details on future plans.

OSSJP/ALS19: The Road to Safety Certification: Overcoming Community Challeng...The Linux Foundation Safety certification is one of the essential requirements for software to be used in highly regulated industries. Besides technical and compliance issues (such as ISO 26262 vs IEC 611508) transitioning an existing project to become more easily safety certifiable requires significant changes to development practices within an open source project.
In this session, we will lay out some challenges of making safety certification achievable in open source and the Xen Project. We will outline the process the Xen Project has followed thus far and highlight lessons learned along the way. The talk will primarily focus on necessary process, tooling changes and community challenges that can prevent progress. We will be offering an in-depth review of how Xen Project is approaching this challenging goal and try to derive lessons for other projects and contributors.

XPDDS19: Keeping Coherency on Arm: Reborn - Julien Grall, Arm ltdThe Linux Foundation The Arm architecture provides a set of guidelines that any software should abide by when accessing the memory with MMU off and update page-tables. Failing to do so may result in getting TLB conflicts or breaking coherency.
In a previous talk ("Keeping coherency on Arm"), we focused on updating safely the stage-2 (aka P2M) page-tables. This talk will focus on the boot code and Xen memory management.
During this session, we will introduce some of the guidelines and when they should be used. We will also discuss how Xen boot sequence needs to be reworked to avoid breaking the guidelines.
XPDDS19: QEMU PV Backend 'qdevification'... What Does it Mean? - Paul Durrant...
XPDDS19: QEMU PV Backend 'qdevification'... What Does it Mean? - Paul Durrant...The Linux Foundation For many years the QEMU codebase has contained PV backends for Xen guests, giving them paravirtual access to storage, network, keyboard, mouse, etc. however these backends have not been configurable as QEMU devices as their implementation did not fully adhere to the QEMU Object Model (QOM).
Particularly the PV storage backend not using proper QOM devices, or qdevs, meant that the QEMU block layer needed to maintain legacy code that was cluttering up the source. This was causing push-back from the maintainers who did not want to accept any patches relating to that Xen backend until it was 'qdevified'.
In this talk, I'll explain the modifications I made to QEMU to achieve 'qdevification' of the PV storage backend, how compatibility with the libxl toolstack was maintained, and what the next steps in both QEMU and libxl development should be.

XPDDS19: Bringing Xen to the Masses: The Story of Building a Community-driven...The Linux Foundation Xen is a very powerful hypervisor with a talented and diverse developers community. Despite the fact it's almost everywhere (from the Cloud to the embedded world), it can be difficult to set up and manage as a system administrator. General purpose distros have Xen packages, but that's just a start in your Xen journey: you need some tooling and knowledge to have a working and scalable platform.
XCP-ng was built to overcome those issues: by bringing Xen to the masses with a fully turnkey distro with Xen as its core. It's the logical sequel to the XCP project, with a community focus from the start. We'll see how it happened, what we did, and what's next. Finally, we'll see the impact of XCP-ng on the Xen Project.

We will present a case for maturing libxl’s Go bindings and discuss what advantages Go has to offer for high level toolstacks, including in the server space.
XPDDS19: Core Scheduling in Xen - Jürgen Groß, SUSE
XPDDS19: Core Scheduling in Xen - Jürgen Groß, SUSEThe Linux Foundation Today Xen is scheduling guest virtual cpus on all available physical cpus independently from each other. Recent security issues on modern processors (e.g. L1TF) require to turn off hyperthreading for best security in order to avoid leaking information from one hyperthread to the other. One way to avoid having to turn off hyperthreading is to only ever schedule virtual cpus of the same guest on one physical core at the same time. This is called core scheduling.
This presentation shows results from the effort to implement core scheduling in the Xen hypervisor. The basic modifications in Xen are presented and performance numbers with core scheduling active are shown.
