Stupid Video Tricks
AV Foundation makes it reasonably straightforward to capture video from the camera and edit together a nice family video. This session is not about that stuff. This session is about the nooks and crannies where AV Foundation exposes what's behind the curtain. Instead of letting AVPlayer read our video files, we can grab the samples ourselves and mess with them. AVCaptureVideoPreviewLayer, meet the CGAffineTransform. And instead of dutifully passing our captured video frames to the preview layer and an output file, how about if we instead run them through a series of Core Image filters? Record your own screen? Oh yeah, we can AVAssetWriter that. With a few pointers, a little experimentation, and a healthy disregard for safe coding practices, Core Media and Core Video let you get away with some neat stuff.

XPDS13: On Paravirualizing TCP - Congestion Control on Xen VMs - Luwei Cheng,...The Linux Foundation
While datacenters are increasingly adopting VMs to provide elastic cloud services, they still rely on traditional TCP for congestion control. In this talk, I will first show that VM scheduling delays can heavily contaminate RTTs sensed by VM senders, preventing TCP from correctly learning the physical network condition. Focusing on the incast problem, which is commonly seen in large-scale distributed data processing such as MapReduce and web search, I find that the solutions that have been developed for *physical* clusters fall short in a Xen *virtual* cluster. Second, I will provide a concrete understanding of the problem, and reveal that the situations that when the sending VM is preempted versus when the receiving VM is preempted, are different. Third, I will introduce my recent attempts on paravirtualizing TCP to overcome the negative effect caused by VM scheduling delays.More Related Content

XPDS16: Xen Orchestra: building a Cloud on top of Xen - Olivier Lambert & Jul...The Linux Foundation
Since its inception, the Xen Orchestra project which uses AGPLv3, always had a philosophy to listen and engage the community. User feedback shaped our initial concept, which first targeted system administrators. Eventually, our users drove us to support cloud-scale deployments supporting up to 2000 VM's. Retaining simplicity in usage and installation, while evolving Xen Orchestra to cloud scale posed many challenges. This led us to build many new features such ACLs, self-service, live charts, config drive management, and more, forced us to constantly evolve our architecture. First we will show how user needs changed our architecture, and how we implemented challenging problems such as user permissions, ACLs, Containers in a virtualized infrastructure and self service. We will conclude with a short demo, what is next and a lessons learned.XPDS16: Live Migration of vGPU - Xiao Zheng, Intel Asia-Pacific Research & De...
XPDS16: Live Migration of vGPU - Xiao Zheng, Intel Asia-Pacific Research & De...The Linux Foundation
GPU virtualization is hot in cloud usages including VDI, media processing, etc. While Intel GVT-g (a.k.a XenGT) helps unleash those compelling usages on Intel Processor Graphics, new requirements are emerging such as VM live migration with vGPU. In this session we will introduce the challenges of supporting vGPU live migration on current migration framework, then elaborate techniques to bring vGPU live migration into XenGT.XPDS16: Making Migration More Secure - John Shackleton, Adventium Labs
Live virtual machine migration is a crucial operation in the day-to-day management of modern cloud environments. For systems with the highest security requirements, standard migration protocols must be ammended to protect against a number of failure or cyberattack scenarios. In this presentation, we explore these scenarios and discuss extensions to various Xen toolstacks to protect against potential vulnerabilities.
XPDS16: Xen Development Update
The talk is a status report for the latest release and development projects. It will cover the new features and important bug fixes (if any) in 4.7. It will also provide insight on what’s in the queue for the next major release. Retrospective on the release process will also be part of talk.
XPDS16: libvirt and Tools: What's New and What's Next - James Fehlig, SUSE
A year has passed since the last Xen Developer Summit and it is time to announce the quiet progress made on the libvirt libxl driver and related tooling. New features include memory, cpu, block device, and network interface statistics reporting, support for pvUSB, support for migration stream V2, peer-to-peer migration, UEFI for HVM guests via OVMF, and domain capabilities reporting to name a few. There are also many noteworthy improvements such as better conversion of xl.cfg to/from libvirt domXML, allowing users to easily switch between the xl+libxl and libvirt+libxl toolstacks.
The summit also provides an opportunity to discuss new proposals such as better control of domain placement on NUMA systems, exposing Xen's cpu pool feature in libvirt, supporting non-volatile memory for UEFI variables, and improved capabilities reporting.
Much of libvirt's value for Xen is in the tools built upon it: virt-manager, virt-viewer, virt-install, virt-builder, kimchi, OpenStack nova, etc. These tools also deserve a quick status update as they relate to Xen.
The audience is encouraged to participate, e.g. by requesting a sorely missing feature, warning of an upcoming Xen change that may affect libvirt, or simply suggesting a change that makes virtualization management life a bit easier.
XPDS16: Patch review for non-maintainers - George Dunlap, Citrix Systems R&D...
As the number of contributions grow, reviewer bandwidth becomes a bottleneck; and maintainers are always asking for more help. However,
ultimately maintainers must at least Ack every patch that goes in; so if you're not a maintainer, how can you contribute? Why should anyone care about your opinion?
This talk will try to lay out some advice and guidelines for non-maintainers, for how they can do code review in a way which will effectively reduce the load on maintainers when they do come to review a patch.
Fosdem 17 - Towards a HVM-like Dom0 for Xen
Subtitle: Reducing the OS burden while taking advantage of new hardware features
Xen is a hypervisor using a microkernel design that allows running multiple concurrent operating systems on the same hardware. One of the key features of Xen is that it is OS agnostic, meaning that any OS (with proper support) can be used as a host. Xen has a long history going back to the 90s when it was designed and the early 2000s when it was released. As a consequence of this, many of the assumptions and virtualization techniques backed into it are now superseeded by new hardware features, that make virtualization more transparent from an OS point of view.
This talk provides an overview on the different kind of guests supported by Xen and how these new hardware features are used in order to improve and evolve them. It also describes the design and implementation of a new guest type, called PVHv2, and how it can be used as a control domain (Dom0).

XPDS16: Scope and Performance of Credit-2 Scheduler. - Anshul Makkar, Ctirix...
Credit 2 Scheduler was designed with the following goals in mind: to be functionally complete, have algorithmic improvements, be scalable, and have improved performance compared to Credit 1 Scheduler. Various tests were performed measuring boot times, login times, network throughput, and storage performance on systems with varying numbers of VMs, CPUs, RAM, and storage configurations. Credit 2 Scheduler demonstrated improvements over Credit 1 Scheduler across most of the metrics tested.
XPDS16: CPUID handling for guests - Andrew Cooper, Citrix
Migration of virtual machines without guest downtime is a key feature for hypervisors. Sadly, not all hardware is the same, and keeping guests running in a heterogeneous environment takes a lot of care. Normally, features are advertised via the CPUID instruction, but life is never as simple as we would like. Andrew will discuss what information needs to be controlled, what information can and can't be controlled, and how it applies to Xen guests.
XPDS16: Keeping coherency on ARM - Julien Grall, ARM
The ARM architecture strongly recommends to use a break-before-make when changing translation table entries whenever certain conditions are met. Failing to do so may result in getting TLB conflicts or breaking the coherency.
During this session, we will introduce break-before-make and when the code handling page tables should use it. We will also discuss the modifications required in Xen to avoid breaking the coherency.

We see several challenges because of the unique (but not unusual for HPC) hardware technologies and performance requirements. For example, such hardware technologies include 1) >256 CPUs, 2) MCDRAM (high-bandwidth memory), 3) integrated fabric (i.e. Intel® Omni-Path). Unlike the “coprocessor“ model, supporting self-boot with >256 CPUs has various implications to Xen, including scheduling and scalability. We need to allow user applications to use MCDRAM directly to perform optimally. Also, we need to enable the integrated HPC fabric for the VM to use by direct I/O assignment.
In addition, we have only a single VM on each node to meet the high-performance requirements of HPC clouds. This (i.e. non-shared) model allowed us to optimize Xen more. In this talk, we share our design and lessons, and discuss the options we considered to achieve high-performance virtualization for HPC.XPDS16: Hypervisor-based Security: Vicarious Learning via Introspektioneerin...
This presentation is based on the technical hurdles we overcame when building a commercial product on the introspection capabilities of the Xen hypervisor. Mihai Dontu will relate the importance of the x86 emulator, the need for a more focused effort on its completeness and correctness, the problems encountered, and the solutions adopted. He will also approach the subject of performance, for which hypervisor features that were not meant to be in the hot path had to be punctually reworked to solve a key requirement for making a theoretical product a commercial reality.
LF Collaboration Summit: Xen Project 4 4 Features and Futures
Xen Project 4.4 Release Information.
Delivered by Russell Pavlicek at Linux Foundation Collaborative Summit on March 27, 2014.
Updated for LinuxCon/CloudOpen North America in August 2014.
Performance Tuning Xen
How to tune your Xen deployment for performance: Xen has several options and different kinds of guests, knowing when to use each kind of guest, and how to tune its parameters for optimal performance can make a big difference. This talk will cover the types of guests that can be deployed on Xen, and the different options you can use to obtain the best performance.
XPDS16: Porting Xen on ARM to a new SOC - Julien Grall, ARM
Adding support for you new shiny board in Xen on ARM is a simple task once you get a kernel running on bare metal.
This session will cover the different steps to port Xen on ARM from the firmware to the shell prompt in DOM0.
We will give you tips on the common pitfalls when you have your hypervisor, or your DOM0 kernel crashing. We will also provide suggestion on how to debug when the console is not working.

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.LinuxCon Japan 13 : 10 years of Xen and Beyond
This document discusses the Xen Project community and hypervisor architecture. It notes that Xen.org has become XenProject.org to be more vendor neutral. The contributor community has diversified with more active vendors. Xen is used in large clouds and powers more than 10 million individual users. The hypervisor can run in paravirtualized (PV) or hardware virtualized (HVM) modes. PV is faster while HVM requires no kernel support. XAPI provides management functions for live migration, storage, resource pools, and monitoring across multiple hosts. Disaggregation of the control domain into separate driver and service domains improves security, robustness and performance. Xen also supports ARM servers through a fully functional hypervisor for ARMv7 and ARMv8

Poky meets Debian: Understanding how to make an embedded Linux by using an ex...
Embedded Linux Conference 2015
Poky has already become one of the most popular build system to make an embedded Linux environment. Poky refers to OpenEmbedded originally. However if you want to use other source code, how to do it? We have some experience we would like to share with you. For this study, We choose Debian source and already tried two ways to use it. The first try was probably an incorrect way and the second try may be a correct way.
In this talk, we will show both of them and also describe why we choose Debian. If you are interested in this implementation, you can download the source code from GitHub. There are some implementations available for development boards such as pandaboard, minnowboard and etc. Let's enjoy Bitbake!

Linux day 2016 Yocto Project
The Yocto Project is a collaborative open source project that provides prototypes, tools and methods that let you create personalized Linux-based systems for embedded products independent from the hardware architecture. The project was born in 2010 as a partnership of many different hardware manufacturers, open-source operative systems providers and electronic companies, to bring some order to the chaos that was the development of Linux Embedded. Why use Project Yocto? Because it's a development environment for Linux embedded complete with tools, meta-data and documentation - everything that one needs. The free of charge tools that Yocto makes available are powerful and easy to generate (included emulation environments, debuggers, a tool-kit to generate applications and others) and they let you create and continue projects, without causing you a loss of optimizations and investments made in the prototyping phase. Project Yocto supports the adoption of this technology by the open-source community letting users concentrate on the characteristics and development of their product.

MacSysAdmin Tools Smörgåsbord
This session was presented at MacSysAdmin 2015 in Göteborg, Sweden. Video recordings can be found at: http://docs.macsysadmin.se/2015/2015doc.html
Session description follows:
As a Mac sysadmin, I've found some tasks I knew I was going to need to automate with scripts or die of boredom. And sometimes, what begins as a curious "Wouldn't it be cool if.." coding experiment evolves into something that solves a real problem.
Over time, I've built up a small collection of tools related to OS X deployment and automation that I've released on GitHub in the hopes that others might also find them useful. In this session I'll tour some of these utilities, explain how they came to be and demonstrate their use.

Streamline your development environment with docker
These days applications are getting more and more complex. It's becoming quite
difficult to keep track of all the different components an application needs in order to
function (a database, a message queueing system, a web server, a document
store, a search engine, you name it.). How many times we heard 'it worked on my
machine'?. In this talk we are going to explore Docker, what it is, how it works
and how much it can benefit in keeping the development environment consistent.
We are going to talk about Dockerfiles, best practices, tools like fig and vagrant,
and finally show an example of how it applies to a ruby on rails
application.

Mapreduce - Simplified Data Processing on Large Clusters
The document describes MapReduce, a programming model and implementation for processing large datasets across clusters of computers. It allows users to write map and reduce functions to parallelize tasks. The MapReduce library automatically parallelizes jobs, distributes data and tasks, handles failures and coordinates communication between machines. It is scalable, processing terabytes of data on thousands of machines, and easy for programmers without parallel experience to use.
Web Server Clustering - OSSCAMP
The document discusses different types of clusters used for load balancing, high availability, and distributed computing. It describes DNS round robin and open source load balancing packages that can be used. It also discusses the Linux Virtual Server (LVS) project which performs load balancing at the TCP/IP level and supports scheduling algorithms. High availability clustering is achieved through heartbeat which allows nodes to monitor each other and switch roles if a primary node fails. Storage clusters can be implemented using distributed replicated block devices (DRBD) and network file systems (NFS).

Une évaluation comparable de la performance basée sur le temps d'escale des navires
L'objectif de l'ICPP est d'identifier les domaines d'amélioration qui peuvent en fin de compte bénéficier à toutes les parties concernées, des compagnies maritimes aux gouvernements nationaux en passant par les consommateurs. Il est conçu pour servir de point de référence aux principaux acteurs de l'économie mondiale, notamment les autorités et les opérateurs portuaires, les gouvernements nationaux, les organisations supranationales, les agences de développement, les divers intérêts maritimes et d'autres acteurs publics et privés du commerce, de la logistique et des services de la chaîne d'approvisionnement.
Le développement de l'ICPP repose sur le temps total passé par les porte-conteneurs dans les ports, de la manière expliquée dans les sections suivantes du rapport, et comme dans les itérations précédentes de l'ICPP. Cette quatrième itération utilise des données pour l'année civile complète 2023. Elle poursuit le changement introduit l'année dernière en n'incluant que les ports qui ont eu un minimum de 24 escales valides au cours de la période de 12 mois de l'étude. Le nombre de ports inclus dans l'ICPP 2023 est de 405.
Comme dans les éditions précédentes de l'ICPP, la production du classement fait appel à deux approches méthodologiques différentes : une approche administrative, ou technique, une méthodologie pragmatique reflétant les connaissances et le jugement des experts ; et une approche statistique, utilisant l'analyse factorielle (AF), ou plus précisément la factorisation matricielle. L'utilisation de ces deux approches vise à garantir que le classement des performances des ports à conteneurs reflète le plus fidèlement possible les performances réelles des ports, tout en étant statistiquement robuste.
