Virtual Meetup Docker + Arm: Building Multi-arch Apps with BuildxDocker, Inc.

This document discusses building multi-architecture Docker images using Docker Buildx. It introduces the concepts of multi-architecture images, describes the traditional method of building separate images for each architecture and combining them with manifest lists, and recommends using Buildx which can build images for multiple architectures simultaneously during a single build. Buildx allows building on the host architecture natively or emulating other architectures. The document emphasizes that applications should support multiple platforms and architectures, and encourages always using multi-stage Dockerfiles and considering Buildx as an improved alternative to the older manifest-based approach.

Docker is an open platform for developing, shipping, and running distributed applications. It allows applications to be shipped and run in lightweight containers that can run on any Linux server. Docker uses operating-system-level virtualization and cgroups isolation to deliver lightweight containers quickly. Key features of Docker include portability, lightweight containers that share resources and isolate processes, and automated workflows.

kdump: usage and_internalsLinuxCon ContainerCon CloudOpen China

Kdump is a long existing method for acquiring dump of crashed kernel, however very few literatures are available to understand it's usage and internals. We receive a lot of queries on kexec mailing list about different issues related to the kexec/kdump environment. In this presentation, we talk about basics of kdump usage and some internals about kdump/kexec kernel implementation. It includes end to end flow from kdump kernel configuration to crash analysis. We discuss some of the problem which is frequently faced by kdump users. It also includes related information about ELF structure, so that one can debug if vmcore itself gets corrupted because of any architecture related issue.

Slides of Kubernetes Athens Meetup vol3 - Unikernels An alternative OS Archit...Nikos Zois

This presentation is a part of Kubernetes meetup vol3 @ Athens. At the very beggining we explain how we manage until now to come closer to the virtual hardware, removing possible duplication layers, that appear between the hypervisor and the Virtual Machine. An alternative solution removing duplication layers is Unikernels. Having small sized VM including only hypervisor libraries and our application in the same level (kernel), we build a Custom Virtual Machine targeting smaller footprint, reduced latency and better security. Next we explain very fast the OSv unikernel that allow us to compose a linux service built as shared object within the unikernel. Finnally we see a benchmark of a Redis Cluster that is running on OSv unikernels.

What is DockerPavel Klimiankou

Docker allows you to package applications with their dependencies into standardized units called containers that can run on any Linux server. Containers are more portable and efficient than virtual machines, starting in milliseconds and using less disk space. Docker makes it easy to deploy and run applications without having to rebuild environments and guarantees that an application will run the same regardless of the infrastructure it is running on.

runC: The little engine that could (run Docker containers) by Docker Captain ...Docker, Inc.

With the announcement of the OCI by Solomon Hykes at last summer's DockerCon, a Docker-contributed reference implementation of the OCI spec, called runC, was born. While some of you may have tried runC or have a history of poking at the OS layer integration library to Linux namespaces, cgroups and the like (known as libcontainer), many of you may not know what runC offers. In this talk Phil Estes, Docker engine maintainer who has also contributed to libcontainer and runC, will show what's possible using runC as a lightweight and fast runtime environment to experiment with lower-level features of the container runtime. Phil will introduce a conversion tool called "riddler", which can inspect and convert container configurations from Docker into the proper OCI configuration bundle for easy conversion between the two environments. He'll also demonstrate how to make custom configurations for trying out security features like user namespaces and seccomp profiles.

Docker puppetcamp london 2013Tomas Doran

The document discusses using Docker containers and Puppet to compartmentalize services running on a personal server. Previously, many services like Postfix, Dovecot, DNS, etc. were running on the server with no isolation. The approach taken was to define Puppet profiles for each service, build Docker containers from those profiles, and run the containers independently with their own isolated environments. This improves security, ease of development and deployment, and allows immutable infrastructure by replacing containers instead of changing server configurations. Challenges discussed include Docker bugs, inconsistent Debian packages, and future plans to add HAProxy and a container registry.

Quickly Debug VM Failures in OpenStackLinuxCon ContainerCon CloudOpen China

This document discusses how to quickly debug VM failures in OpenStack. It begins by explaining where VMs run in OpenStack and how VM startup is implemented. It then describes how to use various logs from OpenStack components like Nova, Neutron, and libvirt/Qemu to troubleshoot issues. The document also provides examples of common VM failure types and outlines steps for debugging, including checking configuration settings, log files, and using troubleshooting tools like Virsh and ABRT. Finally, it calls for collecting VM failure scenarios and solutions to integrate into monitoring tools like StackTach.

XPDDS19: Implementing AMD MxGPU - Jonathan Farrell, Assured Information SecurityThe Linux Foundation

Jon Farrell summarizes his experience implementing AMD MxGPU virtualization. He began by learning about MxGPU on GitHub and setting up an Ubuntu server with Xen. Initial setup involved building a custom kernel, blacklisting amdgpu, and enabling IOMMU. Guest preparation required installing a VNC server and driver. Difficulties included choosing the right Xen version, starting modules, kernel building, and MxGPU patches. Performance metrics were estimated based on similar benchmarks. Overall, Farrell learned about building Xen, custom kernels, guest VMs, and device passthrough with XL. He sees potential for this technology in cloud gaming platforms and Xen virtualization.

Kvm and libvirtplarsen67

LibVirt and KVM provide virtualization capabilities on Linux systems. LibVirt uses a standardized API to manage different hypervisors like KVM. KVM allows running virtual machines at native speeds by using hardware virtualization extensions. It provides high density and portability compared to running systems directly on hardware. LibVirt handles tasks like networking, storage, and interfaces through tools like Virsh and Virt-Manager, and advanced topics include security with SELinux, bridged networking, and remote access.

virtualization and hypervisorsGaurav Suri

The document discusses a mid-evaluation of a major project comparing several hypervisors. It will compare Xen, KVM, VMware, and VirtualBox based on their technical differences and performance benchmarks. The benchmarks will test CPU speed, network speed, I/O speed, and performance running various server workloads. This comparison will help determine the best hypervisor for a given virtualization situation. Key factors that will be compared include OS support, security, CPU speed, network speed, I/O speed, and response times.

DevOps Braga #11: Docker AnatomyDevOps Braga

- Docker containers and virtual machines both enable isolation of applications but use different approaches. - Virtual machines run a full operating system and require virtualization software to abstract the underlying hardware. Docker containers leverage the same kernel as the host operating system and provide isolation through kernel namespaces and cgroups. - Containers are more portable and lightweight since they don't require guest operating systems, but virtual machines have stronger isolation since each has its own kernel.

The document discusses virtualization and provides an overview of key concepts and types of virtualization. It defines virtualization as using software to create virtual versions of hardware resources like servers, storage, and networks. The summary discusses the main types of virtualization covered in the document: 1. Server virtualization allows consolidating multiple physical servers onto one server by virtualizing hardware resources. 2. OS virtualization works at the OS layer, virtualizing a physical server and OS into isolated partitions that function like separate servers. 3. Hardware emulation uses a hypervisor to emulate hardware for guest operating systems, allowing different OS types on one server. 4. Paravirtualization coordinates hardware access without fully emulating

This document provides an overview of virtualization technologies for high performance computing environments. It discusses what virtualization and hypervisors are, as well as common hypervisors like Xen, KVM, and VirtualBox. The document analyzes these hypervisors based on features, usability, and performance benchmarks. Benchmark results are presented from running SPEC CPU, memory, and I/O benchmarks, as well as HPCC benchmarks, on virtual machines created with each hypervisor compared to native hardware. The analysis finds that all hypervisors provide acceptable virtualization features for HPC and that Xen supports the most resources but also has more complex installation.

VirtualizationKumar Harsha

Virtualization involves dividing the resources of a computer into multiple execution environments. It has been used since the 1960s and there are several types including hardware, desktop, and language virtualization. The key components of a virtualization architecture are the hypervisor and guest/host machines. Hypervisors allow multiple operating systems to run on a single system and can be type 1 (runs directly on hardware) or type 2 (runs within an operating system). Virtualization provides benefits but also has limitations related to resource allocation and compatibility that vendors continue working to address.

Virtualize All the Things!David Pechon

Virtualization allows organizations to get more from their existing hardware resources, improve recovery times, and enable flexible disaster recovery. It has been used for decades to run mission critical workloads on virtual machines. Modern virtualization technologies from VMware and Microsoft provide robust management and automation capabilities. While virtualization was initially focused on servers, it can now virtualize various infrastructure components including desktops, storage, and networking through software-defined approaches.

It discusses that Docker virtualizes using lightweight Linux containers rather than full virtual machines, and how this provides benefits like smaller size and faster performance compared to VMs. It also covers Docker's components like the Docker Engine, Hub and images, and how Docker can be used to develop, ship and run applications on any infrastructure.

The Lies We Tell Our Code (#seascale 2015 04-22)Casey Bisson

This document discusses various lies and forms of virtualization that are commonly used in computing. It begins by summarizing different virtualization technologies used at Joyent like zones, SmartOS, and Triton. It then discusses lies told at different layers of the stack, from virtual memory to network virtualization. Some key lies discussed include hyperthreading, paravirtualization, hardware virtual machines, Docker containers, filesystem virtualization techniques, and network virtualization. The document argues that many of these lies are practical choices that improve performance and workload density despite not perfectly representing the underlying hardware. It concludes by acknowledging the need to be mindful of security issues but also not to stop lying at the edge of the compute node.

Virtualization allows software to be tested under different platforms and configurations without needing to set up each environment separately. Popular virtualization tools include VmWare, Oracle VirtualBox, KVM, and XEN. Vagrant is also introduced as a tool that allows portable development environments to be created and deployed easily across different infrastructures using provisioning scripts. The document provides commands for initializing, running, connecting to, and deleting Vagrant environments.

Unikernels: Rise of the Library HypervisorAnil Madhavapeddy

Handout2oShahbaz Sidhu

Virtualization allows multiple virtual machines to run on a single physical machine. It relies on hardware advances like multi-core CPUs and networking improvements. Virtualization works by either emulating hardware, trapping privileged instructions and emulating them, dynamic binary translation, or paravirtualization where the guest OS is aware it is virtualized. I/O virtualization can emulate devices, use paravirtualized drivers, or directly assign devices to VMs. This enables server consolidation and efficient utilization of resources in cloud computing.

OpenVZ Linux ContainersKirill Kolyshkin

The talk is about operating system virtualization technology known as OpenVZ. This is an effective way of partitioning a Linux machine into multiple isolated Linux containers. All containers are running on top of one single Linux kernel, which results in excellent density, performance and manageability. The talk gives an overall description of OpenVZ building blocks, such as namespaces, cgroups and various resource controllers. A few features, notably live migration and virtual swap, are described in greater details. Results of some performance measurements against VMware, Xen and KVM are given. Finally, we will provide a status update on merging bits and pieces of OpenVZ kernel to upstream Linux kernel, and share our plans for the future.

aws.pptssuser52d2d8

Virtualization allows multiple operating systems to run on a single physical machine by sharing hardware resources. A hypervisor manages virtual machines and isolates them so they can run independently without disruption. There are two types of hypervisors: type 1 runs directly on hardware while type 2 runs on a conventional operating system. Docker provides operating system-level virtualization through containers that package apps and dependencies. Amazon EC2 allows launching virtual servers in the cloud using Amazon Machine Images as templates. Users generate a key pair for authentication and launch instances to customize and connect to virtual servers in AWS.

A Framework for Information Access in Rural and Remote CommunitiesSameer Verma

Access to information is predicated on the access to a digital infrastructure. However, access to electricity and the Internet remain elusive for a significant percentage of the world's population, let alone a sustainable access in one’s local language, local context, and relating to local culture. This paper examines the issues of resource constraints, and proposes a framework to classify them. It then proceeds to utilize this framework to look at three different case studies of implementations of offline Internet access in Madagascar, Jamaica and India.

Juju, LXC, OpenStack: Fun with Private CloudsSameer Verma

Description: Private clouds fill an interesting space in the cloud roadmap. They can provide a scalable, reliable, fault-tolerant cloud platform on your own infrastructure, and can be balanced with public cloud offerings. We will look at three technologies. OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface. Juju, a cloud orchestration platform from Ubuntu, enables you to build entire environments in the cloud with only a few commands on public clouds like Amazon Web Services and HP Cloud, to private clouds built on OpenStack. LXC is the userspace control package for Linux Containers, a lightweight virtual system mechanism sometimes described as “chroot on steroids”. LXC builds up from chroot to implement complete virtual systems, adding resource management and isolation mechanisms to Linux’s existing process management infrastructure. How cool would it be, to walk around with a private cloud on your laptop?

Drupal and the Semantic WebSameer Verma

Data by itself is simply a collection of numbers. It only becomes meaningful when we weave it through context. A context of relevance that creates information - provides insight, creates solutions and solves problems. The Web gives us a fabric of connectedness, but if the data isn't substantiated semantically, the information we create isn't very useful. By building effective web assets using platforms like Drupal, we build ways to solve problems across the spectrum from local to global. We not only build the Web the way it was meant to be, but we also build it to support a commons across community, enterprise and government for generations to come.
