CLI tools in Python + interesting/useful packages

Feedback Survey

You can take advantages of Python even you don't know the language!

One part of this session would be focused on useful python modules, that can be used as command line tools in your scripts - knowledge of python is not required.

By the rest of time I would like to show you subset of interesting python packages available on PyPi and how these tools can you help to avoid reinventing wheel. Ready for action? :-)

You can looking forward to a lot of demos.

Analyzing KVM BlockIO event latency

Feedback Survey

The workshop init script 'vm_env_setup.sh' is in http://github.com/arcolife/latency_analyzer/

So, this is an ongoing investigation of KVM blockIO event tracing and analysis, within the performance engineering team at Red Hat. During this process, we have come come across a few anomalies which we'd like to share with the community to gain support and contribution for tooling/kernel modules of Linux, associated with performance. We have, as a part of this investigation, also released a couple of tools, which we'd like to showcase at DevConf.

This talk is intended for system admins as well as those seeking general performance tuning/analysis. The lab would be a mix of a brief overview followed by a hands on tracing of events, analysis of a test case and reaching conclusions based on that result.

The project link is a work in progress but we have released some utilities and will continue to work on the following repositories as well:
- http://github.com/psuriset/kvm_io/
- http://github.com/arcolife/perf-script-postprocessor

Please note that vm_env_setup.sh runs perfectly on fedora 23. If you have other distros/versions, kindly at least do the following, to speed up the workshop:

install the pip2 module perf-script-postprocessor. You might get dependency erros on rpm based systems. So install the equivalent of following packages.
gcc lapack lapack-devel blas blas-devel gcc-gfortran gcc-c++ liblas libffi-devel libxml-devel libxml2-devel libxslt-devel redhat-rpm-config
install @Virtualization packages for your distro, as well as qemu-kvm ..so we could use virsh / virt-install / qemu-kvm as accelerator..
run the following part from vm_env_setup.sh, as following..

# ./handy_minimalistic.sh

Cheers.

Docker, Vagrant and Kubernetes walks into an Eclipse'd bar

Feedback Survey

Todays software industry is booming with tools like Docker, Kubernetes, Vagrant and more to enable faster turnaround times via virtualization.

How does Eclipse the IDE deal with that ? Can it deal with it ? How should it and its users deal with it ?

Come to this talk and hear how and what Eclipse Linux Tools and JBoss Tools are doing in the area.

It will give a brief overview on the Docker and Vagrant tooling in Linux Tools and then how that is used and combined in Kubernetes and OpenShift Tools.

The talk will show how you can use Docker and Vagrant practically today with plain Eclipse to improve your own local development experience and then shortly cover how it all comes together in the cloud and container space.

Some basic understanding of the container and virtualization technologies are recommended, but not an absolute requirement.

Speakers

Feedback Survey

As we scale to run containers from dev environment to multi-host production environment, we need tools to orchestrate the container deployment. Some of the tools are :-

- Docker Swarm
- Kubernetes
- Mesos

We would use pre-baked Vagrant VMs with the above tools installed on them and then deploy same apps on all of them one by one. After that we’ll do the comparative study.

Image Factory

Feedback Survey

The Image Factory project began as a standalone service for building and uploading images to public and private clouds. Over time it has evolved to support a number of image types beyond cloud and to play a key role in the creation and delivery of images for Fedora, RHEL and CentOS, via integration with the koji build system.

In this talk I'll give an overview of the design philosophy behind Image Factory, and a key underlying component, Oz. I'll demonstrate how Oz and Image Factory make use of both libvirt and libguestfs to simplify the tasks associate with creating virtual machines for system installation and modifying the resulting output.

I'll go on to describe how Image Factory has been integrated into koji and how this integration has driven us to support new non-cloud image formats such as Docker and Vagrant.

Finally, bandwidth-willing, I'll demo some image builds, both locally and in koji.

Docker for Developers

Feedback Survey

Docker is not just for deployment. As a developer, there are many ways Docker can make you more productive, regardless of how your app gets deployed.

In this session, you will learn practical strategies for using Docker, including how to:

- Run unit tests locally in multiple environments with almost no overhead.
- Make your integration tests easy for anyone to run by distributing them in a Docker image.
- Simulate advanced network topologies, especially for a service-oriented architecture.
- Make a Docker image in 5 minutes or less that produces builds from a consistent environment.
- Isolate database state changes in your test suite by using a pool of disposable containers.

So you want to have a modern infrastructure

Feedback Survey

Thanks to the rise of SaaS, starting a free software project have
never been as easy than now. Yet, the proprietary nature of most services
make them quite often inflexible, and therefor unsuitable for some
kind of project, thus requiring to deploy your own infrastructure.

However, while lots of documentations exist on the web, most of them
are either outdated, incomplete or not suitable, and there is almost
no guidance on the best practices for system administration for community
project, and what kind of measure are practical and efficient
for sysadmins with less time than usual.

So this talk will explore the best practices in term of security and
deployment for a project infrastructure, from ssh security to
centralized logging and authentication, focusing on the quick
wins and explaining what will they bring to the table.

Host fencing in oVirt - Fixing the unknown and allowing VMs to be highly available

Feedback Survey

In order to support highly available VMs, oVirt needs a mechanism to determine the status of a VM running on non-responsive host. We need to be sure that VM is not running before restarting it on a different host to prevent data corruption. And oVirt fencing flow is crucial to achieve this goal.

Host fencing flow is a part of oVirt host monitoring, it takes care of non-responsive hosts and tries to make them responsive again. We will describe each step of the whole fencing flow on real world issues, describe what actions around hosts/VMs are taken after each step of fencing flow and also describe how power management interface of the hosts is used.

Java EE 7 Hands-on Lab with JBoss Forge

Feedback Survey

Automating tedious user tasks can increase productivity and save you money. While there are numerous tools for the continuous integration of software, many developers still rely on hand-made shell scripts, clumsy integrated development environment (IDE) wizards, or endless Google searches for generating companion project artifacts like dependency-management settings, database and ORM configuration, simple CRUD services, test-environment setup, or deploying into the cloud. JBoss Forge fills that niche in the software-development life cycle. JBoss Forge offers: A simple, modular, easy-to-grasp model for developing pluggable components that can fit in any phase of a programmer's daily life. The ability to use any programming language, database, or server you choose. An easy, testable way to define your own tools, wizards, and extensions.

Performance tuning of virtual machines and containers

Feedback Survey

Virtual machines and containers are everywhere. They have become an important part of not only developer's live but mainly system administrators and whole enterprise environment. With that huge impact, the performance is becoming more important. In my talk I am going to show various approaches since performance is tied to given use case. While some users have some dedicated machines for virtualization and can isolate most of their CPUs for virtual machine's sake, usual developers on desktops almost certainly will not do that. And while I/O throughput is important for databases running in virtual machines, rendering a video aims at something else: vCPU and memory throughput. I'm going to cover these in my talk. Moreover, the use cases will be covered with live demos too.

rdopkg: power to the packagers

Feedback Survey

I wrote rdopkg to automate boring and repetitive tasks related to RPM packaging of OpenStack *client projects and it grown to contain quite a lot of white automagic to make packagers' lives easier.

rdopkg contains functionality to easily keep RPM packages up to date with upstream while managing downstream patches in git patches branches[2] (as opposed to plain .patch files). It can easily manage downstream patches and even rebase package distgit[3] to new upstream release. It also contains utilities for managing python requirements.txt files and much more we need to package OpenStack into RDO/Fedora.

This workshop is for RPM packagers. If you maintain an RPM package that carries some patches, rdopkg will probably save you a lots of time and pain. I'll show you what conventions you need to follow in your dist-git and howto setup your repo[4] in order for rdopkg to work.

I'll demonstrate basic packaging tasks with rdopkg, especially managing patches and rebasing a package to a new upstream version. I'll provide real life examples of rdopkg-managed packages from RDO. Based on your interest, I can also dive into more fancy functionality rdopkg provides such advanced python requirements.txt management or whatever you're interested in[4].

I'll also talk about how rpkg/fedpkg sucks[5] and why I plot to create an ultimate RPM packaging framework called pwnpkg[5] and finally give the world fedpkg it deserves. Join me in the glorious packaging revolution! :)

How to build the fastest multilingual VM

Feedback Survey

How would you design and write your new language to make it awesome and fast?

Let’s assume our language design is awesome and focus on how to make it fast.
The usual approach to programming language implementation is: an AST
interpreter prototype, an AST interpreter in C++, a byte-code interpreter, and
then add a JIT compiler. But this can take decades.

This presentation will show an alternative way of creating fast programming
language implementation in a single step: Truffle AST interpreters. We'll look
at the key technologies making this possible: the Graal compiler and the
Truffle framework. Graal is a modern, dynamic, clean, JIT compiler with
aggressive speculative optimizations. It's written in Java and provides APIs
which are used by Truffle, a self-optimizing AST interpreter, to generate
highly optimized machine code for many different languages.

in-depth look of virtual machine migration algorithms

Feedback Survey

Pre-copy live migration refers to the process of moving a running virtual machine or application between dierent physical machines without disconnecting the client or application. A live migration keeps the guest running on the source host and begins moving the memory without stopping the guest. All modied memory pages are monitored for changes and sent to the destination while the image is sent. The memory is updated with the changed pages. The process continues until the amount of pause time allowed for the guest equals the predicted time for the nal few pages to be transferred.

A problem with pre-copy live migration is that depending on the access pattern in the guest system, the migration process might be unable to reduce the number of dirty pages below the number necessary for the congured pause time to be met.

This presentation analyzes the optimal pattern to copy memory assuming the guest access pattern is cyclic and known in advance.

Avocado and Jenkins: Test Automation and CI

Feedback Survey

Continuous integration (CI) is a practice where isolated changes
and/or patches are immediately tested and reported on when they
are added either upstream or downstream. The goal of CI is to
provide rapid feedback so that if a defect is introduced into the
code base, it can be identified and corrected as soon as possible.
The libvirt and qemu communities are promoting the use of CIand
are working on integrating Jenkins with test automation frameworks
such asAvocado and OpenStack to make the process more efficient.
This presentation will cover recentdevelopments in the CI efforts
by these communities. We will also discusssome of the issues faced
(and fixed) during deployment of theinfrastructure, pitfalls of
cross-platform integration of effortsand a planned road-map and
next steps to sustain a developingenvironment for all future releases.

Gentle Introduction to Node.js (not only) for Java devs

Feedback Survey

Maybe you've already heard it - Node.js is becoming the new platform of choice in many development teams and production systems, known for its flexibility, simplicity and having a plethora of ready-to-use libraries. And many of us, (not only) Java developers, are curious what's in it that it drives so many people away (not only) from Java.

As an active Javaist & JavaScripter, Lukas can offer interesting perspective on what Node.js offers as an alternative to the mature Java ecosystem. So, tighten your seat bealts, it will be a wild ride!

In this session, Lukas will introduce Node.js and compare it with Java:

asynchronous flows / promises

functional programming in JS

parallelization

packaging

modularity

language features from ECMAScript 6 (also known as ES 2015)

differences between browser- and server-side JS

running JS on the JVM

Debugging the Virtualization Layer (libvirt and QEMU) in OpenStack

Feedback Survey

Virtualization drivers (e.g. libvirt, QEMU/KVM) are the core part of OpenStack Compute layer. An OpenStack environment is challenging to debug as is -- more so when multiple Compute nodes and thereby multiple libvirt daemons and QEMU
instances are involved. A good grasp of Virtualization debugging mechanisms is vital for effective root cause analysis. To that end, libvirt and QEMU provide a rich set of debugging controls that allow us to query (or modify) the state of virtual machines in distress.

This talk focuses on providing an in-depth view of aforementioned techniques.

Topics include: debugging Nova Compute process crashes; gathering specific patterns from libvirt log filters, libvirt environment variables, and systemd journal fields; live querying the VM (and QEMU) state through `virsh` and QEMU Machine Protocol (QMP) commands; tuning the libvirt daemon logging; monitoring events emitted by QEMU, etc. Along with a real-world example that ties together some of the techniques discussed.

Audience would include OpenStack infrastructure operators, Virtualization (libvirt/QEMU/KVM) administrators, developers, tinkerers, or any one interested in understanding the Virtualization layer in OpenStack to help equip yourself with better debugging techniques.

CentOS Infra revealed

Feedback Survey

CentOS Project exists now for more than 10 years now, and some people are wondering how the CentOS.org Infra is managed. We'll explain all the tools we use to maintain that infra, but also the constraints we have due to the fact that our infra is spread around the world on community/donated machines, without SLA and disappearing without notification. We'd like to also not only present how we run the infra, from a community perspective, but a real discussion with other distributions (round-table discussion ? ) about those common issues, and how to solve those

Freak show (#2): CTDB -- Scaling The Aliens Back To Outer Space

Feedback Survey

Samba is the well established server software implementing SMB and related Windows-protocols on Linux since almost a quarter decade now. Despite the fact that it has to follow Windows as the reference implementation of all these protocols, Samba was able to substantially raise the bar: Long before Microsoft announced SMB file server cluster with SMB 3.0 in late 2012, Samba created an all-active scale-out file server cluster when running on top of a distributed / clustered file system with the introduction of the CTDB software.

While CTDB is at its core a special purpose clustered database and messaging transport for Samba, it is also a slim little resource manager for virtual IPs and a few other services in the cluster.

This presentation describes the architecture of Samba and the history of the creation of CTDB. It demonstrates how easy one can set up a scale out Samba cluster on top of a distributed scale-out file system with the example of GlusterFS, and illustrates a few of the pleasantries that the SMB protocol brings with it in the clustered environment, such as fail over without aborting I/O by virtue of durable/persistent file handles.

Finally the current project to move towards a unified HA infrastructure for storage components is introduced.

(The talk will be co-presented with Günther Deschner (FAS: gd).)

Cython: Stop writing native Python extensions in C

Feedback Survey

Cython [1] let's you write native Python extensions in a syntax very similar to Python itself. It compiles your code to C and gives you the performance of C (or C++) while keeping the coding itself easy and Pythonistic. You can use Cython to write performance focused parts of your Python project or to create nice Python interfaces for C or C++ libraries, without the need of going mad using the Python C API.

This workshop is interned for programmers already familiar with the Python language, who have no or very small knowledge of Cython.

Live demos are part of the session - the entire session is mostly demos.

Quality Assurance Workshop

Tags workshop

Feedback Survey

SCAP is a set of specifications related to security compliance. The primary use-case is to ensure a system is configured according to a predefined policy. It is heavily used in government, defense and finance industries.

In this talk we will explore how to use SCAP in the cloud-age to do security compliance of virtual machines and containers. We will start by installing the tools and preparing the SCAP content. Then we will proceed to scan a virtual machine for compliance, further refining the content. After that we will explore how to scan containers.

In the last segment we will discuss how to get content suitable for your infrastructure. We will explore sources of content and talk about customization options.

Assemble Business Applications with BPM Back-end

Feedback Survey

Most of the new applications and start-ups use MVP (Minimum Viable Product) concept. It is very easy to work with such applications because they know exactly what we need them for and no more. In contrast there exist complex robust applications which can do everything we can think of but they are hard to learn, slow, not effective for our particular need, using too much resources, "expensive", and so on. Into this category we can put most of the business applications from big vendors which attract as many customers as possible and which need to fit to any business.

For many years, we have had flexible solutions (SOA, BPM, microservices, etc.) to keep business logic out of our applications. However, we did not have anything like that in the presentation layer and user interfaces of web applications until recently when web components emerged, html5 imports functionality was introduced, and lastly when Polymer 1.x became production ready in May 2015.

In this talk, we will get familiar with Polymer and its elements. To assemble a business application, we will create reusable custom BPM elements which will communicate to KIE Server working as a BPM back-end where we will keep all business processes, rules, forms, and other assets. Since we won't have to pay attention to the business logic, we will use the given time to focus on the user interface which end-users value the most. Like in any web application we will need routing, forms, data binding, signaling, asynchronous calls, calling REST services, hence there are many functionalities to discover.

The future of disk encryption with LUKS2

Feedback Survey

For years Fedora provides disk encryption option
in basic installer configuration. The LUKS (Linux Unified Key Setup),
implemented through cryptsetup library, provides convenient way to
configure such a basic disk-encrypted systems.

In this presentation we will focus on new requirements
for deploying disk encrypted storage in modern systems.
We will present the new LUKS2 format definition that will allow
implementation of these requirements in future.

These requirements are both technical (for example integration
to an enterprise key management systems) but also based
on new advancements in cryptographic algorithms (for example
new key-derivation functions more resistant to massive parallel
systems used by attackers for password cracking).

Another current requirement is an ability to change encryption
parameters without need of complete disk re-formatting.
We will describe prototype of a re-encryption tool that allows
such a change on a fully running system without any downtime.

Last but not least we will mention some interesting answers
from users participating on a survey questionnaire focused
on usage of disk-encryption systems.

Solving dependencies when installing new packages is a process that in some cases can be computationally very intensive. SSDS is designed to overcome this issue. Client device gathers information about installed packages and enabled repos which are then sent to a server. The server then takes care of dependency solving and the result is sent back to client device as a list of packages that are needed to proceed with the install process and without dependency solving on client.

Tactics of Code Auditor

Feedback Survey

Source Code Auditing is an important part of security. Being proactive in looking for security bugs before the software is shipped is great way to cut down the risks. Though Source Code Auditing can be performed before the code is shipped or after the code is compiled and shipped as binary. In this talk I would share some of tactics and tools that I use to perform code auditing and explain different types of vulnerabilities present in code caused by for e.g Buffer Overflows, Heap Overflows , data type, arithmetic computations and etc. Some parts of this talk would have live demo and also might go into live pentesting according to time frame.

- Introduction
- Why we need to perform source code audits
- Defining scope of audit

- SoftWare Auditing Tactics [ C/C++ ]
- Attack plan with limited time frame
- Where to attack
- How to attack
- Which tools to use
- Understanding the impact of vulnerability

Test Automation and CI using DiSTAF

Feedback Survey

DiSTAF stands for Distributed Systems Test Automation Framework. It provides powerful APIs which enables the user to automate the tests fast and efficiently. It is very modular and written with simplicity in mind. Although it is written to solve the automation problems of glusterfs, it can be used to automate many distributed systems. More information is available at https://github.com/gluster/distaf.

In the presentation I will cover the advantages it has over the other test automation frameworks and about architecture and APIs. I will also cover how the upstream CI has been structured using the distaf and containers.

I will be giving a live demo if the time permits.
