Ironic is a modern open-source tool for hardware provisioning. Combining a RESTful API, a scale-out control plane, and pluggable hardware drivers for both in- and out-of-band management, Ironic installs operating systems in a fast, efficient, and reliable fashion.
In fact, Ironic does not “install” an operating system in the traditional sense – it doesn’t use a kickstart/preseed file or an ISO image. Instead, compressed machine images are copied onto each host, and a minimal configuration (IP, host name, SSH keys) is applied at first boot. This guarantees the consistency of the initial state of each machine in a way that traditional installers do not. Bonus: it’s also faster!
With a vibrant community of developers from the most popular server hardware vendors, Ironic’s support for many of the latest and greatest management technologies is coming directly from the creators of these technologies. Meanwhile, the project’s leaders work to create a common abstraction layer that provides a consistent experience across all supported hardware. But Ironic is still a young project – it was only started in 2013 – and there is much on the roadmap.
In this session, Devananda will demonstrate how to install Ironic with Ansible, modify a cloud image for bare metal, and deploy it to a server. He will discuss the history and architecture of the project, and its current goals and challenges. Attendees should be familiar with the task of hardware provisioning and standards like PXE and IPMI, but do not need deep knowledge of related tools.

Pushing Packets - How do the ML2 Mechanism Drivers Stack UpJames Denton
Architecting a private cloud to meet the use cases of its users can be a daunting task. How do you determine which of the many L2/L3 Neutron plugins and drivers to implement? Does network performance outweigh reliability? Are overlay networks just as performant as VLAN networks? The answers to these questions will drive the appropriate technology choice.
In this presentation, we will look at many of the common drivers built around the ML2 framework, including LinuxBridge, OVS, OVS+DPDK, SR-IOV, and more, and will provide performance data to help drive decisions around selecting a technology that's right for the situation. We will discuss our experience with some of these technologies, and the pros and cons of one technology over another in a production environment.

Static Partitioning with Xen, LinuxRT, and Zephyr: A Concrete End-to-end Exam...Stefano Stabellini
Static partitioning enables multiple domains to run alongside each other with no interference. They could be running Linux, an RTOS, or another OS, and all of them have direct access to different portions of the SoC. In the last five years, the Xen community introduced several new features to make Xen-based static partitioning possible. Dom0less to start multiple static domains in parallel at boot, and Cache Coloring to minimize cache interference effects are among them. Static inter-domain communications mechanisms were introduced this year, while "ImageBuilder" has been making system-wide configurations easier. An easy-to-use complete solution is within our grasp. This talk will show the progress made on Xen static partitioning. The audience will learn to configure a realistic reference design with multiple partitions: a LinuxRT partition, a Zephyr partition, and a larger Linux partition. The presentation will show how to set up communication channels and direct hardware access for the domains. It will explain how to measure interrupt latency and use cache coloring to zero cache interference effects. The talk will include a live demo of the reference design.
This slide is just for beginner journey with docker who are eager to learn docker but don't know where to start or how it works. In here I am trying to explain every basic things of docker as simple as possible.

Launch the First Process in Linux SystemJian-Hong Pan
The session: https://coscup.org/2022/en/session/AGCMDJ
After Linux kernel boots, it will try to launch first process “init” in User Space. Then, the system begins the featured journey of the Linux distribution.
This sharing takes Busybox as the example and shows that how does Linux kernel find the “init” which directs to the Busybox. And, what will Busybox do and how to get the console. Try to make it like a simple Linux system.
Before Linux kernel launches “init” process, the file system and storage corresponding drivers/modules must be loaded to find the “init”. Besides, to mount the root file system correctly, the kernel boot command must include the root device and file system format parameters.
On the other hand, the Busybox directed from “init” is a lightweight program, but has rich functions, just like a Swiss Army Knife. So, it is usually used on the simple environment, like embedded Linux system.
This sharing will have a demo on a virtual machine first, then on the Raspberry Pi.

Ironic Towards Truly Open and Reliable, Eventually for Mission Critical
Isn’t it Ironic that a Redfish is software defining you Bruno Cornec
Ironic already helps you deploying your bare metal servers as part of your OPenStack based cloud infrastructure.
A new ongoing effort is going on between various acors to standardize server management in a software defined way using a new RESTful API called Redfish specification (WIP definition at http://www.redfishspecification.org)
We will explain our current work to create a python library to offer some interesting Redfish specification abstraction useful to Ironic (power management, information pickup, ...) and how we intend to adapt Ironic in order to add support for the Redfish specification in the future

Dieser Vortrag zeigt, welchen Herausforderungen im Hosting punkt.de in der jüngeren Vergangenheit gegenüber stand und welche Änderungen gegenüber unserer 2010 vorgestellten "NanoBSD"-Architektur wir seitdem umgesetzt haben. Der proServer hat auf der Seite des Hosting-Anbieters viele der erwünschten Eigenschaften eines "Private Cloud"-Produkts, stellt sich dem Kunden aber wie ein klassischer Root-Server dar. Für Anwendungen, bei denen eine solche Plattform gefordert ist, ein unschätzbarer Vorteil gegenüber reinen Container-Lösungen, die praktisch immer eine speziell angepasste Anwendungs-Architektur benötigen.
Running Applications on the NetBSD Rump Kernel by Justin Cormack eurobsdcon
Abstract
The NetBSD rump kernel has been developed for some years now, allowing NetBSD kernel drivers to be used unmodified in many environments, for example as userspace code. However it is only since last year that it has become possible to easily run unmodified applications on the rump kernel, initially with the rump kernel on Xen port, and then with the rumprun tools to run them in userspace on Linux, FreeBSD and NetBSD. This talk will look at how this is achieved, and look at use cases, including kernel driver development, and lightweight process virtualization.
Speaker bio
Justin Cormack has been a Unix user, developer and sysadmin since the early 1990s. He is based in London and works on open source cloud applications, Lua, and the NetBSD rump kernel project. He has been a NetBSD developer since early 2014.

Clear Containers is an Open Containers Initiative (OCI) “runtime” that launches an Intel VT-x secured hypervisor rather than a standard Linux container. An introduction of Clear Containers will be provided, followed by an overview of CNM networking plugins which have been created to enhance network connectivity using Clear Containers. More specifically, we will show demonstrations of using VPP with DPDK and SRIO-v based networks to connect Clear Containers. Pending time we will provide and walk through a hands on example of using VPP with Clear Containers.
About the speaker: Manohar Castelino is a Principal Engineer for Intel’s Open Source Technology Center. Manohar has worked on networking, network management, network processors and virtualization for over 15 years. Manohar is currently an architect and developer with the ciao (clearlinux.org/ciao) and the clear containers (https://github.com/01org/cc-oci-runtime) projects focused on networking. Manohar has spoken at many Container Meetups and internal conferences.
Identifying and Supporting 'X-compatible' Hardware BlocksChen-Yu Tsai
An SoC is comprised of multiple IP blocks from various vendors. In some cases the sources or models of these hardware blocks are not documented or marketed by the SoC vendor. Nevertheless, there are only a handful of IP vendors for a given application space. Chances are high that these undocumented blocks are compatible with or even the same as those already supported in the Linux kernel.
This talk goes through the various "X-compatible" hardware blocks we have encountered while adding mainline support for Allwinner SoCs, how we integrated support for these into existing drivers, and hopefully, how to spot them in the future. The hardware ranges from the simplest of UARTs to complicated register-obfuscated HDMI and Ethernet controllers.
We recently tested OpenIO SDS on OVH SoYouStart servers and have built a cluster of 48 ARM nodes. In this session we will discuss our experience, the performance we measured, and the bene ts of this type of solution.

Transforming Brand Perception and Boosting Profitabilityaaryangarg12
In today's digital era, the dynamics of brand perception, consumer behavior, and profitability have been profoundly reshaped by the synergy of branding, social media, and website design. This research paper investigates the transformative power of these elements in influencing how individuals perceive brands and products and how this transformation can be harnessed to drive sales and profitability for businesses.
Through an exploration of brand psychology and consumer behavior, this study sheds light on the intricate ways in which effective branding strategies, strategic social media engagement, and user-centric website design contribute to altering consumers' perceptions. We delve into the principles that underlie successful brand transformations, examining how visual identity, messaging, and storytelling can captivate and resonate with target audiences.
Methodologically, this research employs a comprehensive approach, combining qualitative and quantitative analyses. Real-world case studies illustrate the impact of branding, social media campaigns, and website redesigns on consumer perception, sales figures, and profitability. We assess the various metrics, including brand awareness, customer engagement, conversion rates, and revenue growth, to measure the effectiveness of these strategies.
The results underscore the pivotal role of cohesive branding, social media influence, and website usability in shaping positive brand perceptions, influencing consumer decisions, and ultimately bolstering sales and profitability. This paper provides actionable insights and strategic recommendations for businesses seeking to leverage branding, social media, and website design as potent tools to enhance their market position and financial success.

You could be a professional graphic designer and still make mistakes. There is always the possibility of human error. On the other hand if you’re not a designer, the chances of making some common graphic design mistakes are even higher. Because you don’t know what you don’t know. That’s where this blog comes in. To make your job easier and help you create better designs, we have put together a list of common graphic design mistakes that you need to avoid.

Key Technologies for BM Provision
•
PXE Preboot Execution Environment (PXE) is part of the Wired for Management (WfM) specification
developed by Intel and Microsoft. Booting computers via a network.
•
NBP Network Bootstrap Program (NBP) is equivalent to GRUB (GRand Unified Bootloader) or LILO
(LInux LOader) - loaders which are traditionally used in local booting. Like the boot program in a hard
drive environment, the NBP is responsible for loading the OS kernel into memory so that the OS can be
bootstrapped over a network.
•
IPMI Intelligent Platform Management Interface (IPMI) is a standardized computer system interface
used by system administrators for out-of-band management of computer systems and monitoring of
their operation.
•
DHCP Using PXE, the BIOS uses DHCP to obtain an IP address for the network interface and to
locate the server that stores the network bootstrap program (NBP).
•
TFTP Trivial File Transfer Protocol (TFTP) is a simple file transfer protocol that is generally used for
automated transfer of configuration or boot files between machines in a local environment. In a PXE
environment, TFTP is used to download NBP over the network using information from the DHCP
server.

How to use Ironic
•
Install Ironic - Try with devstack or TripleO's Devtest, it supports Ironic for long time
– http://docs.openstack.org/developer/ironic/dev/dev-quickstart.html#deploying-ironic-with-devstack
– https://wiki.openstack.org/wiki/Tuskar/Devtest
•
Setup the compute node's nova.conf
•
compute_driver = ironic.nova.virt.ironic.driver.IronicDriver
•
scheduler_host_manager = ironic.nova.scheduler.ironic_host_manager.IronicHostManager
•
Setup tftp folder and prepare pxe boot loader file
•
# cp pxelinux.0 /YOUR_TFTP_FOLDER/
•
Prepare the baremetal flavor
•
# nova flavor-create <name> <id> <ram> <disk> <vcpus>
•
# nova flavor-key baremetal set "cpu_arch"="$ARCH" "baremetal:deploy_kernel_id"="$deploy_kernel_id"
"baremetal:deploy_ramdisk_id"="$deploy_ramdisk_id"
•
Register these nodes with correct drivers
•
# ironic node-create driver=pxe_ipmitool
•
Register the ports information
•
# ironic port-create -a aa:bb:cc:dd:ee:ff -n 76305cdf-a30a-453e-bc92-b3f869a27fd8
•
Nova boot to kick off the baremetal provision
•
Check node's provision_state/power_state value
•
# ironic node-show 76305cdf-a30a-453e-bc92-b3f869a27fd8
