  • Introduction to virtio-networking and vhost-net

    In this post we have scratched the surface of the virtio-networking ecosystem, introducing you to the basic building blocks of virtualization and networking used by virtio-networking. We have briefly covered the virtio spec and the vhost protocol, reviewed the frontend and backend architecture used for implementing the virtio interface and have taken you through the vhost-net/virtio-net architecture of vhost-net (host kernel) communicating with virtio-net (guest kernel).

    A fundamental challenge we had when trying to explain things was the historical overloading of terms. As one example, virtio-net refers both to the virtio networking device implementation in the virtio specification and also to the guest kernel front end described in the vhost-net/virtio-net architecture. We attempted to address this by explaining the context of terms and using virtio-net to only describe the guest kernel frontend.

    As will be explained in later posts, there are other implementations for the virtio spec networking device based on using DPDK and different hardware offloading techniques which are all under the umbrella of the virtio-networking.

    The next two posts are intended to provide a deeper understanding of the vhost-net/virtio-net architecture. One post will be intended for architects providing a technical deep dive into the vhost-net/virtio-net and explaining how in practice the data plane and control planes are implemented. The other post intended for developers will be a hands on session including Ansible scripts to enable experimenting with the vhost-net/virtio-net architecture.

    If you prefer high level overviews we recommend you keep an eye out for the virtio-networking and DPDK introductions, to be published in the upcoming weeks.

    The concept of the intelligent enterprise serves as an aspiration, a favorable goal on their digitalization path. Various SAP solutions promise to get them there: S/4, in-memory database Hana, SAP Cloud Platform (SCP), C/4 Hana, SAP Cloud Analytics, SAP Data Hub, cloud solutions like Qualtrics or SuccessFactors, or Leonardo.

  • A guide to human communication for sysadmins

    Not too long ago, I spoke at a tech event in the Netherlands to an audience mostly made up of sysadmins. One of my topics was how sysadmins can increase the value they deliver to the organization they work for. I believe that among the most important factors for delivering value is for everyone to know the overall organization's priorities and goals, as well as the priorities and goals of the organization's development teams.

    This all sounds obvious, but in many organizations, silos almost completely block the inter-team communication needed to understand each other's priorities. Even in large organizations that pat themselves on the back for having gone full DevOps (or aspire to go full DevOps), knowledge of the priorities and goals of other teams is not ubiquitous. When I asked the couple hundred people in my audience whether they knew their development teams and what drives those teams, very few hands came up.

  • Highlights of YaST Development Sprint 83

    The summer is almost gone but, looking back, it has been pretty productive from the YaST perspective. We have fixed a lot of bugs, introduced quite interesting features to the storage layer and the network module refactoring continues to progress (more or less) as planned.

    So it is time for another sprint report. During the last two weeks, we have been basically busy squashing bugs and trying to get the network module as feature-complete as possible. But, after all, we have had also some time to improve our infrastructure and organize for the future.

  • openSUSE Tumbleweed – Review of the weeks 2019/34 & 35

Making openSUSE Multibootable USB from Ubuntu and Install It

Filed under

HowTos

Since long ago I could not make openSUSE multibootable pendrive except in single boot mode. I could not use MultiSystem nor Sundar's MultiBootUSB nor even GLIM. What's more, I could not find any easy tutorial on the net talking about making it. Fortunately, and good news for us, recently I found Aguslr's Multiboot USB (MBUSB) that is able to create it. I have tested it and as I reported few days ago I finished the installation just as perfect as other distros I had with MultiSystem. Now it's my turn to explain how I did that in 4 steps: first, create a Multiboot USB pendrive; second, copy the ISO file to USB stick; third, boot your computer to USB; and fourth, install openSUSE with it. This USB setup can accept other distros to be bootable along with openSUSE. Enjoy!

MariaDB, VLC, Plopper, Apache Packages Update in Tumbleweed

Filed under
SUSE

There have been three openSUSE Tumbleweed snapshots released this week.

The snapshots brought new versions of VLC, Apache, Plopper and an update of the Linux Kernel.

Snapshot 20190824 delivered a fix that was made to the swirl option, which produced an unexpected result, with the update of ImageMagick’s 7.0.8.61 version. Improved adaptive streaming and a fix for stuttering for low framerate videos became available in VLC 3.0.8; 13 issues, including 5 buffer overflows we fixed and 11 Common Vulnerabilities and Exposures were assigned and addressed in the media player version. More than a handful of CVEs were addressed with the apache2 2.4.41 update. One of the CVEs addressed was that of a malicious client that could perform a Denial of Services attack by flooding a connection with requests and basically never reading responses on the TCP connection. The new version also improves the balancer-manager protection against XSS/XSRF attacks from trusted users. The x86 emulation library fixed a compiler warning in the 2.4 version and the X11 RandR utility updated the geometry text file configure.ac for gitlab migration with the xrandr 1.5.1 version. The snapshot is trending at a rating of 86, according to the Tumbleweed snapshot reviewer.

Finally, I Can Make Multiboot USB of openSUSE from Ubuntu

HowTos

As you may know, my multiboot making tools were MultiSystem (since 2015), then Sundar's MultiBootUSB (2018), and recently GLIM (2019), but they all cannot work for openSUSE. Thanks to Aguslr, his program Multiboot USB (not to be confused with MultiBootUSB above) solved this problem for me! This means up to today I never managed to make openSUSE multiboot in a USB while I always managed to make other GNU/Linux distros work successfully such as Ubuntu family, Mint, Trisquel, Debian Regular, Elementary, even Fedora. In this article, I just report my success in making openSUSE Leap 15.1 multibootable USB and then installing it on a laptop. However, this article is just my report and I planned to publish tutorial on this Aguslr's Multiboot USB as soon as possible. Anyway, go ahead and happy working!

    Hardware vendor Ampere Computing with their impressive ARM servers is doing a great job on closely following their hardware's Linux performance as part of a rigorous continuous testing regiment or ensuring quality, compatibility, and stability while being fully-automated.

    Ampere Computing's Travis Lazar talked at this week's Linux Foundation events in San Diego over the importance of continuous regression testing for software and hardware development by talking about their internal workflow and software in place. Their internal system is the "Totally Automated Regression System" or TARS for short. TARS makes use of various open-source components including the Phoronix Test Suite and its vast collection of benchmarks for providing comprehensive test coverage plus Ampere's own "extensions" to the Phoronix Test Suite. TARS also incorporates the provisioning/configuration responsibilities as well as analysis of the data.

  • From ProdOps to DevOps: Surviving and thriving

    For many of us in Production Operations (ProdOps), change is the enemy. If something changes, there is now an opportunity for things that were working just fine to experience problems. It is like a game of Jenga. When will the tower fall because a seemingly minor change unbalances the whole stack of pieces? ProdOps teams hate change so much, that countless frameworks have been invented to "manage" changes; in reality, these frameworks make the procedure for effecting a change so onerous that most people give up and accept the status quo.

    Actually, that statement is a bit unfair. These frameworks are an attempt to wrap planning and consensus around production changes, thus minimizing potential downtime caused by random or rogue changes (see Why the lone wolf mentality is a sysadmin mistake).

Xfce, A Model GTK Based Desktop | Late Summer Blathering

n full disclosure, Plasma is my Desktop Environment of choice, it is very easy to customize and to make my own with very little effort. As of late, there isn’t a whole lot of customizing I do, it’s all pretty minor. A couple tweaks to the the visuals, make it dark, change some sound effects to make it more Star Trek The Next Generation, add a couple Plasmoids and set up KDE Connect. Then I am ready to go.

Since KDE 3 and later Plasma, each release adds and refines existing features, all of which seems as though they are doing so in a sustainable fashion. New releases of Plasma are always met with excitement and anticipation. I can count on new features and refinements and an overall better experience. I didn’t look anywhere else but then, Xfce wondered into my world and although slow to change has become that desktop too. Historically, Xfce has been [for me] just there, nothing particularly exciting. It has held the spot of a necessary, minimal viable desktop… but not anymore.

  • Looking towards other operating systems

    Learning a new operating system from scratch is a daunting experience for many people. Fortunately, there are a few Linux distributions that come with a Windows-like desktop environment such as a form of a star bar at the bottom. However, Windows and Linux operating on vastly different philosophies, to the way that they are organized to the way that the files are handled. Linux employs the traditional monolithic kernel and it provides a hierarchical view of the files. Because it is modular, most of the necessary drivers can be loaded and unloaded dynamically. One of the major appeals of Linux is that it is open-source, compared to Microsoft which is a closed and inaccessible environment. Windows is made for simple and out of the box use and directed toward inexperienced users, a reason why the OS has been adopted by so many people. Linux puts more emphasis on the user, who has the possibility of customizing the desktop environment to suit their needs. Windows also offer a few, but fairly limited customization options. The main reason why people avoid switching to Linux is their gaming habits. Linux is known for not playing well with most PC games. Most PC games are being developed with Windows as the main platforms with some companies providing Linux support sometime after the original release. Games that do not have a Linux release require third party compatibility applications to run Windows games. The major application that is used to play Windows games on Linux is Wine. The developers of Wine have specified that the software is not an emulator but more of a compatibility layer for Linux to run Windows programs, not just games. In the world of programming, Wine is considered a masterpiece and one of the greatest feats of open source development that allows most Windows binaries to run on Linux without relying on any of Microsoft’s dependencies. Most of the Wine resources are dedicated to running the complicated frameworks of various DirectX components. [...] Many people prefer to enjoy online gaming, especially casino games. The beauty of these games is that most are available and can be played directly in the browser. The default browser that Linux uses is Mozilla Firefox, which itself, is a powerful browser. Because online casinos are played directly in the browser, there is almost no difference between playing them on Linux and playing them in Windows. There are also casino games that can be downloaded with most of them being made to run only on Windows due to a large number of people using the OS. As mentioned before, to run most Windows software, players have the option to use WINE. However, since because playing the casinos using the browser, most people are better off sticking with that version. Many games from online roulette to poker, and other table games are available online. Almost all online casinos found online have the option to play instantly with no download required, which is why any OS that can run a browser is perfectly capable to run casino games. Linux has been around for a long time, but it was only in the last 10 years that people have started noticing the operating system becoming more friendlier and easy to learn. Besides the many desktop environments, customizability, community and growing compatibility of games, as well as more security, many have started the transition from Windows to Linux.
