  • Virtualization Management with SUSE Manager

    SUSE® Manager 4 is a best-in-class open source infrastructure management solution that lowers costs, enhances availability and reduces complexity for life-cycle management of Linux systems in large, complex and dynamic IT landscapes. You can use SUSE Manager to configure, deploy and administer thousands of Linux systems running on hypervisors, as containers, on bare metal systems, IoT devices and third-party cloud platforms. SUSE Manager also allows you to manage virtual machines (VMs).

    Virtualization is the means by which IT administrators create virtual resources, such as hardware platforms, storage devices, network resources and more. There are quite a few tools that enable the creation of virtual resources (such as Xen and KVM), but what about the management of those tools? That’s where SUSE Manager comes in.

  • Private and Air-Gap registry for openSUSE Kubic

    Sometimes there are occasions where direct internet access is not possible (proxy/offline/airgapped). Even in this setups it is possible to deploy and use Kubernetes with openSUSE Kubic and a local private registry.

    In this blog I will explain how to setup a local server which acts as private registry providing all the container images needed to deploy Kubernetes with openSUSE Kubic.

    Software can be an enabler for healers. At Red Hat, we’ve seen this first hand from customers like Boston Children’s Hospital. That venerable infirmary is using Red Hat OpenShift and Linux containers to enhance their medical capabilities, and to augment their doctors cognitive capacity.

  • Entry Server Bang For The Buck, IBM i Versus Red Hat Linux

    In last week’s issue, we did a competitive analysis of the entry, single-socket Power S914 machines running IBM i against Dell PowerEdge servers using various Intel Xeon processors as well as an AMD Epyc chip running a Windows Server and SQL Server stack from Microsoft. This week, and particularly in the wake of IBM’s recent acquisition of Red Hat, we are looking at how entry IBM i platforms rate in terms of cost and performance against X86 machines running a Linux stack and an appropriate open source relational database that has enterprise support.

    Just as a recap from last week’s story, the IBM i matchup against Windows Server systems were encouraging in that very small configurations of the Power Systems machine running IBM i were less expensive per unit of online transaction processing performance as well as per user. However, on slightly larger configurations of single socket machines, thanks mostly to the very high cost per core of the IBM i operating system and its integrated middleware and database as you move from the P05 to P10 software tiers on the Power S914, the capital outlay can get very large at list price for the Power iron, and the software gets very pricey, too. The only thing that keeps the IBM i platform in the running is the substantially higher performance per core that the Power9 chip offers on machines with four, six, or eight cores.

    Such processors are fairly modest by 2019 standards, by the way, when a high-end chip has 24, 28, 32, or now 64 cores, and even mainstream ones have 12, 16, or 18 cores. If you want to see the rationale of the hardware configurations that we ginned up for the comparisons, we suggest that you review the story from last week. Suffice it to say, we tried to get machines with roughly the same core counts and configuration across the Power and X86 machines, and generally, the X86 cores for these classes of single socket servers do a lot less work.

SUSE Continues Working On Linux Core Scheduling For Better Security

Filed under
Linux
SUSE

SUSE and other companies like DigitalOcean have been working on Linux core scheduling to make virtualization safer particularly in light of security vulnerabilities like L1TF and MDS. The core scheduling work is about ensuring different VMs don't share a HT sibling but rather only the same VM / trusted applications run on siblings of a core.

SUSE's Dario Faggioli presented at the KVM Forum 2019 at the end of October in Lyon, France. Dario's presentation covered the latest work on core-scheduling for virtualization.

    Flatpak builds available in i386, x86-64, ARM and AArch64.

  • FPgM report: 2019-44

    Here’s your report of what has happened in Fedora Program Management this week. Fedora 31 was released on Tuesday. Fedora 29 will reach end of life on 26 November.

    I have weekly office hours in #fedora-meeting-1. Drop by if you have any questions or comments about the schedule, Changes, elections, or anything else.

  • Debarshi Ray: Toolbox — A fall 2019 update

    Fedora 31 ships with cgroups v2 by default. The major blocker for cgroups v2 adoption so far was the lack of support in the various container and virtualization tools, including the Podman stack. Since Toolbox containers are just OCI containers managed with Podman, we saw some action too.

    After updating the host operating system to Fedora 31, Toolbox will try to migrate your existing containers to work with cgroups v2. Sadly, this is a somewhat complicated move, and in theory it’s possible that the migration might break some containers depending on how they were configured. So far, as per our testing, it seems that containers created by Toolbox do get smoothly migrated, so hopefully you won’t notice.

    However, if things go wrong, barring a delicate surgery on the container requiring some pretty arcane knowledge, your only option might be to do a factory reset of your local Podman installation. As factory resets go, you will lose all your existing OCI containers and images on your local system. This is a sad outcome for those unfortunate enough to encounter it. However, if you do find yourself in this quagmire then take a look at the toolbox reset command.

    Note that you need to have podman-1.6.2 and toolbox-0.0.16 for the above to work.

  • GNOME's Mutter Adds XWayland Full-Screen Games Workaround

    Thanks to Red Hat's Hans de Goede there is another optimization to GNOME's Mutter around XWayland full-screen gaming. 

    The work by the prolific Red Hat desktop developer is for X11 games that rely upon XRandR to change the resolution while also using the NET_WM_STATE_FULLSCREEN window manager hint when going into full-screen mode. 

    [...]

    The Mutter change can be found here while the xorg-server/XWayland side change was merged in October and will be present in whenever the next X.Org Server release finally materializes.

  • How to Keep Customers Happy and Liking Us a Lot, part 1

    We’re all here for various reasons, such as paychecks, a love of great open source software, creativity, wanting to build cool products to help people, nice offices full of colleagues and treats…whatever our reasons, SUSE exists as a business to sell enterprise open source software. Or, perhaps more accurately, to build great open source software and sell first-rate services and support.
    It is very difficult to build a successful business on open source software. It’s like the restaurant business: there is no secret sauce, no magic, no lock-in. Restaurants use the same food and recipes that anyone can use. What they’re really selling is a good experience for the customer: good food, good service, pleasant atmosphere, convenience. Anyone can open a restaurant, just like anyone can launch a new open source software project, so there is a lot of competition. Restaurants have very high rates of failure. Just like restaurants, to succeed as a commercial open source business you have to be better: much, much better. You can’t rely on lock-in and scary restrictive contracts like the closed-source proprietary software companies do.

Tumbleweed Gets New OpenSSH Major Version

Filed under
Security
SUSE

Snapshot 20191027, brought an update to KDE Plasma 5.17.1. The bugfix update fixed the Mouse KCM acceleration profile on X11 on the Plasma Desktop and had a fix for KWIN with visibility of the Context Help button. Part of the update to Plasma 5.17.1 came in the 20191022 snapshot on the day of the release from the KDE Project. The kcalendarcore package was update to KDE Frameworks 5.63.0, which landed in last week’s snapshots. Quite a few YaST packages arrived in the snapshot as well; some of the those YaST packages adapted to new Keyboard handling. The other two packages updated in the snapshot were to the AV1 decoder dav1d 0.5.1, which fixed a build issue in ARM64 assembly if debug info was enabled, and desktop calculator, qalculate 3.5.0, which had a fix for steradian conversion that is related to the surface area of a sphere. The Tumbleweed snapshot reviewer is being fixed and doesn’t have a rating for the snapshot.

Seven packages arrived in the 20191025 snapshot and the openssh 8.1 was a major upgrade. The new major version added some new features like an experimental lightweight signature and verification ability. According to the changelog, “signatures may be made using regular ssh keys held on disk or stored in a ssh-agent and verified against an authorized_keys-like list of allowed keys. Signatures embed a namespace that prevents confusion and attacks between different usage domains (e.g. files vs email).” The VirtualBox hypervisor for x86 virtualization had a minor update to version 6.0.14; the maintenance release fixed potential issue in the networking with interrupt signalling for network adapters in UEFI guests. The Network Time Protocol package chrony 3.5 added support for hardware timestamping on interfaces with read-only timestamping configuration and Persistent Memory programming package pmdk 1.7 introduced two new Application Program Interface (APIs) in librpmem and libpmemobj.

Snapshot 20191018 provided minor updates for both Mozilla Firefox 69.0.3 and Thunderbird 68.1.2. The update to Firefox fixed a bug that prompted Yahoo mail users to download files when clicking on emails and the Thunderbird update fixed some glitches and fixed the address book import from a CSV. GNOME software updated to version 3.34,which could be the version that will come in openSUSE Leap 15.2. GNOME’s Thessaloniki release includes visual refreshes for a number of applications and the background selection settings also received a redesign, making it easier to select custom backgrounds. Developers using GNOME 3.34 will notices more data sources in Sysprof that make performance profiling of applications easier. Improvements to Builder include an integrated D-Bus inspector. Javascript bindings for GNOME were also updated with the gjs 1.58.1 version and gtk3 3.24.12 fixed a pointer offsets under X11 and Wayland. Python2 runtime support was removed with the updated of the samba 4.11.0 package; python 3.4 or later is required.

Also in the 20191018 snapshot was an update for the new programing language vala 0.46.3 that focuses on GNOME developers had multiple additions to the package. Programing language ruby 2.6.5 fixed a code injection vulnerability along with three other Common Vulnerabilities and Exposures. openSUSE’s snapper 0.8.5 package updated to allow trailing comments in configuration files. The Linux Kernel updated to 5.3.6. NetworkManager 1.18.4 improved the handling of externally added policy routing rules and for rules that are taken over after a restart of a NetworkManager service. The NetworkManager-applet 1.8.24 package added support for SAE authentication (WPA3 Personal). Fix regression fixes were made in both the 2.62.1 versions of glib2 and glib-networking; the latter also made two memory leak fixes. Other noteworthy packages that were updated in the snapshot were webkit2gtk3 2.26.1, libsoup 2.68.2, grilo 0.3.10, and dconf 0.34.0. The snapshot is trending at a stable rating of 92, according to the Tumbleweed snapshot reviewer.

  • Monitoring Bandwidth On Linux: Top 5 Tools in 2019

    Don’t we all wish our networks had infinite bandwidth? The reality is, however, that it is often a severely limited resource. Add to that the fact that bandwidth over-utilization can have huge impacts on network performance and we have a recipe for disaster. The solution: set up some bandwidth monitoring system. A lot of them are available. Most of them run on Windows, though, and if your OS of choice it Linux, your options are slightly more limited. You still have plenty of options, however, and we’re about to introduce the best tools for bandwidth monitoring on Linux. We’ll begin by introducing bandwidth monitoring and explain what it is. Next, we’ll cover the ins and outs of the Simple Network Management Protocol, or SNMP, one of the most-used monitoring technology. Our next order of business will be to have a look a Linux as an operating system but, more specifically, as a platform for monitoring tools. And finally, we’ll briefly review some of the best tools for bandwidth monitoring on Linux and describe their best features.

  • Molly de Blanc: Rebellion

    We spend a lot of time focusing on the epic side of free software and user freedom: joys come from providing encrypted communication options to journalists and political dissidents; losses are when IoT devices are used to victimize and abuse. I think a lot about the little ways technology interacts with our lives, the threats to or successes for user freedom we encounter in regular situations that anyone can find themselves able to understand: sexting with a secure app, sharing DRM-free piece of media, or having your communications listened to by a “home assistant.” When I was writing a talk about ethics and IoT, I was looking for these small examples of the threats posed by smart doorbells. False arrests and racial profiling, deals with law enforcement to monitor neighborhoods, the digital panopticon — these are big deals. I remembered something I read about kids giving their neighbor a pair of slippers for Christmas. This sort of anonymous gift giving becomes impossible when your front door is constantly being monitored. People laughed when I shared this idea with them — that we’re really losing something by giving up the opportunity to anonymously leave presents. We are also giving up what my roommate calls “benign acts of rebellion.” From one perspective, making it harder for teenagers to sneak out at night is a good thing. Keeping better tabs on your kids and where they are is a safety issue. Being able to monitor what they do on their computer can prevent descent into objectively bad communities and behavior patterns, but it can also prevent someone from participating in the cultural coming of age narratives that help define who we are as a society and give us points of connection across generations.

  • The Relationship Between Open Source Software and Standard Setting

    Standards and open source development are both processes widely adopted in the ICT industry to develop innovative technologies and drive their adoption in the market. Innovators and policy makers assume that a closer collaboration between standards and open source software development would be mutually beneficial. The interaction between the two is however not yet fully understood, especially with regard to how the intellectual property regimes applied by these organisations influence their ability and motivation to cooperate. This study provides a comprehensive analysis of the interaction between standard development organisations (SDOs) and open source software (OSS) communities. The analysis is based on 20 case studies, a survey of stakeholders involved in SDOs and OSS communities, an expert workshop, and a comprehensive review of the literature. In the analysis, we differentiate according to the governance of SDOs and OSS communities, but also considering the involved stakeholders and subject matter. We discuss the preconditions, forms and impacts of collaboration, before we eventually focus on the complementarity of the different Intellectual Property Right (IPR) regimes. Finally, we derive policy recommendations addressing SDOs, OSS communities and policy makers.

    Systems performance is an effective discipline for performance analysis and tuning, and can help you find performance wins for your applications and the kernel. However, most of us are not performance or kernel engineers, and have limited time to study this topic. This talk summarizes the topic for everyone, touring six important areas of Linux systems performance: observability tools, methodologies, benchmarking, profiling, tracing, and tuning. Included are recipes for Linux performance analysis and tuning (using vmstat, mpstat, iostat, etc), overviews of complex areas including profiling (perf_events) and tracing (Ftrace, bcc/BPF, and bpftrace/BPF), and much advice about what is and isn't important to learn. This talk is aimed at everyone: developers, operations, sysadmins, etc, and in any environment running Linux, bare metal or the cloud.
