  • AMD SEV/SEV-ES Local Migration Support Patches For Linux - Phoronix

    Google engineers have prepared a set of Linux kernel patches allowing for AMD Secure Encrypted Virtualization (SEV) / SEV-ES encrypted state to allow for local migration support of these encrypted virtual machines on the same host.

    Local migration of VMs allow for moving the guest to a new user-space VMM within the same host such as when upgrading/changing its resources or other alterations to the virtual machine but short of remote migration to a different host.

  • A very successful first KernelCI hackfest

    Last week, Nicolas wrote about KernelCI's newly added ability to detect regressions on the Linux kernel that can directly affect camera. This new test was one of many that was written during the recent KernelCI hackfest, which took place from May 27 to June 4. Initiated as a joint effort by the Google Chrome OS team and Collabora, it was a public event with engineers and developers from different communities in attendance.

    What led to the KernelCI hackfest?

    KernelCI is community-led test system focused on the upstream Linux kernel. While following mainline and LTS branches is the best way to maintain stability and security, there are numerous products in a wide variety of industry segments that run on their own versions of Linux with their own, custom changes. Several members of the KernelCI Linux Foundation project make such Linux-based products and rely on testing upstream, as every issue caught is something they won't have to fix in their downstream, Linux-based products. In fact, over time, the more these issues are fixed, the closer it brings their products to the upstream kernel.

    One such member is Google, and their Chrome OS products. There are an increasing number of Chromebook devices in KernelCI (mostly located in Collabora's lab) which can be used to test upstream kernels, and in particular stable kernels, which are working quite well on this hardware. They are currently running all the regular tests that other platforms also use, such as LTP, kselftest, igt, v4l2-compliance, etc. As a member company, Google wanted to extend coverage with additional tests that are only currently available within Chrome OS. Hence, Google encouraged the KernelCI community to hold a hackfest to write tests.

  • Linux Foundation Makes Available Software Manifest Tool - DevOps.com

    The Linux Foundation is making available a set of free tools for building software bills of material (SBOMs) based on the software data package exchange (SPDX) file format it curates.

    Backed by more than 20 organizations, SPDX is an effort to standardize the way metadata describing the contents of a software package is described.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
