QEMU 6.0 Released With AMD SEV-ES Encrypted Guest Support, Experimental Multi-Process

Filed under

QEMU 6.0 is out today as the newest feature release for this processor/machine emulator and virtualizer that serves as an important part of the open-source Linux virtualization stack.

QEMU 6.0 brings with it many new features including the likes of experimental multi-process device emulation support, AMD SEV-ES encrypted guest support, new processor.machine support, and other virtualization improvements.

- QEMU can now be built with link-time optimizations (LTO) and also supports LLVM Control-Flow Integrity (CFI) too.

QEMU 6.0.0 released

  • QEMU 6.0.0 released

    Version 6.0.0 of the QEMU hardware emulator is out. "This release contains 3300+ commits from 268 authors." This release includes a lot of new emulations; see the announcement for a short list or the changelog for details.

QEMU 6.0.0 Released With Focus On ARM And RISC-V

  • QEMU 6.0.0 Released With Focus On ARM And RISC-V

    The latest QEMU version brings virtiofs performance improvements with new USE_KILLPRIV_V2 guest feature.

    Qemu is a machine emulator that can run operating systems and programs for one machine on a different machine. Mostly it is not used as emulator but as virtualizer in collaboration with KVM kernel components. In that case it utilizes the virtualization technology of the hardware to virtualize guests.

    QEMU can run independently, but due to the emulation being performed entirely in software it is extremely slow. To overcome this, QEMU allows you to use KVM as an accelerator so that the physical CPU virtualization extensions can be used.

QEMU 6.0 Is Released With A Long List Of New Features

  • QEMU 6.0 Is Released With A Long List Of New Features

    QEMU 6.0 is a huge release with a very long list of improvements for everyone using this powerful multi-platform full system emulator to run operating systems for Arm, PowerPC, RISC-V, s390, SPARC, x86 and other systems QEMU supports on Linux, Windows or macOS.


    The above list of new features in QEMU 6.0 barely scratches the surface, the full QEMU 6.0 changelog is a very long read.

    The QEMU download page for Linux does not list any AppImage, Snap, .deb or .rpm packages or binaries of any kind, it simply lists instructions for installing it using the major Linux distributions repositories. All of them have some recently new QEMU version like 5.2, none have the latest 6.0 release. That leaves compiling from source as the only option if you really want QEMU 6.0 now. The source is a 102 MiB tarball that extracts to 724 MiB. Building it is, in theory, as easy as ./configure && make, but there are a lot of optional dependencies to work out. You will likely need to install a number of development packages and a number of ./configure flags like --enable-kvm (kind of important if you want to run x86-64 software on x86-64 without a huge performance penalty). You may be better off waiting until your distribution makes a QEMU 6.0 package unless you really want one of the new features right now. The actual compile will only take about 15 minutes on a Ryzen 1600X with -j 12, even thought the source tree is huge, so it is doable. Make sure to get all the dependencies in place and re-run ./configure so you don't end up with a crippled QEMU if you decide to go that route.

    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.
