Linux and blockchain. The two go together, like love and marriage or a horse and a carriage. Linux was created as a decentralized, open-source software that anyone can download. While it is run by a core team of developers, anyone can submit code patches and make programming upgrades to their own systems. Blockchain was created as a highly secure, decentralized method of transferring a new virtual currency known as bitcoin. It cannot be manipulated by any one individual and inherently resists any kind of control. Both Linux and blockchain are leaders in the call for the decentralization of digital resources. This book will open your eyes to the world of blockchain and the possibilities that it entails. It re-envisions the entire Internet in such a way that people are able to take control back over it in a democratic fashion. This is of crucial importance in a day when net neutrality has been repealed and threats of government censorship of information loom on the horizon. It will also show you how Linux is one of the keys to truly exploiting the possibilities of blockchain. Inside this book, you will also learn how you can use Linux to achieve your own blockchain endeavors. You can turn your Linux computer into a node or a mine. You can even use Linux to build your own blockchain! This book will give you some of the codes, tips, and tricks that you will need in order to do so. If you are ready to use Linux to make your blockchain dreams a possibility, then this book is for you! 1. Language: English. Narrator: William Bahl.

Die Kernel-based Virtual Machine (KVM) ist im Enterprise-Bereich angekommen. Die im Linux-Kernel integrierte Open-Source-Virtualisierungslösung entwickelt sich mit breiter Unterstützung stetig weiter. Dieses Buch richtet sich an Linux-Systemadministratoren, die KVM in der Praxis einsetzen wollen. Nach einer Einführung in die Grundlagen der Virtualisierung zeigt es mögliche Anwendung von KVM und der mit ihr verwobenen Komponenten. Das Buch vermittelt anhand der gängigen Enterprise-Distributionen Red Hat Enterprise Linux, SUSE Linux Enterprise Server sowie Ubuntu praxistaugliche Lösungen zu alltäglichen Aufgabenstellungen: Es beschreibt die Installation von Host- und Gastsystemen, die Werkzeuge der Libvirt-Bibliothek, die mögliche Storage-Anbindung, die Netzwerkkonfiguration, mögliche Deployment-Strategien sowie Backup-Methoden. Weiterhin wird auf die Migration bestehender physikalischer (P2V) sowie virtueller Maschinen (V2V) auf KVM eingegangen und die Live-Migration erklärt. Ein Kapitel zu Hochverfügbarkeit erläutert die Anbindung von Shared Storage und gibt einen Ausblick auf den prinzipiellen Aufbau eines Virtual System Cluster.
