Overview of this book

Fedora Linux is a free and open-source platform designed for hardware, clouds, and containers that enables software developers and community members to create custom solutions for their customers. This book is a comprehensive guide focusing on workstation configuration for the modern system administrator. The book begins by introducing you to the philosophy underlying the open-source movement, along with the unique attributes of the Fedora Project that set it apart from other Linux distributions. The chapters outline best practices and strategies for essential system administration tasks, including operating system installation, first-boot configuration, storage, and network setup. As you make progress, you’ll get to grips with the selection and usage of top applications and tools in the tech environment. The concluding chapters help you get a clear understanding of the basics of version control systems, enhanced Linux security, automation, virtualization, and containers, which are integral to modern system administration. By the end of this book, you’ll have gained the knowledge needed to optimize day-to-day tasks related to Linux-based system administration.

Virtualization with QEMU, KVM, and libvirt

Fedora Linux comes with native support for virtualization extensions. This support is provided by Kernel-based Virtual Machine (KVM) and is available as a kernel module. QEMU/KVM in combination with the Libvirt management toolkit is the standard virtualization method in Fedora Linux.

Quick Emulator (QEMU) is a full system emulator that works together with KVM and allows you to create virtual machines with hardware and peripherals.

Finally, libvirt is the API layer and allows you to manage the infrastructure – that is, create and run virtual machines. It includes a local virtual network that enables secure communication between virtual guest systems with each other and with the host. libvirt’s default configuration also allows NAT access to the public network, which is useful for virtual machines or containers that don’t have direct access to the public interface.

The following figure illustrates the QEMU/KVM architecture...
