Each time, he introduces the subject and covers most of the configuration details with lots of explanations. Because the topics are pretty new, the quality is lower. If the introduction is still good, some chapters lack real technical material besides a basic tutorial. The iScsi chapter needs a rewriting. But, if you are mainly interested in a RHCE book, there are arguably better options. Despite the proofreading job done, the first edition of this book displayed a lot of typos.
Also, a major command to deal with disks, lsblk, is even not mentioned. The RHCE part of the book provides a good coverage of the different objectives. Globally, the book is a real success and should satisfy most of the readers. When that changes, ask for a book update a second edition should come by the end of June If one of the previously mentioned topics interests you,the book will bring you clear and progressive explanations.
Also, choices made in the book are sometimes difficult to understand: good coverage of Xfs troubleshooting but nothing about Ext4! Good explanation about moving a user from one group to another but nothing about the ability for a user to get an additional group! However, besides these little imperfections, this book is full of useful tips that every system administrator should know to get his job done and explores rarely discussed topics rpmdb recovery, MariaDB password recovery, Tripwire installation, Auditd, etc successfully.
The first edition of the book covered RHEL 6. The second edition has recently been updated with good RHEL 7 material. Many other recipes covering production subjects are also addressed like the deployment with PXE, the network configuration of servers, SELinux, or the management of Yum repositories.
However, the chapters about Systemd or Firewalld are less convincing. If deployment of RHEL 7 production servers is the core of your job, this book will definitively help you. Before, you could find some information on Internet libvirt. Here, the authors, all working for Red Hat, explore the theory behind the virtualization and present some KVM internals. Then, they address many facets like network, storage, live migration and snapshot, giving many examples on each topic.
They delve into OpenvSwitch, showing the advantages over the basic Linux bridge. Finally, they introduce oVirt, discuss OpenStack deployment, performance tuning and best practices. If you really want to get a good understanding of KVM, you need this book.
