About the Author
Rik Goldman had 18 years of professional IT experience and 17 years of teaching experience when he became the director of technology and a teacher of advanced computing at Chelsea School in 2012.
Throughout his 10 years at the university, he concentrated on literary computing, new media, humanities computing, and virtuality. At first, Rik supported his studies by developing institutional websites and database applications; eventually, however, he became the administrator of Solaris and Irix servers for West Virginia University's Center for Literary Computing, a lab committed to the study of electronic texts, virtuality, and digital composition and rhetoric.
In the classroom, Rik's commitment to authentic teaching and learning as well as his advocacy of social justice and equity have placed him at the vanguard of technology education. Working with and learning from his students, he has overseen projects that have provided real solutions for school infrastructure, data management, and programming. His many accomplishments reveal an educator who strives to provide authentic opportunities for learning and engagement, but his true legacy lies in what he has engendered in his students: a desire for knowledge, a critical urge, and an analyst's zeal for complex abstractions. Through this work with students and his responsibilities as a systems administrator, Rik has enjoyed a productive preoccupation with virtualization technologies and their impact on popular culture.
Since his full-time adoption of Red Hat 5 at home, he has been committed to GNU/Linux and the underlying philosophies that have made it so successful. Consequently, he is a passionate advocate of open source and free software. Together with his students, he has contributed to the success of a myriad open source endeavors by developing documentation, writing code, and mentoring communities of young developers from around the world.
In his free time, Rik enjoys reading literature, exploring critical theory, listening to records, and traveling to concerts with his family.
Acknowledgments
This book could not have been realized without the kind patience, understanding, and encouragement of Sabre Goldman and our remarkable son, Ender Ripley. Whatever fantastic adventures I dream of, it's through Sabre's unflagging support and enduring patience that those impossible dreams are realized.
The importance that my mother places on the power of words, text, and narrative continues to influence my life's trajectory and always propels me toward opportunities to find the right word. Without her, I wouldn't have had the interest or skills to pursue this opportunity.
Thanks to the Chelsea School community, particularly my colleagues and students, without whom there's no me. I am lucky to be a part of a community that never fails to inspire me to learn, develop, share, and improve.
My sincerest thanks go out to Tim Bielawa, the author of The Linux Sysadmin’s Guide to Virtual Disks. By posting a public draft of his work in progress, he did this project significant good. Cheers to Tim and so many others who contribute documentation of open source projects.

Preface
"There is a double spooking the world, the double of abstraction. The fortunes of states and armies, companies and communities depend on it. All contending classes - the landlords and farmers, the workers and capitalists - revere yet fear the relentless abstraction of the world on which their fortunes yet depend. All the classes but one. The hacker class."
"The virtual is the true domain of the hacker. It is from the virtual that the hacker produces ever-new expressions of the actual. To the hacker, what is represented as being real is always partial, limited, perhaps even false. To the hacker there is always a surplus of possibility expressed in what is actual, the surplus of the virtual. This is the inexhaustible domain of what is real without being actual, what is not but which may be. To hack is to release the virtual into the actual, to express the difference of the real."
--McKenzie Wark, A Hacker ManifestoNot so many years ago, it would've taken three computers to author this book efficiently on the go. Virtualization, however, has made it possible to write without the obscene hassle of dragging about so much baggage. Virtualization has reduced labor and energy expenditure and maximized productivity and discretionary time during the writing and production of this book.
Abstraction liberates us from material constraints, leaving in their place the privilege of nostalgia—tractor-fed edge strips, darkroom chemicals, printing presses and type-set trays, overflowing money bags with dollar signs, and of course, cramped server rooms.
Through server virtualization, the abstraction of computing resources from physical systems has overturned data centers and radically upset the traditional and repetitive routines of system engineers and administrators in favor of efficiency, conservation, lowered expenditure, secure systems, and the simple deployment of automation to complete repetitive tasks.
Proxmox VE has been a pioneering agent in this rapid revolution since the 2008 release of version 1.0—the first hypervisor to support both virtual machines and containers.
With version 4.2 in the works, and the industry's fascination finally fixed on the realization of a container revolution, Proxmox VE still provides an open source, enterprise virtualization solution with premium support that enjoys tremendous international popularity—even as competing brands have scrambled to roll out container solutions just in time.
This book is packed with introductory concepts and best practice techniques for experienced Linux users eager to take advantage of bleeding edge virtualization strategies and practices with Proxmox VE.
This book explores the benefits of two of these complementary virtualization technologies, containers and virtual machines, so you'll be forearmed to make informed and deliberated choices regarding the best paths for virtualizing your data center.
What this book covers
Chapter 1, Proxmox VE Fundamentals, outlines Proxmox VE's features and distinguishing characteristics and briefly compares and contrasts virtual machines and containers.
Chapter 2, Installing Proxmox VE, goes through the Proxmox VE installation process after covering Proxmox VE's hardware requirements and discussing minimal and optimal hardware specifications.
Chapter 3, Creating Containers, starts with a primer on containers and their uses before providing a walkthrough of the container creation processes, including choosing and downloading an OS or virtual appliance template.
Chapter 4, Creating Virtual Machines, first elaborates on the functional differences between virtual machines and suggests prospective use cases and the inherent benefits and drawbacks of full virtualization. It then walks through the process of creating and configuring virtual machines intended for Microsoft Windows Server and Fedora Server.
Chapter 5, Working with Virtual Disks, compares and contrasts virtual hard disk options, including disk image types, virtual bus/interfaces, and cache types.
Chapter 6, Networking with Proxmox VE, contrasts common virtual Ethernet adaptor options provided by Proxmox VE and works to articulate use cases for each.
Chapter 7, Securing Proxmox VE, enumerates strategies for mitigating security threats to virtualized datacenters in general, and Proxmox VE hosts and guests in particular.
What you need for this book
Working with the illustrative examples in this book will require a 64-bit machine to host Proxmox 4.1 that meets at least the minimum recommended specs for evaluation:
This is not an ideal rig—more powerful specs can be found in Chapter 2, Installing Proxmox VE.
In addition to a machine to host Proxmox VE, broadband internet access is assumed, as is a remote workstation on the same LAN as the Proxmox VE host, a modern, JavaScript-enabled web browser, and installed ssh and sftp clients.

Chapter 1. Proxmox VE Fundamentals
Proxmox Virtual Environment (PVE) is a mature, complete, well-supported, enterprise-class virtualization environment for servers. It is an open source tool—based in the Debian GNU/Linux distribution—that manages containers, virtual machines, storage, virtualized networks, and high-availability clustering through a well-designed, web-based interface or via the command-line interface.
Note
Developers provided the first stable release of Proxmox VE in 2008; four years and eight point releases later, ZDNet's Ken Hess boldly, but quite sensibly, declared Proxmox VE as Proxmox: The Ultimate Hypervisor (http://www.zdnet.com/article/proxmox-the-ultimate-hypervisor/).Four years later, PVE is on version 4.1, in use by at least 90,000 hosts, and more than 500 commercial customers in 140 countries; the web-based administrative interface itself is translated into 19 languages.
This chapter explores the fundamental technologies underlying PVE's hypervisor features: LXC, KVM, and QEMU. To do so, we will develop a working understanding of virtual machines, containers, and their appropriate use.
We will cover the following topics in this chapter:
Proxmox VE in brief
With Proxmox VE, Proxmox Server Solutions GmbH (https://www.proxmox.com/en/about) provides us with an enterprise-ready, open source type 2 Hypervisor. Later, you'll find some of the features that make Proxmox VE such a strong enterprise candidate.
