Virtual sources are information such as ideas, plans, design, intellect, software, video, audio, genetics, etc. which must be stored and expressed by physical space, time, mass and energy.
Design is important, but it is just one half of the sources required for production.
Design can be thought of as the VIRTUAL Sources of Production. Virtual sources are infinite in theoretic potential and include things such as ideas, plans, mechanical design, genetics, text, audio, video, software. I am not talking about any particular copy of any of these things, but the *pattern* of those things. What I mean by 'pattern' here is the information describing any single instance of those things, but NOT any particular instance.
Physical Sources are the other half of every thing. To "instantiate" any Virtual Source requires the Physical Sources of Space, Time, Mass and Energy.
The genetics of an apple are "instantiated" by the organism itself as a seed and then tree uses land, time, soil, water, sun, and other rotting organisms to grow.
The mechanical design of a CEB machine is not worth anything until someone creates an instance of it using land, time, machines, steel, plastic, grease, electricity, fuel, etc.
Because of their inescapable connection to physical sources, virtual things can never actually be copied for zero cost. Even across the internet there are costs for both the server and the client such as: bandwidth, slightly higher electricity to run the NIC, more CPU time to run the kernel module that controls the NIC, the usermode applications that serve and receive the data, RAM dedicated to that process and Hard Drive space needed to store the new copy. There is also the 'cost' of the exclusivity of those physical resources to that data and activity during those time slices. This may seem an unrealistic academic exercise, but it really isn't if we scale the problem toward the upper extreme. Imagine these costs for YouTube.com, Video.Google.com, etc. when they are servicing millions of customers. It is a very big deal indeed and requires huge rooms with expensive cooling equipment (I once read the cooling is commonly more expensive than the electricity for the computers).

BitVisor.org >>BitVisor is a tiny hypervisor (Virtual Machine Monitor) for enhancing the security of desktop computers. It can be used as a basis for implementing various security services, such as mandantory encryption of storage and networks, intrusion detection, access control, and so on, by providing a facility for security modules in the hypervisor to intercept and manipulate I/O access from the guest OS.
Ganeti.GoogleCode.com >>Ganeti is a cluster virtual server management software tool built on top of existing virtualization technologies such as Xen or KVM and other Open Source software. Ganeti requires pre-installed virtualization software on your servers in order to function. Once installed, the tool will take over the management part of the virtual instances (Xen DomU), e.g. disk creation management, operating system installation for these instances (in co-operation with OS-specific install scripts), and startup, shutdown, failover between physical systems. It has been designed to facilitate cluster management of virtual servers and to provide fast and simple recovery after physical failures using commodity hardware.
TheVesi.org >>The goal of the Vizioncore Virtualization EcoShell is to provide a freeware desktop application for novice and expert IT administrators leveraging Windows PowerShell scripts across their multi-platform virtual environments. Fostered and supported by The Virtualization EcoShell Initiative (VESI) - an online community-driven Web site sponsored by Vizioncore - the Virtualization EcoShell is enhanced by the participation of community members through the exchange of new ideas, value-add services and extendable scripts.

Virt-Manager.org >>The "Virtual Machine Manager" application (virt-manager for short package name) is a desktop user interface for managing virtual machines. It presents a summary view of running domains, their live performance & resource utilization statistics. The detailed view graphs performance & utilization over time. Wizards enable the creation of new domains, and configuration & adjustment of a domain's resource allocation & virtual hardware. An embedded VNC client viewer presents a full graphical console to the guest domain.
