here are plenty of guides out there for making ethernet bridges in Linux to support virtual machines using built-in network scripts or NetworkManager. I decided to try my hand with creating a bridge using only systemd-networkd and it was surprisingly easy.
First off, you’ll need a version of systemd with networkd support. Fedora 20 and 21 will work just fine. RHEL/CentOS 7 and Arch Linux should also work. Much of the networkd support has been in systemd for quite a while, but if you’re looking for fancier network settings, like bonding, you’ll want at least systemd 216.

Space is a simple virtualization control panel written in Python with Flask. Space utilizes the libvirt API to interact directly with the hypervisor, and thus (will eventually) support all virtualization technology that libvirt supports.
This project is still in a relatively early stage of development, it is feature complete but there is still a fair amount of work to be done. With that being said, use at your own risk!

As invaluable tools in networked and distributed systems research, network emulators offer a viable alternative to live experimental / testbed networks. We are developing a realistic network topology emulation / simulation framework based on the FreeBSD operating system kernel partitioned into multiple lightweight virtual nodes, which can be interconnected via kernel-level links to form arbitrarily complex network topologies. The concept of using virtual nodes inside a kernel for fast network emulation is not entirely new, yet previously published work generally advocated the implementation of kernel-level virtual nodes with capabilities limited to only certain simple functions, such as passing of network frames from one queue to another based on a static precomputed path. We are basing our work on a thesis that virtual nodes, which could offer the identical rich set of capabilities as the standard kernel does, can be implemented very efficiently by reusing the existing OS kernel code. Our model therefore not only provides each node with an independent replica of the entire standard network stack, thus enabling highly realistic and detailed emulation of network routers; it also enables each virtual node to run a private copy of any unmodified user-level application, including routing protocol daemons, traffic generators, analyzers, or application servers. Furthermore, in later development phases we expect to enable each virtual node to support multiple network protocols concurrently, such as both IPv4 and IPv6, which would bring us a step closer to allowing for emulation of true multiprotocol networked environments.
Packer is a tool for creating identical machine images for multiple platforms from a single source configuration.
Packer is easy to use and automates the creation of any type of machine image. It embraces modern configuration management by encouraging you to use automated scripts to install and configure the software within your Packer-made images. Packer brings machine images into the modern age, unlocking untapped potential and opening new opportunities.
It's with great pleasure that the LXC team is announcing the release of LXC 1.0!
This release is a significant milestone for us as it marks the first release we consider to be production ready. It features a wide variety of improvements to container security, a consistent set of tools, updated documentation and an API with multiple bindings.
Virtualization allows the creation of multiple virtual machines (VM) on top of an existing computer, each VM configured in a very specific way. All virtual machines run in parallel alongside the regular host applications, without affecting the host system. The type of virtualization I am currently using is Linux containers (LXC), a lightweight virtualization technology built into Linux kernel.

Dans l'environnement tetaneutral.net un adhérent a le choix d'utiliser plusieurs IPv4 publiques et un bridge avec son interface pour virtualiser mais ceci consomme plusieurs IPv4 publiques.
VNX is a general purpose open-source virtualization tool designed to help building virtual network testbeds automatically. It allows the definition and automatic deployment of network scenarios made of virtual machines of different types (Linux, Windows, FreeBSD, Olive or Dynamips routers, etc) interconnected following a user-defined topology, possibly connected to external networks
