NiftyName is a system for creating and managing virtual machine pools and all related components such as storage, private and public networks. It is intended to be used as a free alternative to Amazon EC2 and Microsoft Azure. All components have been designed for multi-site active redundancy, though this is not supported yet. Its architecture is based on documented XML-RPC (SSL) Web services, so you can make your own derivative tools for it. Console and GTK+ client applications are provided. VMs are based on KVM. It supports IPv6, private VLANs, multiple interfaces, user/client management, permissions, and roles.
OpenNode is a server virtualization solution that provides an easy-to-use (CentOS/RHEL based) bare-metal ISO installer that supports both OpenVZ container-based and KVM full virtualization technology on the same host. The OpenNode ISO installer will set up a minimal CentOS server system with the following features: a RHEL kernel (provided by OpenVZ project) modified to support both openvz and kvm virtualization, libvirt management interface support for openvz and kvm hypervisors, func (https://fedorahosted.org/func/) client support for central management purposes, and VM template downloads provided by the opennode TUI utility.
WebVirtMgr is a libvirt-based Web interface for managing virtual machines. It allows you to create and configure new domains, and adjust a domain's resource allocation. A VNC viewer over a SSH tunnel presents a full graphical console to the guest domain. KVM is currently the only hypervisor supported.
Q-Tubes is a Web-based QEMU/KVM machine manager in Python built around the Pyramid Web framework. Its goal is to allow management of QEMU/KVM networks across single host instances, and ultimately across server farms. It supports minimal VM instances with disk support and basic network configuration (no user-space network yet), and basic VDE switch configurations. It provides a WSGI interface for deployment behind WSGI-aware servers, or provides its own basic server (python-waitress) for simple instances. The application is under steady development and has a moderate number of (Python) dependencies. Installation in a virtualenv is strongly recommended. It requires QEMU/KVM, VDE, and Python 2.7 or later.
