virt-factory

Virt-Factory is a framework for managing a large number of Xen virtual machines, such as might be found in data centers or large lab configurations. It works by managing a pool of registered physical hosts and then deploying virtual machines, which have specific roles as defined by their "profiles" (profiles act as shareable virtual appliance definitions), onto those hosts. Virt-Factory provides both a Web UI (for ease of use) and an XML-RPC API (for scripting of admin actions). A command line interface (along with other advanced batch management features) is coming soon.
