This document discusses the development of a Nova proxy driver for Red Hat Enterprise Virtualization Manager (RHEV-M) and oVirt. The driver allows OpenStack to manage virtual machines running on RHEV-M and oVirt by mapping Nova functions like boot, delete, and reboot to operations in RHEV-M like creating, shutting down, and removing virtual machines. It also maps Glance functions to managing virtual machine templates. The driver architecture, implemented functions, demonstration setup, next steps, and acknowledgements are covered in the document.
