This document summarizes enhancements being made to the VMware Nova Compute Driver. It outlines key areas for improvement like launching OVF disk images, VNC console support, attaching/detaching iSCSI volumes, guest info, host operations, VLAN support, live and cold migration. It then provides details on specific driver enhancements like supporting sparse/streamOptimized disks, power on/off, getting VNC console, injecting network info, volume attachment/detachment, host resource info, and live migration functions. The document also discusses linked clones, custom image properties in Glance for VMware adapter/disk types and guest OS, and VNC configuration flags. Lastly, it includes a diagram showing the relationship between
