Unified Images
Allow Nova to build instances directly from VHDs, with the customer data and kernel in one image. XS-Snapshots are already created as VHDs; this blueprint will allow Nova to boot the snapshots.

Whiteboard
What is the difference between this and raw-disk-images? Thanks, Ewan Mellor.
Ewan, Our goal is to be able to boot a VHD with kernel, ramdisk and data integrated into it. Our images will be prebuilt ahead of time with partitioning and OS preinstalled and then on boot will configured by agent rather than having information injected. Currently, we're can't upload a VHD into glance and boot from that as it requires the images to be generated in RAW image format. We can't assume we can always write into the VHD image (encrypted) which is one of the reasons for the agent. - Antony Messerli
