OpenStack Compute (nova)

Specifying metadata/capabilities preferences

Registered by justinsb

When API clients request a compute node or a volume, currently they can only specify the availability zone. As we support more sophisticated deployment environments, we should offer clients the ability to request more fine-grained functionality. For example, a compute node might specify that it needs a video card with GPU functionality, or a volume might be better as RAID-5 or RAID-1, or we might want a compute node as close as possible to a particular volume etc. If clients provide their preferences using metadata tags, the schedulers can then match these requests to available resources.
