Description RHOS Integration 2013-12-12 13:39:39 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/volume-affinity-weighter-function.

Description:

To reduce latency it may be desired to try to place an instance on a host which contains a volume assosiated with this instance. This can be done implicitly with a specific weighter function enabled, which takes into account volume affinity. This will result in an instance scheduled anyway whether the host with the volume was available or not.
