Hi, Based on the discussions we have had in the past few scheduler sub-team meetings, I am sharing a document that proposes an updated Instance Group Model and API extension model. This is a work-in-progress draft version, but sharing it for early feedback. https://docs.google.com/document/d/17OIiBoIavih-1y4zzK0oXyI66529f-7JTCVj-BcXURA/edit?usp=sharing This model support generic instance types, where an instance can represent a virtual node of any resource type. But in the context of Nova, an instance refers to the VM instance. This builds on the existing proposal for Instance Group Extension as documented here in this blueprint: https://blueprints.launchpad.net/nova/+spec/instance-group-api-extension Thanks, Yathi. -------------- next part -------------- An HTML attachment was scrubbed...
