Ganeti 2.1 design

This document describes the major changes in Ganeti 2.1 compared to the 2.0 version.

The 2.1 version will be a relatively small release. Its main aim is to avoid changing too much of the core code, while addressing issues and adding new features and improvements over 2.0, in a timely fashion.

Objective

Ganeti 2.1 will add features to help further automatization of cluster operations, further improbe scalability to even bigger clusters, and make it easier to debug the Ganeti core.

Background

Overview

Detailed design

As for 2.0 we divide the 2.1 design into three areas:

• core changes, which affect the master daemon/job queue/locking or all/most logical units
• logical unit/feature changes
• external interface changes (eg. command line, os api, hooks, ...)
