Architectural evolution on the scheduler has continued, along with key bug fixes: * Adds object model for a launch request spec (partially complete) (https://blueprints.launchpad.net/nova/+spec/request-spec-object) * Move resource allocation ratios from scheduler to resource tracker (https://blueprints.launchpad.net/nova/+spec/allocation-ratio-to-resource-tracker) * Fix resource tracking for operations that move instances between hosts (https://blueprints.launchpad.net/nova/+spec/migration-fix-resource-tracking) * Improved user feedback when returning ''NoValidHost'' from the scheduler (http://specs.openstack.org/openstack/nova-specs/specs/liberty/approved/add_exceeded_max_retries_exception.html).
scheduler の構造革新は継続中で、これに伴い重要なバグ修正が行われました。
