DESCRIPTION
We welcome the newest version of OpenStack - Icehouse - and set an #OSATH user group meeting to talk more on this. What's new in OpenStack In this session we are going to review all OpenStack features and emphasize on the recent developments added during the last development cycle. Following the 6-months release cycle, OpenStack releases the Icehouse version, which brings many new features and bug fixes. Some of the issues to discuss are: • compute hosts upgrade is better managed • network configuration enhancements • storage configuration and management changes • Database as a Service (Trove) integration Finally, we shall discuss what is being expected in the next development cycle, Juno.

Release highlights• Rolling upgrades on Compute nodes
– workloads remain unaffected
• Better integration of services across the platform• Increased QA through testing on drivers
– specifically storage platforms
• Improved Object Storage– /info allows service discovery && s-sync for better performance
• QoS features in Block Storage– manage heterogeneous environments
• Federated authentication– access private and public OpenStack clouds using same credentials
• Integrated Database Service– RDBMS service
Upgrade (1/3)• Swift
– no downtime
• Nova– live upgrades (limited)– first upgrade Neutron, then Nova
• Glance– oslo.messaging instead of private notifier code
• Horizon– only default domain can be managed
• Keystone– mutable_domain_id is false, may break Havana API features– oslo.messaging result to new configuration options
Upgrade (2/3)• Neutron
– ML2 plugin migration script (OVS and Linux bridge deprecated)– DB schema migration on a copy– XML is retired from the API
• Cinder– glance v2 API is not supported– nova should use v1 API– cinder.scheduler.filter_scheduler.FilterScheduler
• Ceilometer– restart agents– MongoDB 2.4 (Havana was on 2.2)
• Heat– recommended to use trusts instead of passwords– limited domain support
Upgrade (3/3)
Live upgrades as per Release Notes• upgrade controller infrastructure
– everything except nova-compute
• Havana compatibility option– [upgrade_levels]/compute=icehouse-compat
• upgrade individual compute nodes • unset compatibility option to retain the default • restart the controller services
