Things done in PikeNeutron:

Ø “Support for zero-downtime upgrades from Ocata (a.k.a. rollingupgrades)

Ø haproxy is now used instead of the neutron namespace proxy agentfor reduced memory usage on the server running the metadata proxy

Ø Improvements to stability/performance, QoS, DVRØ Support for quota usage amounts in quota APIØ Support for individual DNS domains set per Neutron portØ Support for per-network MTU overridesØ Support for user-defined tags on all standard Neutron resources”

Things done in Pike

Cinder:

Ø Having a “revert to snapshot” featureØ Supporting extending a volume that is in-use.

Ø Added volume group replication support

Things done in Pike

Nova:

Ø Moved on to Cell v2§ Timeline: nova-network deprecated in Newton. Cellsv1 only runs undernova-network in Ocata. Cellsv2 required in Ocata. Multi-cell cellsv2 availablein Pike.

Ø Introduced Placement§ In Pike, didn’t properly handle migrations§ Got some fixes in Pike, should do better solution in Queens

Things done in Pike

Ironic:

Ø Boot from Cinder volumesØ Rolling upgrade between releasesØ Driver composition reform (dynamic driver model)Ø Redfish hardware type

§ Features implemented in a vendor-agnostic fashion

Things done in Pike

Kolla:

Ø Docker images for about 50 OpenStack servicesØ Ansible roles for about 50 OpenStack servicesØ Kolla-kubernetes nearly has compute kit

Nova:Ø Cell v2

§ Drop nova-network and Cell v1§ Efficiently listing instances in a multi-cell deployment§ Efficiently cross-cell queries

Ø Placement§ Traits: qualitative part of resources (besides the quantitative part)§ Nested resource providers

• PCI devices can have Physical Functions (PFs), each of which can supply a number ofVirtual Functions (VFs)

• May not be complete in Queens§ Generic Device Management§ Separate Placement out into its own service

Things continue Queens

Neutron:

Ø Improve Neutron documentation for simpler deploymentsØ Can delete neutron CLI at the end of R cycleØ Security group logging

Things continue in Queens

Cinder:

Ø Show resource's total count info in list APIs [1]

Ø Report backend state in service listØ Apply encryption and qos per volume
