WHAT'S NEW IN VERSION 6
● OpenStack Compute (Nova)
● Guest vCPU topology configurability
● Support definition of vCPU NUMA topologies and sockets/cores/threads to expose to
guests.
● Defined in flavor extra specifications and/or image properties.
● Useful where guest operating system has specific topology requirements or to maximize
guest performance by aligning it with expected host topologies.
● Evacuation to a scheduled host.
● Evacuate previously required user specified target host.
● Target host is now optional, scheduler can instead pick best target.

● OpenStack Compute (Nova)
● Instance support for interactive serial console.
● Support for per-image config drive format.
● It is now possible to set expected configuration drive format using image properties rather
than global configuration value.
● Allows mix of vfat, iso9660, to match guest expectations.
● Compute driver for Baremetal (Ironic) – Technology Preview

OpenStack Identity (Keystone)
● LDAP Multi-backend
Keystone now supports the integration of multiple Identity Providers together in a single
Keystone Instance, Using a mapping layer to store the domain and local ID for the public facing
user and group IDs.
● Support Compression of the PKI token
PKI tokens are topping out over 8K, this adds support for optional compression to shrink the
token size.
● Endpoint Policy Assignment
OS-POLICY Provides the means to assign policy files to specific endpoint, or to all endpoints for
a specific services via the API.

OpenStack Identity (Keystone)
● Stand alone service catalog
This introduces a standalone V3 API request to fetch an authenticated service catalog, for use
with tokens that do not contain a catalog
● Enable filtering of Policy credentials by user_id
This enables filtering policy files by user_id attribute which enables users to have access only to
their credentials.

● OpenStack Object Storage (Swift)
● Storage Policies
● Storage Policies allow for some level of segmenting the cluster for various purposes
through the creation of multiple object ring.
● Once configured, users can create a container with a particular policy
● Storage Policies can be set for:
● Different Storage implementations:
● Different Diskfile (e.g. GlusterFS, Kinetic) for group of nodes
● Different levels of replication
● Different Performance profiles (e.g. SSD-only)

● OpenStack Object Storage (Swift)
●Multi-ring awareness
● Object replication - added to be aware of the different locations on-disk that storage
policies introduced
● Large objects - Refactoring work for storage polices
● Object auditing – added to be aware of the different on-disk locations for objects in
different storage policies
● Improve partition placement
● The swift-ring-builder has been updated to first prefer device weight, then use failure
domains to break ties.
* The progress on multi-ring and storage policies is the foundation to the the Swift Erasure code
development that is on-going.

● OpenStack Block Storage (Cinder)
● Pool-aware Scheduler
● Cinder was extended to be aware of storage pools within
backend and also use them as finest granularity for resource
placement.
● Volume Num Weighter
● Added the support to choose volume backend based on
volume number in volume backend, to improve volumes IO
balancing performance.

● OpenStack Block Storage (Cinder)
● Cinder volumes replication
● Enable Cinder to leverage volume replication features
available in storage backends including failover, failback as
well as reverse direction capabilities for disaster recovery.
● Consistency Groups
● Consistency groups support was added to group volumes
together for the purpose of application data protection (with
the focus of snapshots for disaster recovery)

● OpenStack Image Storage (Glance)
● Asynchronous Processing
● Added the async worker support for processing to be
performed on an image without delaying the user (such as
image imports tasks etc)
● Metadata Definitions Catalog
● A new catalog was added to define available metadata that
can be used on different types of resources (images,
artifacts, volumes, flavors etc). So, a user through Horizon,
would be able to search this catalog to list the available
properties they can add to a flavor or image. Example:
hw_cpu_cores=1 (images) hw:cpu_cores=1 (flavor)

● OpenStack Image Storage (Glance)
● Image download improvements:
● Download image restriction policy
● A support was added to restrict users from downloading
image based on policy. Until Juno release, images got to
be shared publicly with the users can download these
images freely without restriction that could have lead to
piracy.
● Restart of partial download
● Solved a problem associated with a very large images
download that may be interrupted prior to completion, due
to dropped connections

● OpenStack Orchestration (Heat)
● Support additional resource types:
● Data Processing (Sahara)
● Server (Instance) Groups
● Stack lifecycle improvements:
● Update a failed stack
● Cancel a stack update
● Stack update no longer requires resubmission of all original
parameters

OpenStack Dashboard (Horizon)
● Usage Data downloadable in CVS format
Allow the user to download daily usage data for all of the projects as a CSV file.
● Table Filtering is performed via API query attributes which filter complete tables, not only
single pages.
● Keystone:
● New Identity Dashboard: Identity panels are under their own dashboard, using RBAC to
determine the data to load in the identity dashboard
● New mechanism to easily switch between projects and regions, and domains.
● Horizon now supports Trove and Sahara dashboards as Tech Preview

● Nova:
● RBAC: Horizon now checks policy rules for all Nova instance actions on projects and
admin dashboards.
● Ability to evacuate nova-compute hosts
● Cinder:
● System info panel now includes Cinder services' status
● Users can now upload Cinder Volumes to Glance images
● Ability to manage Quality-of-Services for Cinder Volumes
● Ability to manage Extra Specs for volume types
● Resetting States of volumes and Snapshots

● Glance:
● Users can now manage key/value Metadata registry for images
● Neutron:
● Horizon now supports creating IPv6 subsets
● Ability to manage networks in the DHCP agent
● UI adjustments to support Distributed Virtual Routers
● RBAC: Policy checks for all Neutron actions on firewalls, loadbalancers,
network_topology, networks, routers and vpn panels.
● Heat:
● RBAC: New policy checks for heat actions
