prelude: |
|
|
The 17.0.0 release includes many new features and bug fixes. It is
|
|
difficult to cover all the changes that have been introduced. Please at
|
|
least read the upgrade section which describes the required actions to
|
|
upgrade your cloud from 16.0.0 (Pike) to 17.0.0 (Queens).
|
|
|
|
That said, a few major changes are worth mentioning. This is not an
|
|
exhaustive list:
|
|
|
|
- The latest Compute API microversion supported for Queens is v2.60. Details
|
|
on REST API microversions added since the 16.0.0 Pike release can be
|
|
found in the `REST API Version History`_ page.
|
|
- The placement service should be upgraded before the nova controller and
|
|
compute services. See the `Pike Upgrade Notes for Queens`_ for more
|
|
details.
|
|
- Some of the `multi-cell cells v2 caveats`_ have been resolved.
|
|
- Cells v1 and nova-network continue to be deprecated, and plan to be
|
|
removed in the 18.0.0 Rocky release.
|
|
- The libvirt and xenapi compute drivers now have (experimental) native
|
|
support for virtual GPU devices. See the `virtual GPU`_ admin guide for
|
|
more details.
|
|
- The libvirt compute driver now supports volume multi-attach when using
|
|
the 2.60 compute API microversion. See the cinder admin guide for more
|
|
details about volume multi-attach support in OpenStack.
|
|
- Version 1.0.0 of the `osc-placement plugin`_ has been released which
|
|
provides CLI support for interacting directly with the Placement API.
|
|
- Traits-based scheduling is now available for the ironic compute driver.
|
|
For more details, see the `ironic docs for scheduling based on traits`_.
