prelude: |
|
|
The 24.0.0 release includes many new features and bug fixes. Please be
|
|
sure to read the upgrade section which describes the required actions to
|
|
upgrade your cloud from 23.0.0 (Wallaby) to 24.0.0 (Xena).
|
|
|
|
There are a few major changes worth mentioning. This is not an exhaustive
|
|
list:
|
|
|
|
- The latest Compute API microversion supported for Xena is v2.90.
|
|
Details on REST API microversions added since the 23.0.0 Wallaby release
|
|
can be found in the `REST API Version History`__ page.

|
|
|
|
- `Support for accelerators`__ in Nova servers has been improved. Now
|
|
Cyborg-managed SmartNICs can be attached as SR-IOV devices.
|
|
|
|
.. __: https://docs.openstack.org/api-guide/compute/accelerator-support.html
|
|
|
|
|
|
- Two new ``nova-manage`` CLI commands can be used for `checking`__ the
|
|
volume attachment connection information and for `refreshing`__ it if the
|
|
connection is stale (for example with a Ceph backing store and MON IP
|
|
addresses). Some documentation on how to use them can be found `here`__.

|

|
|
|
|
- Instance hostnames published by the metadata API service or config drives
|
|
can be explicitly defined at instance creation time thanks to the new
|
|
`2.90 API microversion`__. See the ``hostname`` field documentation on
|
|
the `API docs`__ for further details.

|
|
|
|
- Libvirt virt driver now supports any PCI device, not just virtual
|
|
GPUs, that are using the ``VFIO-mdev`` virtualization framework, like
|
|
network adapters or compute accelerators. `See more in the spec`__.
