The OpenStack 2024.2 (Nova 30.0.0) 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 29.0.0 (2024.1) to 30.0.0
|
|
(2024.2).
|
|
As a reminder, OpenStack 2024.2 is not a `Skip-Level-Upgrade Release`__
|
|
(starting from now, we name it a `SLURP release`) meaning that you can't
|
|
do rolling-upgrade from 2023.2, you first need to upgrade to 2024.1.

|
There are a few major changes worth mentioning. This is not an exhaustive
|
|
list:
|
|
|
|
- The latest Compute API microversion supported for 2024.2 is `v2.96`__.

|
|

|
|
|
|
- With the libvirt driver and libvirt version 7.3.0 or newer, mediated
|
|
devices for vGPUs are now persisted across reboots of a compute host.
|
|
|
|
- Instances with UEFI firmware can now be launched with stateless firmware
|
|
if their image has the ``hw_firmware_stateless`` property and if the
|
|
compute services have libvirt 8.6.0 or later.
|
|
|
|
- Nova now automatically detects vTPM support for compute services if
|
|
libvirt version is above 8.0.0 and if ``swtpm`` is installed on the node.
|
|
It will also automatically get the TPM models that are supported.
|
|
|
|
- You can now require TLS connections for SPICE consoles if you set the
|
|
``[spice]/require_secure`` configuration option to ``True``.
|
|
|
|
- ``AggregateMultitenancyIsolation`` scheduler filter now supports multiple
|
|
aggregate keys prefixed by ``filter_tenant_id`` which removes the
|
|
limitation on the number of tenants an aggregate of hosts can relate to.
|
|
|
|
- A couple of other improvements target reducing the number of bugs we
|
|
have: one is changing how the Ironic driver sends metadata to the Ironic
|
|
API, and another one created a new ``nova.wsgi`` WSGI module that allows
|
|
different WSGI servers to set their WSGI application the same way (using
|
|
module instead of a binary).
