33.0.0.0rc1-16¶

The default concurrency mode is now switched from eventlet to native threading for nova-conductor, and nova-compute services. The concurrency mode can still be switched back to eventlet if needed per service. Please read the concurrency guide for more details.

When you are upgrading to 2026.2 (Hibiscus) or newer the default configuration of nova-conductor, and nova-compute services change to run these services with native threading mode by default instead of the legacy eventlet mode. We recommend to decouple the upgrade from the concurrency mode change to reduce the risk of issues. To do that either test the native threading mode of these services already in 2026.1 (Gazpacho) or ensure that your service configuration is explicitly using the eventlet mode before you upgrade and only change to threading mode after the upgrade was successful. Please read the concurrency guide for more details on how to configure the mode.

Bug #2144660: Fix NUMA cell sorting for non-PCI VMs with pack strategy. When using the pack NUMA cell allocation strategy, the compute claim was not passing pci_stats to numa_fit_instance_to_host for VMs without PCI requests. This caused the PCI-aware NUMA cell sort to be skipped, allowing non-PCI VMs to land on NUMA nodes holding PCI devices instead of being steered away from them.
