placement 12.0.2 (dalmatian)

We are pumped to announce the release of: placement 12.0.2 This release is part of the dalmatian release series. The source is available from: https://opendev.org/openstack/placement Download the package from: https://pypi.org/project/placement Please report issues through: https://storyboard.openstack.org/#!/project/openstack/placement For more details, please see below. 12.0.2 ^^^^^^ Bug Fixes * Added a new config option "[workarounds]optimize_for_wide_provider_trees". It is disable by default. As reported in bug #2126751 in the situation where many similar child provider is defined under the same root provider, placement's allocation candidate generation algorithm scales poorly. This config option enables certain optimizations that help decrease the time it takes to generate the GET /allocation_candidates response for queries requesting multiple resources from those child providers. It should be enabled if you have at least 8 child resource providers within a tree providing inventory of the same resource class. And you are trying to support VMs with more than 4 such resources. E.g.: * Nova's PCI in Placement feature is enabled and you have at least 8 PCI devices with the same product_id in a single compute and you are using flavors requesting more than 4 such devices. * Nova's GPU support is enabled and you have at least 8 GPUs per compute node while requesting more than 4 per VM. You can keep it disabled if you have a flat resource provider tree, i.e. all resources reported on the root provider. Or if your flavors are not requesting more than 4 PCI or GPU resources of the same type.

os-vif 4.3.0 (gazpacho)
by no-reply＠openstack.org 02 Feb '26

02 Feb '26

We are delighted to announce the release of: os-vif 4.3.0 This release is part of the gazpacho release series. The source is available from: https://opendev.org/openstack/os-vif Download the package from: https://pypi.org/project/os-vif Please report issues through: https://bugs.launchpad.net/os-vif/+bugs For more details, please see below. 4.3.0 ^^^^^ New Features * Added support for os-vif to pre-create TAP devices when using OVS/OVN. The "VIFPortProfileOpenVSwitch" object now supports two new fields: * "create_tap": When set to "True", os-vif will create the TAP device with the correct MAC address and MTU before adding it to OVS. * "multiqueue": When set to "True" along with "create_tap", the TAP device will be created with multiqueue support enabled for improved performance with multiple vCPUs. The multiqueue setting is determined by Nova from the "hw:vif_multiqueue_enabled" flavor extra spec or image property. When the "[ovn]/ovs_create_tap" config option is enabled in Neutron's ML2/OVN mechanism driver, Neutron sets the "ovs_create_tap" flag in the vif_details during port binding. Nova then reads this value and propagates it to os-vif via the "create_tap" field, and configures libvirt with "managed="no"" so it uses the pre-created TAP device. This reduces live migration downtime by ensuring the network is fully wired before the VM starts. See bug 2069718 (https://bugs.launchpad.net/neutron/+bug/2069718) Changes in os-vif 4.2.1..4.3.0 ------------------------------ eba8007 Add TAP device pre-creation support for OVS/OVN 1c0a741 Fixed bridge name when per_port_bridge is used b4f277f Stabilize functional test 8427453 reno: Update master for unmaintained/2024.1 05bb255 Update master for stable/2025.2 134622b Remove remaining job with Ubuntu Jammy (22.04) Diffstat (except docs and test files) ------------------------------------- .zuul.yaml | 11 - os_vif/internal/ip/ip_command.py | 8 +- os_vif/internal/ip/linux/impl_pyroute2.py | 11 +- os_vif/objects/vif.py | 30 ++- .../internal/command/ip/test_impl_pyroute2.py | 111 +++++++++ .../unit/internal/ip/linux/test_impl_pyroute2.py | 66 +++++ .../add-tap-creation-support-2069718-abc123.yaml | 24 ++ releasenotes/source/2024.1.rst | 2 +- releasenotes/source/2025.2.rst | 6 + releasenotes/source/index.rst | 1 + vif_plug_ovs/exception.py | 6 + vif_plug_ovs/linux_net.py | 23 ++ vif_plug_ovs/ovs.py | 59 ++++- 18 files changed, 765 insertions(+), 30 deletions(-)

Secret-caching typically reduces the load on Keystone and is required for Keystone users to be able to use signed aws-chunked transfers.
