We are excited to announce the release of: nova 30.2.0 This release is part of the dalmatian release series. The source is available from: https://opendev.org/openstack/nova Download the package from: https://tarballs.openstack.org/nova/ Please report issues through: https://bugs.launchpad.net/nova/+bugs For more details, please see below. 30.2.0 ^^^^^^ Bug Fixes * Fixed the issue bug 2098496 where nova assigned more PCI hostdevs to a VM than the flavor requested via the pci_passthrough:alias extra_spec. This only affected systems where both "[filter_scheduler]pci_in_placement" and "[pci]report_in_placement" were set to True. This only affected systems where the PCI alias requested type-VF devices and a single PF device on the compute node supported more than one VFs and "[pci]device_spec" configuration allowed nova to use multiple VFs from a single PF. * [bug 2117170 (https://bugs.launchpad.net/nova/+bug/2117170)] Libvirt driver no longer enables VMCoreInfo device when an instance has memory encryption is enabled, to avoid kernel crash caused by fw_cfg device in guest requiring DMA. * Fixed performance issue with the "/os-hypervisors/detail" API endpoint when using microversion 2.88 or higher. The API was making sequential RPC calls to each compute node to gather uptime information, causing significant delays in environments with many compute nodes (LP#2122036). The fix optimizes uptime retrieval by: * Adding uptime information to the periodic resource updates sent by nova-compute to the database, eliminating the need for synchronous RPC calls during API requests * Only attempting RPC-based uptime retrieval for hypervisor types that actually support it (libvirt and z/VM), avoiding unnecessary calls to other hypervisor types that would always return NotImplementedError * Preferring cached uptime data from the database over RPC calls when available, this updates at the cadence specified by *[DEFAULT]update_resources_interval* which is the same interval the other hypervisor stats update. This change significantly reduces response times for the hypervisor detail API in large deployments while maintaining backward compatibility. * The nova (metadata)api wsgi application will now detect fatal errors (configuration, et al) on startup and lock into a permanent error state until fixed and restarted. This solves a problem with some wsgi runtimes ignoring initialization errors and continuing to send requests to the half-initialized service. See https://bugs.launchpad.net/nova/+bug/2103811 for more details.
