We are delighted to announce the release of: nova 16.0.0: Cloud computing fabric controller This release is part of the pike release series. Download the package from: https://tarballs.openstack.org/nova/ For more details, please see below. 16.0.0 ^^^^^^ Known Issues ************ * Due to the changes in scheduling of bare metal nodes, additional resources may be reported as free to Placement. This happens in two cases: * An instance is deployed with a flavor smaller than a node (only possible when exact filters are not used) * Node properties were modified in ironic for a deployed nodes When such instances were deployed without using a custom resource class, it is possible for the scheduler to try deploying another instance on the same node. It will cause a failure in the compute and a scheduling retry. The recommended work around is to assign a resource class to all ironic nodes, and use it for scheduling of bare metal instances. Deprecation Notes ***************** * The configuration options "baremetal_enabled_filters" and "use_baremetal_filters" are deprecated in Pike and should only be used if your deployment still contains nodes that have not had their resource_class attribute set. See Ironic release notes (https://docs.openstack.org/releasenotes/ironic/) for upgrade concerns. * The following scheduler filters are deprecated in Pike: "ExactRamFilter", "ExactCoreFilter" and "ExactDiskFilter" and should only be used if your deployment still contains nodes that have not had their resource_class attribute set. See Ironic release notes (https://docs.openstack.org/releasenotes/ironic/) for upgrade concerns. * Scheduling bare metal (ironic) instances using standard resource classes (VCPU, memory, disk) is deprecated and will no longer be supported in Queens. Custom resource classes should be used instead. Please refer to the ironic documentation (https://docs.openstack.org/ironic/latest/install/configure-nova- flavors.html#scheduling-based-on-resource-classes) for a detailed explanation. Bug Fixes ********* * The ironic virt driver no longer reports an empty inventory for bare metal nodes that have instances on them. Instead the custom resource class, VCPU, memory and disk are reported as they are configured on the node.
