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.
