17.2.0
^^^^^^


Known Issues
************

* When using the minimim-bandwidth QoS feature due to bug
  https://launchpad.net/bugs/1921150 physical NIC resource providers
  were for some time created with the wrong parent (i.e. the
  hypervisor RP). This is now partially fixed and new resource
  providers are created now with the expected parent (i.e. the agent
  RP).  However Placement does not allow re-parenting an already
  existing resource provider, therefore the following Placement DB
  update may be needed after the fix for bug 1921150 is applied:
  neutron/tools/bug-1921150-re-parent-device-rps.sql Until all
  resource providers have the proper parent, neutron-server will retry
  the re-parenting update, which will be rejected every time,
  therefore expect polluted logs and some wasted load on Placement.
  However please note that the bandwidth-aware scheduling is supposed
  to work even with the wrongly parented resource providers.


Bug Fixes
*********

* 1926693 (https://bugs.launchpad.net/neutron/+bug/1926693) The
  logic to detect the hypervisor hostname, which was introduced by
  change 69660
  (https://review.opendev.org/c/openstack/neutron/+/696600), has been
  fixed and now returns the result consistent with libvirt.

* The new "resource_provider_defualt_hypervisor" option has been
  added, to replace the default hypervisor name to locates the root
  resource provider without giving a complete list of interfaces or
  bridges in the "resource_provider_hypervisors" option. This option
  is located in the "[ovs]" ini-section for "ovs-agent" and
  "[sriov_nic]" ini-section for "sriov-agent".
