14.0.4
^^^^^^


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

* When generating Libvirt XML to attach network interfaces for the
  *tap*, *ivs*, *iovisor*, *midonet*, and *vrouter* virtual interface
  types Nova previously generated an empty path attribute to the
  script element (*<script path=''/>*) of the interface.

  As of Libvirt 1.3.3 (commit) and later Libvirt no longer accepts an
  empty path attribute to the script element of the interface. Notably
  this includes Libvirt 2.0.0 as provided with RHEL 7.3 and CentOS
  7.3-1611. The creation of virtual machines with offending interface
  definitions on a host with Libvirt 1.3.3 or later will result in an
  error "libvirtError: Cannot find '' in path: No such file or
  directory".

  Additionally, where virtual machines already exist that were created
  using earlier versions of Libvirt interactions with these virtual
  machines via Nova or other utilities (e.g. *virsh*) may result in
  similar errors.

  To mitigate this issue Nova no longer generates an empty path
  attribute to the script element when defining an interface. This
  resolves the issue with regards to virtual machine creation. To
  resolve the issue with regards to existing virtual machines a change
  to Libvirt is required, this is being tracked in Bugzilla 1412834

Bug Fixes
*********

* Fixes bug 1662699 which was a regression in the v2.1 API from the
  "block_device_mapping_v2.boot_index" validation that was performed
  in the legacy v2 API. With this fix, requests to create a server
  with "boot_index=None" will be treated as if "boot_index" was not
  specified, which defaults to meaning a non-bootable block device.
