Bug Fixes
*********

* Fixed when placement returns ironic nodes that have just started
  automatic cleaning as possible valid candidates. This is done by
  marking all ironic nodes with an instance on them as reserved, such
  that nova only makes them available once we have double checked
  Ironic reports the node as available. If you don't have automatic
  cleaning on, this might mean it takes longer than normal for Ironic
  nodes to become available for new instances. If you want the old
  behaviour use the following workaround config:
  *[workarounds]skip_reserve_in_use_ironic_nodes=true*

* apache mod_wsgi does not support passing commandline arguments to
  the wsgi application that it hosts. As a result when the nova api or
  metadata api where run under mod_wsgi it was not posible to use
  multiple config files or non-default file names i.e. nova-api.conf
  This has been adressed by the intoduction of a new, optional,
  envionment varible "OS_NOVA_CONFIG_FILES". "OS_NOVA_CONFIG_FILES" is
  a ";" seperated list fo file path relitive to "OS_NOVA_CONFIG_DIR".
  When unset the default "api-paste.ini" and "nova.conf" will be used
  form "/etc/nova". This is supported for the nova api and nova
  metadata wsgi applications.


Other Notes
***********

* A workaround has been added to the libvirt driver to catch and
  pass migrations that were previously failing with the error:

  "libvirt.libvirtError: internal error: migration was active, but no
  RAM info was set"

  See bug 1982284 for more details.
