A new image metadata prefilter has been added to allow translation of
hypervisor-specific device model requests to standard traits. When this
feature is enabled, nova is able to utilize placement to select hosts that
are capable of emulating the requested devices, avoiding hosts that
could not support the request. This feature is currently supported by the
libvirt driver and can be enabled by configuring the
``[scheduler]/image_metadata_prefilter`` to ``True`` in the controller
``nova.conf``.
