+If you have a custom filter, that needs to be included in the scheduler, then you can include it like so:
+
+.. code-block:: yaml
+
+ nova:
+ controller:
+ scheduler_custom_filters:
+ - my_custom_driver.nova.scheduler.filters.my_custom_filter.MyCustomFilter
+
+ # Then add your custom filter on the end (make sure to include all other ones that you need as well)
+ scheduler_default_filters: "DifferentHostFilter,RetryFilter,AvailabilityZoneFilter,RamFilter,CoreFilter,DiskFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,PciPassthroughFilter,MyCustomFilter"
