# == Class: nova::scheduler::filter
#
# This class is aim to configure nova.scheduler filter
#
# === Parameters:
#
# [*host_subset_size*]
# (optional) defines the subset size that a host is chosen from
# Defaults to $facts['os_service_default']
#
# [*max_io_ops_per_host*]
# (optional) Ignore hosts that have too many builds/resizes/snaps/migrations
# Defaults to $facts['os_service_default']
#
# [*max_instances_per_host*]
# (optional) Ignore hosts that have too many instances
# Defaults to $facts['os_service_default']
#
# [*isolated_images*]
# (optional) An array of images to run on isolated host
# Defaults to $facts['os_service_default']
#
# [*isolated_hosts*]
# (optional) An array of hosts reserved for specific images
# Defaults to $facts['os_service_default']
#
# [*available_filters*]
# (optional) An array with filter classes available to the scheduler.
# Example: ['first.filter.class', 'second.filter.class']
# Defaults to ['nova.scheduler.filters.all_filters']
#
# [*enabled_filters*]
# (optional) An array of filters to be used by default
# Defaults to $facts['os_service_default']
#
# [*weight_classes*]
# (optional) Which weight class names to use for weighing hosts
# Defaults to 'nova.scheduler.weights.all_weighers'
#
# [*track_instance_changes*]
# (optional) Enable querying of individual hosts for instance information.
# Defaults to $facts['os_service_default']
#
# [*ram_weight_multiplier*]
# (optional) Ram weight multiplier ratio. This option determines how hosts
# with more or less available RAM are weighed.
# Defaults to $facts['os_service_default']
#
# [*cpu_weight_multiplier*]
# (optional) CPU weight multiplier ratio. This options determines how hosts
# with more or less available CPU cores are weighed. Negative numbers mean
# to stack vs spread.
# Defaults to $facts['os_service_default']

# [*disk_weight_multiplier*]
# (optional) Disk weight multiplier ratio. Multiplier used for weighing free
# disk space. Negative numbers mean to stack vs spread.
# Defaults to $facts['os_service_default']
#
# [*io_ops_weight_multiplier*]
# (optional) IO operations weight multiplier ratio. This option determines
# how hosts with differing workloads are weighed
# Defaults to $facts['os_service_default']
#
# [*soft_affinity_weight_multiplier*]
# (optional) Multiplier used for weighing hosts for group soft-affinity
# Defaults to $facts['os_service_default']
#
# [*soft_anti_affinity_weight_multiplier*]
# (optional) Multiplier used for weighing hosts for group soft-anti-affinity
# Defaults to $facts['os_service_default']
#
# [*build_failure_weight_multiplier*]
# (optional) Multiplier used for weighing hosts that have had recent build
# failures
# Defaults to $facts['os_service_default']
#
# [*cross_cell_move_weight_multiplier*]
# (optional) Multiplier used for weighing hosts during a cross-cell move
# Defaults to $facts['os_service_default']
#
# [*num_instances_weight_multiplier*]
# (optional) Number of instances weight multiplier ratio.
# Defaults to $facts['os_service_default']
#
# [*hypervisor_version_weight_multiplier*]
# (optional) Hypervisor Version weight multiplier ratio.
# Defaults to $facts['os_service_default']
#
# [*shuffle_best_same_weighed_hosts*]
# (optional) Enabled spreading the instances between hosts with the same
# best weight
# Defaults to $facts['os_service_default']
#
# [*restrict_isolated_hosts_to_isolated_images*]
# (optional) Prevent non-isolated images from being built on isolated hosts.
# Defaults to $facts['os_service_default']
#
# [*aggregate_image_properties_isolation_namespace*]
# (optional) Image property namespace for use in the host aggregate
# Defaults to $facts['os_service_default']
#
# [*aggregate_image_properties_isolation_separator*]
# (optional) Separator character(s) for image property namespace and name
# Defaults to $facts['os_service_default']
#
# [*pci_in_placement*]
# (optional) Enable scheduling and claiming PCI devices in Placement.
# Defaults to $facts['os_service_default']
