# === Parameters:
|
|
#
|
|
# [*scheduler_host_subset_size*]
|
|
# (optional) defines the subset size that a host is chosen from
|
|
# Defaults to $::os_service_default

|
#
|
|
# [*max_io_ops_per_host*]
|
|
# (optional) Ignore hosts that have too many builds/resizes/snaps/migrations
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*max_instances_per_host*]
|
|
# (optional) Ignore hosts that have too many instances
|
|
# Defaults to $::os_service_default

|
|
# (optional) An array of images to run on isolated host
|
|
# Defaults to $::os_service_default
|
|
#

|
|
# Defaults to $::os_service_default
|
|
#

|
|
# Example: ['first.filter.class', 'second.filter.class']
|
|
# Defaults to ['nova.scheduler.filters.all_filters']

# [*shuffle_best_same_weighed_hosts*]
|
|
# (Optional) Enabled spreading the instances between hosts with the same
|
|
# best weight
