-# The nova::cells class installs the Nova Cells
-#
-# == Parameters
-# [*enabled*]

-# [*instance_updated_at_threshold*]
-# Number of seconds after an instance was updated or deleted to continue to update cells
-# Defaults to '3600'
-#
-# [*max_hop_count*]

-#
-# [*cell_name*]
-# name of this cell
-# Defaults to 'nova'
-#
-# [*cell_parent_name*]
-# * If a child cell, this is the name of the 'parent' cell.
-# * If a parent cell, should be left to undef.
-#
-# [*capabilities*]
-# Key/Multi-value list with the capabilities of the cell
-# Defaults to 'hypervisor=xenserver;kvm,os=linux;windows'
-#
-# [*call_timeout*]
-# Seconds to wait for response from a call to a cell

-# Percentage of cell capacity to hold in reserve. Affects both memory and disk utilization
-# Defaults to '10.0'
-#
-# [*cell_type*]
-# Type of cell: parent or child
-# Defaults to 'None'
-#
-# [*mute_child_interval*]
-# Number of seconds after which a lack of capability and
-# capacity updates signals the child cell is to be treated as a mute
-# Defaults to '300'
-#
-# [*bandwidth_update_interval*]
-# Seconds between bandwidth updates for cells
-# Defaults to '600'

-#
-# [*scheduler_retry_delay*]
-# How often to retry in seconds when no cells are available
-# Defaults to '2'
-#
-# [*db_check_interval*]
-# Seconds between getting fresh cell info from db
-# Defaults to '60'
-#
-# [*mute_weight_multiplier*]
-# Multiplier used to weigh mute children (The value should be negative)
-# Defaults to '-10.0'
-#
-# [*mute_weight_value*]
-# Weight value assigned to mute children (The value should be positive)
-# Defaults to '1000.0'
-#
-# [*ram_weight_multiplier*]
-# Multiplier used for weighing ram. Negative numbers mean to stack vs spread
-# Defaults to '10.0'
-#
-# [*weight_offset*]
-# It might be used by some cell scheduling code in the future
-# Defaults to '1.0'
-#
-# [*weight_scale*]
-# It might be used by some cell scheduling code in the future
-# Defaults to '1.0'
