Description of configuration options for cells

Configuration option = Default value	Description
[cells]
call_timeout = 60	(IntOpt) Seconds to wait for response from a call to a cell.
capabilities = hypervisor=xenserver;kvm, os=linux;windows	(ListOpt) Key/Multi-value list with the capabilities of the cell
cell_type = compute	(StrOpt) Type of cell: api or compute
cells_config = None	(StrOpt) Configuration file from which to read cells configuration. If given, overrides reading cells from the database.
driver = nova.cells.rpc_driver.CellsRPCDriver	(StrOpt) Cells communication driver to use
enable = False	(BoolOpt) Enable cell functionality
instance_update_num_instances = 1	(IntOpt) Number of instances to update per periodic task run
instance_updated_at_threshold = 3600	(IntOpt) Number of seconds after an instance was updated or deleted to continue to update cells
manager = nova.cells.manager.CellsManager	(StrOpt) Manager for cells
max_hop_count = 10	(IntOpt) Maximum number of hops for cells routing.
mute_child_interval = 300	(IntOpt) Number of seconds after which a lack of capability and capacity updates signals the child cell is to be treated as a mute.
mute_weight_multiplier = -10.0	(FloatOpt) Multiplier used to weigh mute children. (The value should be negative.)

name = nova	(StrOpt) name of this cell
offset_weight_multiplier = 1.0	(FloatOpt) Multiplier used to weigh offset weigher.
reserve_percent = 10.0	(FloatOpt) Percentage of cell capacity to hold in reserve. Affects both memory and disk utilization
topic = cells	(StrOpt) the topic cells nodes listen on
