Description of configuration options for compute

Configuration option = Default value	Description
[DEFAULT]
compute_available_monitors = ['nova.compute.monitors.all_monitors']	(MultiStrOpt) Monitor classes available to the compute which may be specified more than once.
compute_driver = None	(StrOpt) Driver to use for controlling virtualization. Options include: libvirt.LibvirtDriver, xenapi.XenAPIDriver, fake.FakeDriver, baremetal.BareMetalDriver, vmwareapi.VMwareESXDriver, vmwareapi.VMwareVCDriver
compute_manager = nova.compute.manager.ComputeManager	(StrOpt) Full class name for the Manager for compute
compute_monitors =	(ListOpt) A list of monitors that can be used for getting compute metrics.
compute_stats_class = nova.compute.stats.Stats	(StrOpt) Class that will manage stats for the local compute host
console_host = oslo	(StrOpt) Console proxy host to use to connect to instances on this host.
console_manager = nova.console.manager.ConsoleProxyManager	(StrOpt) Full class name for the Manager for console proxy
default_flavor = m1.small	(StrOpt) Default flavor to use for the EC2 API only. The Nova API does not support a default flavor.
default_notification_level = INFO	(StrOpt) Default notification level for outgoing notifications
default_publisher_id = None	(StrOpt) Default publisher_id for outgoing notifications
enable_instance_password = True	(BoolOpt) Enables returning of the instance password by the relevant server API calls such as create, rebuild or rescue, If the hypervisor does not support password injection then the password returned will not be correct
heal_instance_info_cache_interval = 60	(IntOpt) Number of seconds between instance info_cache self healing updates
image_cache_manager_interval = 2400	(IntOpt) Number of seconds to wait between runs of the image cache manager
image_cache_subdirectory_name = _base	(StrOpt) Where cached images are stored under $instances_path. This is NOT the full path - just a folder name. For per-compute-host cached images, set to _base_$my_ip
image_handlers = download	(ListOpt) Specifies which image handler extension names to use for handling images. The first extension in the list which can handle the image with a suitable location will be used.
instance_build_timeout = 0	(IntOpt) Amount of time in seconds an instance can be in BUILD before going into ERROR status.Set to 0 to disable.
instance_delete_interval = 300	(IntOpt) Interval in seconds for retrying failed instance file deletes
instance_usage_audit = False	(BoolOpt) Generate periodic compute.instance.exists notifications
instance_usage_audit_period = month	(StrOpt) Time period to generate instance usages for. Time period must be hour, day, month or year
instances_path = $state_path/instances	(StrOpt) Where instances are stored on disk
maximum_instance_delete_attempts = 5	(IntOpt) The number of times to attempt to reap an instance's files.
reboot_timeout = 0	(IntOpt) Automatically hard reboot an instance if it has been stuck in a rebooting state longer than N seconds. Set to 0 to disable.
reclaim_instance_interval = 0	(IntOpt) Interval in seconds for reclaiming deleted instances
resize_confirm_window = 0	(IntOpt) Automatically confirm resizes after N seconds. Set to 0 to disable.
resume_guests_state_on_host_boot = False	(BoolOpt) Whether to start guests that were running before the host rebooted
running_deleted_instance_action = reap	(StrOpt) Action to take if a running deleted instance is detected.Valid options are 'noop', 'log', 'shutdown', or 'reap'. Set to 'noop' to take no action.
running_deleted_instance_poll_interval = 1800	(IntOpt) Number of seconds to wait between runs of the cleanup task.
running_deleted_instance_timeout = 0	(IntOpt) Number of seconds after being deleted when a running instance should be considered eligible for cleanup.
shelved_offload_time = 0	(IntOpt) Time in seconds before a shelved instance is eligible for removing from a host. -1 never offload, 0 offload when shelved
shelved_poll_interval = 3600	(IntOpt) Interval in seconds for polling shelved instances to offload
sync_power_state_interval = 600	(IntOpt) Interval to sync power states between the database and the hypervisor
vif_plugging_is_fatal = True	(BoolOpt) Fail instance boot if vif plugging fails
vif_plugging_timeout = 300	(IntOpt) Number of seconds to wait for neutron vif plugging events to arrive before continuing or failing (see vif_plugging_is_fatal). If this is set to zero and vif_plugging_is_fatal is False, events should not be expected to arrive at all.
