Description of common configuration options

Configuration option = Default value	Description
[DEFAULT]
bindir = /usr/local/bin	(StrOpt) Directory where nova binaries are installed
compute_topic = compute	(StrOpt) The topic compute nodes listen on
console_topic = console	(StrOpt) The topic console proxy nodes listen on
consoleauth_topic = consoleauth	(StrOpt) The topic console auth proxy nodes listen on
executor_thread_pool_size = 64	(IntOpt) Size of executor thread pool.
host = localhost	(StrOpt) Name of this node. This can be an opaque identifier. It is not necessarily a hostname, FQDN, or IP address. However, the node name must be valid within an AMQP key, and if using ZeroMQ, a valid hostname, FQDN, or IP address
memcached_servers = None	(ListOpt) Memcached servers or None for in process cache.
my_ip = 10.0.0.1	(StrOpt) IP address of this host
notify_api_faults = False	(BoolOpt) If set, send api.fault notifications on caught exceptions in the API service.
notify_on_state_change = None	(StrOpt) If set, send compute.instance.update notifications on instance state changes. Valid values are None for no notifications, "vm_state" for notifications on VM state changes, or "vm_and_task_state" for notifications on VM and task state changes.
pybasedir = /home/sakaia/work/openstack-doc-tools/autogenerate_config_docs/sources/nova	(StrOpt) Directory where the nova python module is installed
report_interval = 10	(IntOpt) Seconds between nodes reporting state to datastore
rootwrap_config = /etc/nova/rootwrap.conf	(StrOpt) Path to the rootwrap configuration file to use for running commands as root
service_down_time = 60	(IntOpt) Maximum time since last check-in for up service
state_path = $pybasedir	(StrOpt) Top-level directory for maintaining nova's state
tempdir = None	(StrOpt) Explicitly specify the temporary working directory
use_rootwrap_daemon = False	(BoolOpt) Start and use a daemon that can run the commands that need to be run with root privileges. This option is usually enabled on nodes that run nova compute processes
[keystone_authtoken]
memcached_servers = None	(ListOpt) Optionally specify a list of memcached server(s) to use for caching. If left undefined, tokens will instead be cached in-process.
[workarounds]
destroy_after_evacuate = True	(BoolOpt) DEPRECATED: Whether to destroy instances on startup when we suspect they have previously been evacuated. This can result in data loss if undesired. See https://launchpad.net/bugs/1419785
disable_libvirt_livesnapshot = True	(BoolOpt) When using libvirt 1.2.2 live snapshots fail intermittently under load. This config option provides a mechanism to enable live snapshot while this is resolved. See https://bugs.launchpad.net/nova/+bug/1334398
disable_rootwrap = False	(BoolOpt) This option allows a fallback to sudo for performance reasons. For example see https://bugs.launchpad.net/nova/+bug/1415106
handle_virt_lifecycle_events = True	(BoolOpt) Whether or not to handle events raised from the compute driver's 'emit_event' method. These are lifecycle events raised from compute drivers that implement the method. An example of a lifecycle event is an instance starting or stopping. If the instance is going through task state changes due to an API operation, like resize, the events are ignored. However, this is an advanced feature which allows the hypervisor to signal to the compute service that an unexpected state change has occurred in an instance and the instance can be shutdown automatically - which can inherently race in reboot operations or when the compute service or host is rebooted, either planned or due to an unexpected outage. Care should be taken when using this and sync_power_state_interval is negative since then if any instances are out of sync between the hypervisor and the Nova database they will have to be synchronized manually.
