(optional) The path at the end of the uri for communication with the VNC proxy server Defaults to ‘/vnc_auto.html’
- force_config_drive
-
(optional) Whether to force the config drive to be attached to all VMs Defaults to $facts
- instance_usage_audit
-
(optional) Generate periodic compute.instance.exists notifications. Defaults to $facts
- instance_usage_audit_period
-
(optional) Time period to generate instance usages for. Time period must be hour, day, month or year with/without offset. Defaults to $facts
- flat_injected
-
(optional) This option determines whether the network setup information is injected into the VM before it is booted. Defaults to $facts
- mkisofs_cmd
-
(optional) Name or path of the tool used for ISO image creation. Defaults to $facts
- use_cow_images
-
(optional) Enable use of copy-on-write (cow) images. Defaults to $facts
- force_raw_images
-
(optional) Force backing images to raw format. Defaults to $facts
- virt_mkfs
-
(optional) Name of the mkfs commands for ephemeral device. The format is <os_type>=<mkfs command> Defaults to $facts
- reserved_host_cpus
-
(optional) Number of host CPUs reserved for the host. Defaults to $facts
- reserved_host_memory
-
(optional) The amount of memory in MB reserved for the host. Defaults to $facts
- reserved_host_disk
-
(optional) The amount of disk in MB reserved for the host. Defaults to $facts
- update_resources_interval
-
(optional) Interval for updating compute resources. This option specifies how often the update_available_resources periodic task should run. A number less than 0 means to disable the task completely Leaving this at the default of 0 will cause this to run at the default periodic interval. Setting it to any positive value will cause it to run at approximately that number of seconds. Defaults to $facts
- reboot_timeout
-
(optional) Time interval after which an instance is hard rebooted automatically. Setting this option to a time period in seconds will automatically hard reboot an instance if it has been stuck in a rebooting state longer than N seconds. Defaults to $facts
- instance_build_timeout
-
(optional) Maximum time in seconds that an instance can take to build. If this timer expires, instance status will be changed to ERROR. Enabling this option will make sure an instance will not be stuck in BUILD state for a longer period. Defaults to $facts
- rescue_timeout
-
(optional) Interval to wait before un-rescuing an instance stuck in RESCUE. Defaults to $facts
- resize_confirm_window
-
(optional) Automatically confirm resizes after N seconds. Resize functionality will save the existing server before resizing. After the resize completes, user is requested to confirm the resize. The user has the opportunity to either confirm or revert all changes. Confirm resize removes the original server and changes server status from resized to active. Setting this option to a time period (in seconds) will automatically confirm the resize if the server is in resized state longer than that time. Defaults to $facts
- shutdown_timeout
-
(optional) Total time to wait in seconds for an instance to perform a clean shutdown. It determines the overall period (in seconds) a VM is allowed to perform a clean shutdown. While performing stop, rescue and shelve, rebuild operations, configuring this option gives the VM a chance to perform a controlled shutdown before the instance is powered off. Defaults to $facts
- cpu_shared_set
-
(optional) Mask of host CPUs that can be used for “VCPU“ resources and offloaded emulator threads. Defaults to $facts
- cpu_dedicated_set
-
(optional) A list or range of host CPU cores to which processes for pinned instance CPUs (PCPUs) can be scheduled. Defaults to $facts
- resume_guests_state_on_host_boot
-
(optional) This option specifies whether to start guests that were running before the host rebooted. It ensures that all of the instances on a Nova compute node resume their state each time the compute node boots or restarts. Defaults to $facts
- max_concurrent_builds
-
(optional) Maximum number of instance builds to run concurrently Defaults to $facts
- max_concurrent_live_migrations
-
(optional) Maximum number of live migrations to run in parallel. Defaults to $facts
- sync_power_state_pool_size
-
(optional) Maximum number of greenthreads to use when syncing power states. Defaults to $facts
- sync_power_state_interval
-
(optional) Interval to sync power states between the database and the hypervisor. Set to -1 to disable. Setting this to 0 will run at the default rate. Defaults to $facts

-
(optional) Map of physnet name as key and list of NUMA nodes as value. Defaults to {}
- neutron_tunnel_numa_nodes
-
(optional) List of NUMA nodes to configure NUMA affinity for all tunneled networks. Defaults to []

-
(optional) whether to wait for “network-vif-plugged“ events before starting guest transfer Defaults to $facts
- max_disk_devices_to_attach
-
(optional) specifies max number of devices that can be attached to a single server. Note that the number of disks supported by an server depends on the bus used. For example, the ide disk bus is limited to 4 attached devices. The configured maximum is enforced during server create, rebuild, evacuate, unshelve, live migrate, and attach volume. Defaults to $facts
- default_access_ip_network_name
-
(optional) Name of the network to be used to set access IPs for instances. If there are multiple IPs to choose from, an arbitrary one will be chosen. Defaults to $facts

-
(optional) Time interval in seconds to wait between runs for the clean up action. If set to 0, deleted instances check will be disabled. Defaults to $facts
