- Defined in:
- manifests/compute.pp
Overview
Class: nova::compute
Installs the nova-compute service
Parameters:
- enabled
-
(optional) Whether to enable the nova-compute service Defaults to true
- heal_instance_info_cache_interval
-
(optional) Controls how often the instance info should be updated. Defaults to ‘60’ , to disable you can set the value to zero.
- manage_service
-
(optional) Whether to start/stop the service Defaults to true
- ensure_package
-
(optional) The state for the nova-compute package Defaults to ‘present’
- vnc_enabled
-
(optional) Whether to use a VNC proxy Defaults to true

-
(optional) Whether to use a SPICE html5 proxy Mutually exclusive with vnc_enabled. Defaults to false.
- vncserver_proxyclient_address
-
(optional) The IP address of the server running the VNC proxy client Defaults to ‘127.0.0.1’
- vncproxy_host
-
(optional) The host of the VNC proxy server Defaults to false
- vncproxy_protocol
-
(optional) The protocol to communicate with the VNC proxy server Defaults to ‘http’
- vncproxy_port
-
(optional) The port to communicate with the VNC proxy server Defaults to ‘6080’
- vncproxy_path
-
(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 false
- virtio_nic
-
(optional) Whether to use virtio for the nic driver of VMs Defaults to false
- instance_usage_audit
-
(optional) Generate periodic compute.instance.exists notifications. Defaults to false
- instance_usage_audit_period
-
(optional) Time period to generate instance usages for. Time period must be hour, day, month or year Defaults to ‘month’
- force_raw_images
-
(optional) Force backing images to raw format. Defaults to true
- reserved_host_memory
-
Reserved host memory The amount of memory in MB reserved for the host. Defaults to ‘512’
- config_drive_format
-
(optional) Config drive format. One of iso9660 (default) or vfat Defaults to undef
- allow_resize_to_same_host
-
(optional) Allow destination machine to match source for resize. Useful when testing in single-host environments. Note that this can also be set in the api.pp class. Defaults to false
- 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 $::os_service_default
- cpu_shared_set
-
(optional) A list or range of host CPU cores to which emulator threads can be scheduled, if vcpu_pin_set is set, or to which both emulator threads and processes for unpinned instance CPUs (VCPUs) can be scheduled, if vcpu_pin_set is unset. Defaults to $::os_service_default
- 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 $::os_service_default
- 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 $::os_service_default
- barbican_auth_endpoint
-
(optional) Keystone v3 API URL. Example: localhost:5000/v3 Defaults to $::os_service_default
- barbican_endpoint
-
(optional) Barbican URL. Defaults to $::os_service_default
- barbican_api_version
-
(optional) Barbican API version. Defaults to $::os_service_default

-
(optional) Maximum number of live migrations to run in parallel. Defaults to $::os_service_default
- sync_power_state_pool_size
-
(optional) Maximum number of greenthreads to use when syncing power states. Defaults to $::os_service_default
- 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 $::os_service_default
- consecutive_build_service_disable_threshold
-
(optional) Max number of consecutive build failures before the nova-compute will disable itself. Defaults to $::os_service_default
- keymgr_backend
-
(optional) Key Manager service class. Example of valid value: castellan.key_manager.barbican_key_manager.BarbicanKeyManager Defaults to ‘nova.keymgr.conf_key_mgr.ConfKeyManager’.
- verify_glance_signatures
-
(optional) Whether to verify image signatures. (boolean value) Defaults to $::os_service_default
- reserved_huge_pages
-
(optional) Number of huge memory pages to reserved per NUMA host cell. Defaults to $::os_service_default Accepts a string e.g “node:0,size:1GB,count:4” or a list of strings e.g:
- “node:0,size:1GB,count:4”, “node:1,size:1GB,count:4”
- neutron_physnets_numa_nodes_mapping
-
(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 []
- live_migration_wait_for_vif_plug
-
(optional) whether to wait for “network-vif-plugged“ events before starting guest transfer Defaults to $::os_service_default
- 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 $::os_service_default
DEPRECATED PARAMETERS
- vnc_keymap

This option has been superseded by the “cpu_shared_set“ and “cpu_dedicated_set“ options, which allows co-existence of pinned and unpinned instances on the same host. Defaults to undef
