exclude_devices = []

list value

Comma-separated list of <network_device>:<vfs_to_exclude> tuples, mapping network_device to the agent’s node-specific list of virtual functions that should not be used for virtual networking. vfs_to_exclude is a semicolon-separated list of virtual functions to exclude from network_device. The network_device in the mapping should appear in the physical_device_mappings list.

physical_device_mappings = []

list value

Comma-separated list of <physical_network>:<network_device> tuples mapping physical network names to the agent’s node-specific physical network device interfaces of SR-IOV physical function to be used for VLAN networks. All physical networks listed in network_vlan_ranges on the server should have mappings to appropriate interfaces on each agent.

resource_provider_bandwidths = []

list value

Comma-separated list of <network_device>:<egress_bw>:<ingress_bw> tuples, showing the available bandwidth for the given device in the given direction. The direction is meant from VM perspective. Bandwidth is measured in kilobits per second (kbps). The device must appear in physical_device_mappings as the value. But not all devices in physical_device_mappings must be listed here. For a device not listed here we neither create a resource provider in placement nor report inventories against. An omitted direction means we do not report an inventory for the corresponding class.

resource_provider_hypervisors = {}

dict value

Mapping of network devices to hypervisors: <network_device>:<hypervisor>,…​ hypervisor name is used to locate the parent of the resource provider tree. Only needs to be set in the rare case when the hypervisor name is different from the DEFAULT.host config option value as known by the nova-compute managing that hypervisor.

resource_provider_inventory_defaults = {'allocation_ratio': 1.0, 'min_unit': 1, 'reserved': 0, 'step_size': 1}

dict value

Key:value pairs to specify defaults used while reporting resource provider inventories. Possible keys with their types: allocation_ratio:float, max_unit:int, min_unit:int, reserved:int, step_size:int, See also: https://docs.openstack.org/api-ref/placement/#update-resource-provider-inventories
