Querying Details About extra_specs Parameters of a BMS Flavor (Native OpenStack API)

Function

extra_specs parameters specify the key-value pair of a BMS flavor. For example, baremetal:extBootType specifies the boot device of the BMS. Its value can be LocalDisk (local disk) or Volume (EVS disk). If you want to check whether a flavor supports quick provisioning, you can call this API.

URI

GET /v2.1/{project_id}/flavors/{flavor_id}/os-extra_specs

Table 1 lists the parameters.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the project ID, see Obtaining a Project ID.
flavor_id	Yes	Specifies the flavor ID. You can obtain the flavor ID from the BMS console or using the Querying BMS Flavors (Native OpenStack API) API.

Response

Response parameters

Parameter	Type	Description
extra_specs	Object	Specifies the key-value pair of a BMS flavor. capabilities:cpu_arch: specifies the CPU architecture of the BMS. The value can be x86_64 (for x86 servers) or aarch64 (for ARM servers). baremetal:disk_detail: specifies the disk description. capabilities:hypervisor_type: specifies the hypervisor type. The value is fixed at ironic. baremetal:__support_evs: specifies whether to support EVS disks. The value can be true or false. If the flavor does not contain this parameter, EVS disks are not supported either. baremetal:extBootType: specifies the boot device of the BMS. The value can be LocalDisk (local disk) or Volume (EVS disk). baremetal:net_num: specifies the number of NICs that can be attached to a BMS. baremetal:netcard_detail: specifies description of the NIC. baremetal:cpu_detail: specifies description of the CPU. resource_type: specifies the resource type. The value is fixed at ironic. baremetal:memory_detail: specifies description of the memory.
