**Table 6** **os_extra_specs** field description
Parameter	Type	Description

resource_type	String	Specifies the resource type. resource_type is used to differentiate between the types of the physical servers accommodating ECSs.
instance_vnic:type	String	Specifies the NIC type. The value of this parameter is consistently enhanced, indicating that network enhancement ECSs are to be created.
instance_vnic:instance_bandwidth	String	Specifies the maximum bandwidth in the unit of Mbit/s. The maximum value of this parameter is 10000.
instance_vnic:max_count	String	Specifies the maximum number of NICs. The maximum value of this parameter is 4.
quota:local_disk	String	The value of this parameter is in format of "{type}:{count}:{size}:{safeFormat}", where, type: indicates the disk type, which can only be HDD. count: indicates the number of local disks. For D2 ECSs, the value can be 2, 4, 8, 12, 16, or 24. For D3 ECSs, the value can be 2, 4, 8, 12, 16, 24, or 28. size: indicates the capacity of a single disk, in GB. Currently, only 1675 is supported. The actual disk size is 1800, and the available size after formatting is 1675. safeFormat: indicates whether the local disks of the ECS are securely formatted. For D2 or D3 ECSs, the value is True. NOTE: This field is dedicated for disk-intensive ECSs.
quota:nvme_ssd	String	The value of this parameter is in the format of {type}:{spec}:{num}:{size}:{safeFormat}:. type: indicates the capacity of a single NVME SSD disk attached to the ECS, which can only be 1.6 TB or 3.2 TB. spec: indicates the specification of the NVME SSD disk, which can be large or small. If the value is large, only I3 ECSs are supported. num: indicates the number of partitions on the disk. size: indicates the capacity, in the unit of GB, of the disk used by the guest user. If the spec value is large, the value of this parameter is the size of a single disk attached to the ECS. If the spec value is small, the value of this parameter is 1/4 or 1/2 of the specification. safeFormat: indicates whether the local disks of the ECS are securely formatted. If the value is True, only I3 ECSs are supported. NOTE: This field is dedicated for ultra-high I/O ECSs.
ecs:generation	String	Specifies the generation of an ECS type. For example, 3 in s3 indicates the general-purpose third-generation ECSs. For details about flavors and generations, see ECS Specifications in Elastic Cloud Server User Guide.
ecs:virtualization_env_types	String	Specifies a virtualization type. If the parameter value is FusionCompute, the ECS uses Xen virtualization. Currently, the Xen virtualization technology is not supported. If the parameter value is CloudCompute, the ECS uses KVM virtualization. NOTE: This field is optional.
pci_passthrough:enable_gpu	String	Indicates whether the GPU is passthrough. If the value is true, the GPU is passthrough.
pci_passthrough:alias	String	Indicates the model and quantity of passthrough-enabled GPUs on P1 ECSs. The parameter value can be set to nvidia-p100:1, indicating that the ECS using this specification will occupy one NVIDIA P100 GPU.
cond:operation:status	String	This parameter takes effect region-wide. If an AZ is not configured in the cond:operation:az parameter, the value of this parameter is used by default. If this parameter is not set or used, the meaning of normal applies. Options: normal: indicates normal commercial use of the flavor. abandon: indicates that the flavor has been canceled (not displayed). sellout: indicates that the flavor has been sold out. obt: indicates that the flavor is under open beta testing (OBT). obt_sellout: indicates that the OBT resources are sold out. promotion: indicates the recommended flavor (commercial use, which is similar to normal).
cond:operation:az	String	This parameter takes effect AZ-wide. If an AZ is not configured in this parameter, the value of the cond:operation:status parameter is used by default. This parameter is in the format of "az(xx)". The value in parentheses is the flavor status in an AZ. If the parentheses are left blank, the configuration is invalid. The cond:operation:az options are the same as the cond:operation:status options. For example, a flavor is for commercial use in AZs 0 and 3, sold out in AZ 1, for OBT in AZ 2, and is canceled in other AZs. Then, set parameters as follows: cond:operation:status: abandon cond:operation:az: az0(normal), az1(sellout), az2(obt), az3(normal) NOTE: Configure this parameter if the flavor status in an AZ is different from the cond:operation:status value.
quota:max_rate	String	Specifies the maximum bandwidth. Unit: Mbit/s. If a bandwidth is in the unit of Gbit/s, it must be divided by 1000.
quota:min_rate	String	Specified the assured bandwidth. Unit: Mbit/s. If a bandwidth is in the unit of Gbit/s, it must be divided by 1000.
quota:max_pps	String	Specifies the maximum intranet PPS. Unit: number. If a value is in the unit of 10000, it must be divided by 10000.
cond:operation:charge	String	Specifies a billing type. Both billing types are supported if this parameter is not set. Pay-per-use
cond:compute	String	Specifies computing constraints. autorecovery: indicates that automatic recovery is supported. If this parameter does not exist, automatic recovery is not supported.
