1. Set a primary storage and cluster for the root volume.

   "allocate": {
       "primaryStorage": {
         "type": "Enter a primary storage type. Valid values: Ceph, LocalStorage, NFS, and SharedBlock.",
         "uuid": "Enter a primary storage UUID.",
         "poolNames": [
           "Enter the name of a Ceph pool. Delete this parameter if you do not specify a Ceph primary storage."
         ]
       }
       "clusterUuid":"Enter a cluster UUID."
     }

   • type: Enter a primary storage type. Valid values: Ceph, LocalStorage, NFS, and SharedBlock. If you specify a Ceph primary storage, you can specify a Ceph pool.
   • uuid: Enter a primary storage UUID.
   • poolNames: Enter the name of a Ceph pool. Delete this parameter if you do not specify a Ceph primary storage.
   Note: If you do not need to specify a primary storage or a cluster, delete the corresponding codes.
2. Set a billing type for the root volume.

   "priceUserConfig": {
       "rootVolume": {
         "priceKeyName": "Set a billing name for the root volume. Make sure that advanced parameter setting in the pricing list is consistent with this setting. Otherwise, the corresponding billing entries cannot be generated."
       }
     }

   • priceKeyName: Set a billing name for the root volume. Make sure that advanced parameter setting in the pricing list is consistent with this setting. Otherwise, the corresponding billing entries cannot be generated.
   Note: If you do not need billing settings, delete the preceding parameter settings.
3. Set the display attribute of the root volume.

   "displayAttribute": {
       "rootVolume": {
         "diskType": "Set the display type for the root volume. You can view this parameter setting on the VM details page."
       }
     }

   • rootVolume: Set the display type for the root volume. You can view this parameter setting on the VM details page. You can also set multiple attributes in key-value pair format.
   Note: If you do not need special display, delete the corresponding codes.
