Create VM using REST API in OLVM

I have added a disk under a storage domain in OLVM and I am trying to attach that disk while creating a VM using "/ovirt-engine/api/vms" with below payload. But I am getting the input payload is syntactically incorrect message:

Can you please provide the sample json to attach a disk while creating VM:
