[ovirt-users] Attaching storage to VM via JSON REST

Hi all, I'm exploring using ovirt's REST APIs to manage VM creation/deletion/etc. I can create the VM, attach an ISO and change boot order, but I'm unable to attach a storage disk to the VM. I send a POST request to /api/vms/<vm uuid>/disks with the structure: {"storage_domain": {"name":"am_data", "id":"6fbee79d-5b71-48c1-b86c-ee9755a46013" }, "size":"4294967296", "type":"system", "interface":"ide", "format":"raw", "sparse":"false", "bootable":"true", "wipe_after_delete":"false" } The response I receive is { "reason" : "Operation Failed", "detail" : "[Cannot add Virtual Machine Disk. Storage Domain doesn't exist.]" } For the storage domain, I've tried just the name, just the id, and both with the same results. When I attach storage from the GUI, the disk is created/attached fine, and a GET request for the disks of the VM shows the storage domain as the same as I was attempting to use before. "storage_domains" : { "storage_domain" : [ { "id" : "6fbee79d-5b71-48c1-b86c-ee9755a46013" } ] }, Any idea what I might be doing wrong? Thanks, Andrew
