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

[Gadi Ickowicz]

I have no experience using JSON myself (I use XML when using REST), however, note that the storage_domain is a list of ids, inside of a storage_domains object. Maybe try to send a request formatted like that?

Juan - any other insights?

Subject: [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
