Looking the API, the Disk type has element 'vms', but we don't feed it
with data:

https://github.com/oVirt/ovirt-engine-api-model/blob/master/src/main/java/types/Device.java#L50

I can fix the API so it returns it. So feel free to open a bug if you
need it.

OK. Thanks.

But maybe, can you describe your exact use case? You user just input
disk 'id' and you are suppose to return the VM which it's attached to?

Take 2 cases for examples:

1. Updating the attributes of a disk needs to also update the corresponding disk-attachment, which requires the vm id to initialize the VMService. The code shows as blow:

`connnection.SystemService().VMsService().VMService(vmid).DiskAttachmentsService().Update()`.

2. Deleting a disk needs to make sure all the VMs it's attached to have been powered down (if not, we could directly power down them). Then we could detach the disk for each VM and removes the disk finally.

If you need to know only if it's attached 'true/false', you can use

/api/disks?search=number_of_vms=1

Hi Ondra,

I tried your URL but it not worked. I want to retrieve all the attached vms by a disk, so I cloud not provide a specified vm name for searching. Also tried with https://fqdn/ovirt-engine/api/vms?search= <https://fqdn/ovirt-engine/api/disks?search=vm_names=myvmname>_disk=DISKNAME_, unfortunately the `disk` parameter is not supported.

Put it differently, how could I get the disk list by rest API as same as shown by visiting admin portal at https://fqdn/ovirt-engine/webadmin/?#disks, which indicates the attached vm name for each disk.

OK, got it. Search is a powerful solution. Thank you very much.

Hi all,

I use oVirt engine API v4.2 for implementing terraform oVirt
provider. And I want to check if a Disk has been attached to
a VM, so I need to find all vms attached by this disk.
But after I checked the GET-Response data from the
"/ovirt-engine/api/disks/<disk-id>" rest url, there has no
disk-attachment/vm related properties or links. I could get
a trade-off, by the following steps:
1. getting all vms
2. get all disk-attachments of each vm
3. check if the given disk id equals to the `disk` property
of each disk-attachment`
4. If equals, append the vm to result list

Is there any simpler and smarter way to get this? Thanks.

Hi, you can use following:

https://fqdn/ovirt-engine/api/disks?search=vm_names=myvmname
<https://fqdn/ovirt-engine/api/disks?search=vm_names=myvmname>
