Tal - is there any reason why a diskattachments link was not added to StorageDomainTemplateService in the first place, or is it just a missing feature?

Thanks, Idan. I know that export domain is deprecated. But for now, we're still using it in our project.
And we need to know which one is the bootable disk of vm/template in export domain for security checking.
Diskattachments link is available for vm in export domain, but templates miss the diskattachments link.
That's why i want to add the diskattachments link for templates in export domain.
Or is there any convenient way to know which one is the bootable disk of template in export domain?
Not that I know of.

Regards.

The API of the engine is specified by [1].
Specifically, what you're looking for is StorageDomainTemplateService [2].
However, I am not sure that it's worth adding features to the export domain as I think that it's going to be (or already) deprecated.

Daniel/Tal?

Hi, Idan. 
I have one more question. There is no diskattachments link for template in export storage domain. 
So i want to add the diskattachments link for it. I tried to read the source code in ovirt-engine project.
BackendStorageDomainTemplateResource defines some methods of StorageDomainTemplate. 
It implements the interface org.ovirt.engine.api.resource.StorageDomainTemplateResource.
But i can't find where is the location of org.ovirt.engine.api.resource.StorageDomainTemplateResource.
Could you please tell me where i can find the source code of StorageDomainTemplateResource?

Thanks

Regards.

Thanks a lot. You're right, something is indeed wrong. From your reply, i suddenly realized that maybe some configuration is not right. And finally i find that my colleague added ENGINE_API_DEFAULT_VERSION=3 in the configuration file for his own experiment, but he didn't notify us. Now i delete the configuration item, everything is fine.

Sounds like something's wrong.
I've just checked 4.1.9 and I do have the diskattachments link under a specific template.
Can you say what you do have under /ovirt-engine/api/templates/<template_id>?
This is the output I get in 4.1.9 under ovirt-engine/api/templates/00000000-0000-0000-0000-000000000000/ (pasting only the links):

In my oVirt 4.1.9 env, vm's api is fine. I can get vm's diskattachments from /ovirt-engine/api/vms/<vm_id>/diskattachments. 
But for template, i got an error(404 not found) from /ovirt-engine/api/templates/<template_id>/diskattachments.

Actually, it was added back in oVirt 4.0.
What happens when you try to GET from /ovirt-engine/api/templates/<template_id>/diskattachments?
Do you get an empty list of attachments or an error (404 not found)?

Thank you for your reply. 
I'm using ovirt 4.1.9, in this version there is no diskattachments under /ovirt-engine/api/templates/<template_id>, is it added in oVirt4.2?

Hi,

The bootable attribute was moved, along with a few more attributes, to be under a specific diskattachment, as it is an attribute of the relationship between a disk and the specific VM it is attached to, rather than a disk (which can be floating, or attached to more than one VM).
I am not sure that I understand the question. A template does have diskattachments under /ovirt-engine/api/templates/<template_id>/diskattachments.
Which engine's version are you using?

Idan

Hi All,

In the restapi of version 3, there is bootable attribute  in disk. But in version 4, the bootable attribute is removed from disk. For vm i can get bootable attribute from diskattachment. But there is no diskattachment in template. So, is there any way in the restapi of version 4 that i can know if the disk of the template is bootable or not?

Thanks

Regards.
