>          Components: EC2/Frontend, Server
>         Environment: Fedora 17, Deltacloud 1.0.3

>
> When performing actions with RHEV-M driver, and EC2 frontend, oVirt returns only a status object, and not the original resource, or link to get the updated resource.
> Thus, in the EC2 frontend, an error 500 is returned, as no ID is found in the oVirt returned object, which causes a failure.
> Several solutions may apply here (until a more suitable resource is returned by oVirt):
> 1. Returning the original resource.
> 2. Returning a new response object, with the status returned by oVirt, and in addition the link to the resource we did the action on.
