----------------------------------------
Patch was tested using rhevm with multiple datacenters and two realms
(clusters) in the datacenter under test. The API commands and output are copied
below:

> RHEV-M: We need to skip 'default' cluster when no 'realm_id' is specified in

> URL: https://issues.apache.org/jira/browse/DTACLOUD-126
> Project: DeltaCloud
> Issue Type: Bug
> Components: Server
> Reporter: Michal Fojtik
> Assignee: Michal Fojtik
> Priority: Blocker
> Attachments:
> 0001-RHEV-M-Choose-the-image-realm-when-no-realm-is-being.patch
>
>
> When there is no realm_id provided upon creating a new instance, by default
> Deltacloud will choose the first 'realm' returned by 'realms' call.
> In RHEV-M it usually means that the 'default' cluster is being returned,
> which is wrong in most cases, since this cluster is being used for
> holding the 'Blank' template, thus cannot be removed. This cluster usually
> don't have 'storage domain' assigned and deploying an instance
> there lead to error.
> The solution could to to 'skip' default realm and try to use next realm in
> row (if there is next realm). If there is just 'default' realm, we should
> choose this realm and additionally give client decent error :-)
