Created attachment 1222354 [details] engine logs Description of problem: In environment with more than one storage domain, and diskless VM. After detaching one storage domain from the environment, the VM remain in the data-center but after the storage-domain attached back, the VM can be registered from it. Version-Release number of selected component (if applicable): Engine - 4.0.6-0.1.el7ev How reproducible: 100% Steps to Reproduce: 1. Create 2 storage-domains 2. Create a VM without disks 3. Detach one of the storage-domains 4. Attach the storage-domain from step 3 back to the data-center 5. Try to import the VM from step 2. Actual results: Failed to import the VM back since it's already exist Expected results: VM should not appear as available for registration. Additional info: Engine logs attached
Basically, we don't have any obligation not to show unregistered entities in a storage domain even if they are already registered in the system. Looking at the code it looks like this was always worked like this (even with VMs containing disks on separate storage domains). because of that reason I don't think it is a bug, although since you marked it as a regression I'm interesting to see what was the behavior before and when it was changed

The behavior should be consistent and unregistered entities should still get presented even if they are already registered in the engine. The validation, how ever should block the entity from being registered twice. Allon, is there any other reason you think we should filter out unregistered entities, or can we close this bug?
As we consistent with unregistered vms behavior (diskless or not) and we don't have any RFE requesting filtering. I'm closing this won't fix.
Eyal, I remember you open this because the documentation says this should not be allowed. Please refer to the place it is written so the documentation will change accordingly
http://www.ovirt.org/develop/release-management/features/engine/importunregisteredentities/ : - On detach of Storage Domain the VMs/Templates related to the Storage Domain should be deleted from the engine, but their data will be converted to an XML data which will be preserved in a DB table called unregistered_ovf_of_entities, and will still be part of the OVF disk contained in the Storage Domain. -> add that an exception about diskless VM, Stay at the engine after storage domain detached. I didn't find any reference to VM without disks in the documentations.
