Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Previously, when a vNIC had two references to a VM, if the VM is a template, one reference was used. Otherwise, the other reference was used. This construct confused the constraint checker of the database and enabled inconsistencies. Bug 1528316 and bug 1684586 disabled the check of this constraint during upgrades. The current release fixes this issue by merging both references into a single one, which has to be set. As a result, the improved data structure in the database matches the database constraints and prevents inconsistencies.

Description RHV bug bot 2019-03-14 12:34:20 UTC 
+++ This bug is an upstream to downstream clone. The original bug is: +++
+++   bug 1547038 +++
======================================================================

+++ This bug was initially created as a clone of Bug #1528316 +++


As explained in https://bugzilla.redhat.com/show_bug.cgi?id=1528316#c4 our vm_interface has two fields (vm_guid and vmt_guid) referring to the same table, and we should eliminate this.

Is this a bug or a feature?

Comment 4 RHV bug bot 2019-03-14 12:34:31 UTC 
This is technical debt of normalizing the db and aligning the engine accordingly, with no customer facing effects (hopefully...)

This seems like a risky change with limited benefit, therefore for now.

Steps to Reproduce on oVirt 4.3:
1. Create a VM with a vNIC
2. Create a template of this VM
3. Create a subversion of the template
4. Run engine-setup


Actual results:
[ INFO  ] Checking the Engine database consistency
[ ERROR ] Failed to execute stage 'Setup validation': Failed checking Engine database: an exception occurred while validating the Engine database, please check the logs for getting more info:
         Constraint violation found in  vm_interface (vmt_guid) |1


Expected results:
engine-setup succeeds

Removing CodeChange and updating title as this is an upgrade blocker

Ahh, sorry I've missed that we have BZ1684586 to track that issue in 4.3
