Description of problem: Can't update cluster's MAC pool if the cluster contain template with vNIC We get a null pointer exception when trying to update a cluster with another MAc pool range and if the cluster contain temlate with vNIC or vNICs. 2020-09-22 10:10:32,597+03 ERROR [org.ovirt.engine.core.bll.UpdateClusterCommand] (default task-44) [f1816eec-abdb-495b-840b-9098e6f3a35d] Error during ValidateFailure.: j ava.lang.NullPointerException: element cannot be mapped to a null key at java.base/java.util.Objects.requireNonNull(Objects.java:246) at java.base/java.util.stream.Collectors.lambda$groupingBy$53(Collectors.java:1127) at java.base/java.util.stream.ReduceOps$3ReducingSink.accept(ReduceOps.java:169) at java.base/java.util.ArrayList$ArrayListSpliterator.forEachRemaining(ArrayList.java:1655) at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:484) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:474) at java.base/java.util.stream.ReduceOps$ReduceOp.evaluateSequential(ReduceOps.java:913) at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) at java.base/java.util.stream.ReferencePipeline.collect(ReferencePipeline.java:578) Version-Release number of selected component (if applicable): rhvm-4.4.3.3-0.19.el8ev.noarch How reproducible: 100% Steps to Reproduce: 1. Have a cluster with VM and template with vNIC 2. Create new MAC pool range 3. Try to edit the cluster and assign it with new MAC pool range Actual results: null pointer exception in engine log Expected results: Must work Additional info: Most probably related to this patch https://gerrit.ovirt.org/#/c/98357/ The patch changed the data model, which might have introduced this bug.
