https://jira.opendaylight.org This file is an XML representation of an issue en-us 8.20.10 820010 22-06-2022 https://jira.opendaylight.org/browse/NEMO-4 nemo <p>When testing the NIC BoD flow, a VNMappingException is thrown intermittently.</p> <p>To reproduce: </p> <p>Build and run karaf from the NIC project. Then:</p> <p>feature:install odl-nic-core-service-mdsal odl-nic-renderer-nemo</p> <p>Then run the following scripts from NEMO in sequence:</p> <p>nemo-impl/src/main/resources/nemo-odl.py<br/> nemo-impl/src/test/resources/nic-bod-setup.py<br/> nemo-impl/src/test/resources/nic-bod-intent.py</p> <p>Note that an "IntentResolutionException: The physical hosts do not exist." exception is expected when first running nic-bod-setup.py. This is expected and is not what this issue is about. </p> <p>The issue is that:</p> <p>Intermittently, upon running nic-bod-intent.py the following exception is thrown:</p> <p>org.opendaylight.nemo.intent.computation.VNMappingException: Failed mapping for the virtual link 1655f574-04f1-487b-8337-a27a0cefc60c in the virtual network 14ce424a-3e50-4a2a-ad5c-b29845158c8b<br/> at org.opendaylight.nemo.intent.computation.VNMappingUnit.virtualNetworkMapping(VNMappingUnit.java:208)<br/> at org.opendaylight.nemo.intent.IntentResolver.resolveIntent(IntentResolver.java:400)<br/> at org.opendaylight.nemo.user.UserManager.endTransaction(UserManager.java:128)<br/> at org.opendaylight.yangtools.yang.binding.util.RpcMethodInvokerWithInput.invokeOn(RpcMethodInvokerWithInput.java:30)<br/> at org.opendaylight.yangtools.yang.binding.util.AbstractMappedRpcInvoker.invokeRpc(AbstractMappedRpcInvoker.java:52)<br/> at org.opendaylight.controller.md.sal.binding.impl.BindingDOMRpcImplementationAdapter.invoke(BindingDOMRpcImplementationAdapter.java:85)<br/> at org.opendaylight.controller.md.sal.binding.impl.BindingDOMRpcImplementationAdapter.invokeRpc(BindingDOMRpcImplementationAdapter.java:72)<br/> at org.opendaylight.controller.md.sal.dom.broker.impl.GlobalDOMRpcRoutingTableEntry.invokeRpc(GlobalDOMRpcRoutingTableEntry.java:40)<br/> at org.opendaylight.controller.md.sal.dom.broker.impl.DOMRpcRoutingTable.invokeRpc(DOMRpcRoutingTable.java:186)<br/> at org.opendaylight.controller.md.sal.dom.broker.impl.DOMRpcRouter.invokeRpc(DOMRpcRouter.java:124)<br/> at org.opendaylight.controller.md.sal.binding.impl.RpcServiceAdapter.invoke0(RpcServiceAdapter.java:65)<br/> at org.opendaylight.controller.md.sal.binding.impl.RpcServiceAdapter.access$000(RpcServiceAdapter.java:43)<br/> at org.opendaylight.controller.md.sal.binding.impl.RpcServiceAdapter$RpcInvocationStrategy.invoke(RpcServiceAdapter.java:159)<br/> at org.opendaylight.controller.md.sal.binding.impl.RpcServiceAdapter.invoke(RpcServiceAdapter.java:96)<br/> at com.sun.proxy.$Proxy87.endTransaction(Unknown Source)<br/> at org.opendaylight.nic.nemo.renderer.NEMORenderer.endTransaction(NEMORenderer.java:217)<br/> at org.opendaylight.nic.nemo.renderer.NEMORenderer.executeNemoRpc(NEMORenderer.java:172)<br/> at org.opendaylight.nic.nemo.renderer.NEMORenderer.createOrUpdateIntent(NEMORenderer.java:186)<br/> at org.opendaylight.nic.nemo.renderer.NEMORenderer.create(NEMORenderer.java:100)<br/> at org.opendaylight.nic.nemo.renderer.NEMORenderer.onDataChanged(NEMORenderer.java:89)<br/> at org.opendaylight.controller.md.sal.binding.impl.AbstractForwardedDataBroker$TranslatingDataChangeInvoker.onDataChanged(AbstractForwardedDataBroker.java:143)<br/> at org.opendaylight.controller.cluster.datastore.DataChangeListener.dataChanged(DataChangeListener.java:66)<br/> at org.opendaylight.controller.cluster.datastore.DataChangeListener.handleReceive(DataChangeListener.java:39)<br/> at org.opendaylight.controller.cluster.common.actor.AbstractUntypedActor.onReceive(AbstractUntypedActor.java:34)<br/> at akka.actor.UntypedActor$$anonfun$receive$1.applyOrElse(UntypedActor.scala:167)<br/> at akka.actor.Actor$class.aroundReceive(Actor.scala:467)<br/> at akka.actor.UntypedActor.aroundReceive(UntypedActor.scala:97)<br/> at akka.actor.ActorCell.receiveMessage(ActorCell.scala:516)<br/> at akka.actor.ActorCell.invoke(ActorCell.scala:487)<br/> at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:238)<br/> at akka.dispatch.Mailbox.run(Mailbox.scala:220)<br/> at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(AbstractDispatcher.scala:397)<br/> at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:262)<br/> at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:975)<br/> at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1478)<br/> at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:104)</p> <p>Operating System: All<br/> Platform: All<br/> URL: <a href="https://git.opendaylight.org/gerrit/#/c/33076/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/33076/</a></p> NEMO-4
