The Libvirt Agents plugin is unable to generate valid Jenkins Configuration as Code (JCasC) for its agents.
An exception appears in the generated YAML:

To reproduce:
- Have "Libvirt Plugin" installed & configured with at least one agent added
- Click "Manage Jenkins"
- Click "Configuration as Code"
- Click "View Configuration"
- Generated JCasC will show the above error for Libvirt Agents

Expected: Valid YAML is generated and can be applied in order to create nodes via JCasC.
[JENKINS-72362] Unable to export agents as JCasC

added a comment - Thank you for the fix, m_jeanson!
My upgrade experience went as follows:
After upgrading to the latest version and running a job all VMs failed to initialize due to:
ERROR: Issue with creating launcher for agent Fedora-39. The agent has not been fully initialized yet Fedora-39 was marked offline: Disconnected by SYSTEM : Reverting to snapshot "BuildImage"
Navigating to an agent's configuration in the GUI and then saving the configuration (without making any changes) fixed the issue. Comparing the JCasC showed that broken agents had 'waitingTimeSecs: 0' while a working agent had 'waitingTimeSecs: 60'. I recall using Jenkins "Manage Old Data" feature to clean something and I think it was related to wait time in the VMs. The issue was easily worked around by configuring each agent with a wait time.
Now, Jenkins was able to generate a JCasC file for the agents, but Jenkins failed to actually load from the generated JCasC (partial stack trace follows):
java.lang.NullPointerException at java.base/java.util.ArrayList.<init>(ArrayList.java:179) at hudson.util.CopyOnWriteList.replaceBy(CopyOnWriteList.java:130) at hudson.util.PersistedList.replaceBy(PersistedList.java:95) at hudson.model.Slave.setNodeProperties(Slave.java:311) at hudson.plugins.libvirt.VirtualMachineSlave.<init>(VirtualMachineSlave.java:96) Caused: java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.base/java.lang.reflect.Constructor.newInstance(Constructor.java:490) at io.jenkins.plugins.casc.impl.configurators.DataBoundConfigurator.tryConstructor(DataBoundConfigurator.java:181) Caused: io.jenkins.plugins.casc.ConfiguratorException: virtualMachineSlave: Failed to construct instance of class hudson.plugins.libvirt.VirtualMachineSlave.

Arguments: [java.lang.String, null, java.lang.String, java.lang.String, hudson.model.Node$Mode, java.lang.String, hudson.plugins.libvirt.VirtualMachineLauncher, hudson.slaves.JNLPLauncher, hudson.slaves.RetentionStrategy$Always, null, java.lang.String, java.lang.String, java.lang.String, java.lang.Integer, java.lang.String, java.lang.Boolean, java.lang.Integer, java.lang.String]. Expected Parameters: name java.lang.String, nodeDescription java.lang.String, remoteFS java.lang.String, numExecutors java.lang.String, mode hudson.model.Node$Mode, labelString java.lang.String, launcher hudson.plugins.libvirt.VirtualMachineLauncher, delegateLauncher hudson.slaves.ComputerLauncher, retentionStrategy hudson.slaves.RetentionStrategy<? extends hudson.model.Computer>, nodeProperties java.util.List<? extends hudson.slaves.NodeProperty<?>>, hypervisorDescription java.lang.String, virtualMachineName java.lang.String, snapshotName java.lang.String, startupWaitingPeriodSeconds int, shutdownMethod java.lang.String, rebootAfterRun boolean, startupTimesToRetryOnFailure int, beforeJobSnapshotName java.lang.String
Comparing 'Arguments' and 'Expected Parameters' showed that Jenkins was failing to initialize the VMs because it was missing 'nodeDescription' and 'nodeProperties' arguments. None of my agents had a node description, so I added one. As for the "node properties", I just added in 'nodeProperties: []' manually to the JCasC. These two changes made Jenkins properly bring up the VMs!
I'll file a separate bug for the 'nodeDescription' and 'nodeProperties' issue.
