Hi @kagbasi-ngc,
The "VM Lacks Feature" message typically means the VM is missing a functional agent required for migration, so it's likely not related to the load balancer.
To keep things clear and easier to follow, I suggest opening a separate thread for unrelated issues. It helps us stay focused and makes it easier to assist everyone effectively.
Regarding XO reconnecting: this behavior can occur if previous host connection details are still present in the configuration. Since Xen Orchestra doesn’t perform any kind of autodiscovery, this usually points to a misconfiguration—most often when multiple hosts from the same pool are added manually under Settings > Servers.
Lastly, about the related topic you mentioned—yes, the certificate is likely the root cause of that particular issue.
