That's correct. In your case all known VMs are running. > Is this some kind of bug because as per my understanding listDefinedDomains > should return a superset of vm's as returned by listDefinedDomains(). listDefinedDomains doesn't return a superset, it just returns the list of known but non-running VMs, it doesn't return all known VMs. To get the list of all known VMs you need to combine the lists returned by listDomainsID and listDefinedDomains.
