There are two types of guest

 - Persistent: This has a config file on disk. It will appear 
   either in the ListDefinedDomains or ListDomains, depending
   on whether it is currently running
 - Transient: This has *no* config on disk. It will only appear
   in ListDomains and will disappear completely when it is
   shutdown.

Every inactive domain is thus a persistent domain. A running domain can
be either transient or persistent. There is a virDomainIsPersistent()
API to distinguish them.
