In libvirt-php: libvirt_list_domains() returns an array of all domain resource; libvirt_list_active_domains() returns an array of running domain ids; libvirt_list_defined_domains() returns an array of defined domain names. and libvirt_list_storagepools() returns an array of actived storagepool names. In my opinion, returning an array of names would be better when listing all kinds of objects. And the naming convenances, let's take domains as an example. libvirt-php provied libvirt_list_domains() for all domains, which has no corresponding function in libvirt. libvirt_list_active_domains() for running domains, corresponding to virConnectListDomains() in libvirt. libvirt_list_defined_domains() for defined domains, corresponding to virConnectListDefinedDomains() in libvirt. I believe it is fine. However, for defined objects, sometimes it used term "defined" (libvirt_list_defined_domains), and sometimes use term "inactive" (libvirt_get_inactive_domain_count) in contrast to "active". Which would be better? </blockquote> </div></div> Not sure if I get the meaning correctly, and also not sure what the exact meaning of "active" and "inactive" are in libvirt-php, but I guess: 1) "active" and "inactive" are about the domain state. 2) "defined" is about if it the domain has persistent config file on disk. So, if guessing 1) is right: A "defined" domain can be in either of "active" and "inactive" state; And an "active" domain can be "defined" or "not defined", and it's the same for "inactive" domain. Any conflict? Regards Osier </blockquote></div> What about the "actived" & "defined" in libvirt? As far as I know, virConnectListDefinedDomains() will list domains which isn't running and has persistent config file on disk "defined" in libvirt-php should have same meaning with libvirt, since the implementation of libvirt_list_defined_domains() is just a wrapper of virConnectListDefinedDomains(), and libvirt_get_inactive_domain_count() is a wrapper of virConnectNumOfDefinedDomains().
