For example, if libvirt is started really early at boot time and the hostnames cannot be resolved by the DNS yet, they will pass the check but they will disappear on libvirtd restart. The hostname->ip pairings are not stable either, so if we do this, I think it should be done on pool startup, not config parsing. > - return STREQ(poolsrc->hosts[0].name, defsrc->hosts[0].name); > + if (STRNEQ(poolsrc->hosts[0].name, defsrc->hosts[0].name)) { > + /* Matching just a name isn't reliable as someone could provide > + * the name for one pool and the IP Address for another pool, so Resolving them is IMHO just as unreliable. Re: the original bug - is it possible to check that we have connected to a session with a different hostname than what we requested? Or just disallow starting two pools with the same targetname, since they are supposed to be unique? Jan
