the daemon should try to figure out the "fully qualified domain name", FQDN.
-This is done using a lookup of the name returned by C<gethostname>.

-Using this feature (i.E<nbsp>e. setting this option to B<true>) is recommended.
-However, to preserve backwards compatibility the default is set to B<false>.
-The sample config file that is installed with C<makeE<nbsp>install> includes a
-line which sets this option, though, so that default installations will have

-If enabled, translate the disk names to major/minor device numbers
-(e.E<nbsp>g. "8-0" for /dev/sda). For backwards compatibility this defaults to
-I<true> but it's recommended to disable it as it will probably be removed in
-the next major version.

+
+When the libvirt plugin logs interface data, it sets the name of the collected

+the hypervisor (the "dev" property of the target node), which is equal to
+setting B<name>.
+
+B<address> means use the interface's mac address. This is useful since the
+interface path might change between reboots of a guest or across migrations.
