[libvirt] [RFC] why netcf/libvirt lists/dumpxml only unslaved/unsubordinated interfaces?
It could be useful to dumpxml of slaves/subordinates too to introspect host interfaces tree in dephts. Now it is not possible: 'Interface eth0 does not exist or is not a toplevel interface'. Has it some deeper meaning or netcf can be enhanced? (and *libvirt* as well). Nikolay

The netcf API / libvirt Interface APIs are designed to work against the concept of logical network connections, which may comprise multiple physical interfaces. They are explicitly *not* a way to query all individual physical interfaces - that's what libvirt's node device APIs are for.

I donno. AFAIU you can start with bridge and unslaved physical interface. They are both in list and can be dumped. Then you enslave interface to the bridge via netcf's define and then physical interface can not be reached anymore. If I can not change host interfaces tree then it would be ok I guess. Nikolay

That is expected behaviour. You originally had 2 separate logical connections, and you've changed the system to have a single logical connection.
