...identify a device on which you want to operate. There's no such way currently in use in libvirt so you need to come up with something to do it. The identifier is also desired for the metadata change event which would go with the APIs. It might be possible to do this even without APIs but the usefulnes would be rather limited as it was with the domain metadata.

Hi, Currently libvirt supports metadata in the domain XML. This is very convenient for data related to the VM, but it is a little awkward for devices. Let's pretend I want to have extradata (say, a specific port for a virtual switch) related to a device (say, a NIC). Nowadays I can store that data in the metadata section, but I need some kind of mapping to correlate this piece of information
