Yes and no. There are two modes right now in which domifaddr can
operate. The first one is asking guest agent (*) the second one is
asking dnsmasq (well, consulting a database that is updated on each dhcp
transaction, but no need to get too technical in here).
* - the problem with guest agent is that guest can rename it's
interfaces as it likes. Not only that, it can create other interface
structure as seen from the outside, e.g. join two devices into a
bonding, or create a virtual interface over "physical" one. Therefore it
can be hard to find matching between an interface as seen from the guest
and interface as seen from the host.
