There are two types of vhostuser ports: dpdkvhostuser - OVS creates the socket and QEMU connects to it dpdkvhostuserclient - QEMU creates the socket and OVS connects to it But of course ovs-vsctl syntax for fetching ifname is different. So far, we've implemented the former. The lack of implementation for the latter means that we are not detecting the interface name and thus not reporting it in domain XML, or failing to get interface statistics.
