You can find this name by retrieving the XML for the active domain, and looking for <target dev='xxx'/> in each <interface> element - the 'xxx' is the tap interface name, and should be put in the path arg when calling virDomainInterfaceStats().

I would query for stats: virDomainInterfaceStats(dom, "vnet0", ...); virDomainInterfaceStats(dom, "macvtap0", ...); Michal
