IIRC, the reason libvirt had been passing the ifname=XXX arg, is because Xenner wanted it know the name associated with the TAP device, and would then open it, rather than taking the FD passed in. Xenner long ago gained code todo the reverse fd -> name lookup though, so we should just kill this bogus code in libvirt now and drop ifname & script= args when passing an FD.
