I'll be using terminology as defined here:

What I meant is to have macvtaps for your L0 guest, which are then
visible as regular interfaces in in. These interfaces could be then
passed thru to your L1 guest. There's no need for SRI-OV, no need for
bleeding edge HW, nothing. It's all done in software.
