I need to verify, but the problem seem that efi rom are a lot biffer than pxe. (190k vs 60k)

efi rom -> new efi rom migration should work, if the size don't change. (seem to be the case looking at qemu git history)

What are the correct property names for the other devices types? 

rtl8139, pcnet-pci, ne2000, e1000?
