No NIC:
-net none
=> No iPXE ROM (correct).

but with the previously listed config no iPXE ROM should be there. Saw 
this is done through paravirtualization from Seabios/QEMU or KVM. So there
must be a bug with the empty romfile options with net or device (I guess) 
in QEMU/KVM.

The vapic.bin is ok.

BTW: Will you integrate the boot one liner?

Ciao,
Gerhard
