Ethernet device

Hi Matthias,

I am testing the iso image file on the qemu with the following line:
qemu -cdrom android.iso -boot d -m 1024 -net nic,model=e1000 -net user -serial stdio 


and the outcome of "lspci" is unfortunately terrible: 
"lspci: /sys/bus/pci/devices: No such file or directory"


Best Regards,

Are you using "real" hardware or are you using an emulator (e.g. qemu)? Does
"lspci" show something meaningful?
