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,

Hi Matthias, thanks for the fast reply. Indeed I have already added the bus for PCI devices into the x86.vbus file as follows:
I guess the "pci[] => wrap(hw-root.match("PCI/CC_02"));" line should have been handling this, I checked also the l4 kernel and saw that the PCI device support was already chosen, still I can not achieve eth device on the virtualized android kernel
Are you using "real" hardware or are you using an emulator (e.g. qemu)? Does "lspci" show something meaningful?
Matthias.
Best Regards

Dear all,
I have been working on running different linux based OSs on top of L4. Is there any documentation or tutorial where I might find information on how to make platform devices available for the linux OS running on top of L4. For instance, I could not get ethernet devices detected by the OS.
In case of a PCI device you simply add that to the respective vbus and compile the corresponding driver into L4Linux. Make sure to activate the virtual PCI bus driver in L4Linux.
Matthias.
