Hello Naveen,
the l4linux.run script is used as an automated test, just to see whether
l4linux boots through, and is able to do a HTTP request resp. whether
network is working. The automation is done via the run-script (TCL/TK
language) itself. It uses 'expect' to control the Linux terminal (a
serial console), which is redirected to the terminal you used to start
the run-script (see the second '-serial' argument when qemu is
executed). Moreover, you cannot see the typical qemu window
(representing the framebuffer) because qemu is called with the
'-nographic' argument.
As the output you've posted shows the test has succeeded. You can see
how the whole build process went fine, after that the initramfs image
(used as userland playground for Linux) is downloaded, an ISO image gets
created, and after that how qemu starts the image. The whole Linux
serial console is redirected to the same terminal you used to start the
script, that's why you can see all the kernel messages until the
run-script detects that the test succeeded. At that point it will stop qemu.
If you want to do something with the Linux instance interactively, you
might start the same image via qemu without using the run-script itself.
The correct qemu command line is already shown in your output listing.
or even better, you start to investigate how the l4linux.run script
works, and what the several qemu argument are doing in general.
BTW a very similar question was already raised in our issue tracker,
maybe reading that discussion will help you to get a better understanding:
https://github.com/genodelabs/genode/issues/180#issuecomment-5215453
But, the mailing-list is a much better place to ask these kind of
questions, so thank you for asking it here, and not in the issue tracker
;-). Nevertheless, it's hard to re-find discussions we had without a
meaningful subject, and even with a lot of different subjects in one
long discussion-thread. So next time you've a new question, that is
unrelated to the previous discussion, would you please start a new
thread with a more meaningful subject (e.g. for this mail "L4Linux on
Fiasco.OC: no terminal" would have been fine).
Best regards
Stefan
