Hello to all,
I'm trying to run l4linux on fiasco_x86_32 on QEMU. But i'm not getting anything on QEMU except 2 penguins... and i'm getting a console messages as......

can u please give me the solution........
*Thanks,* Raja Sekhar
Hi Raja,
to me it seems you've hit a recent bug, have a look at issue #744:
https://github.com/genodelabs/genode/issues/744
On Genode's current master branch, that issue is already fixed. Could you please update your repository, and give it a try?
Regards Stefan

It's because the L4Linux-stub driver waits for the announcement of a Nic session, which does not happen (see: ports-foc/src/lib/l4lx/genode_net.cc). The 'Nic::Connection' does not timeout or throw an error, as of now, it simply waits.

Hi,
just for completeness:
my mail was a bit overhasty. Raja obviously works on top of x86, where the USB driver normally isn't used as NIC driver. Therefore, my analysis was wrong. Nevertheless, I can see from the log output, that he/she (sorry for my lack of knowledge) uses an older version of Genode. Nowadays, the L4Linux run script uses the KDB serial driver, and all logging outout, as well as the Linux kernel console gets printed to the same serial line. That output would be helpful, to see what NIC driver is used, or what gets wrong on behalf of the drivers. Alternatively a look into the "kdb.log" file would help.

Init will throw an "Unavailable" exception to its children, when they ask for a service, for which no route is existent. In that case the NIC driver in L4Linux would exit its probing routine, and everything is fine. But if there is a NIC driver, and init's configuration claims it provides the service "NIC", then the thread in init, that serves the parent interface for the L4Linux task, will block until the service "NIC" becomes available, as soon as L4Linux tries to open that session. The result is, what I've observed in issue 744. If you state a service will be provided, but it doesn't get announced, your dependent clients will block forever.
