Hi Alexander, That's correct, when I had set the timeout to 600, it ran perfectly. Concerning the layers of virtualization, I understand well your concerns. It was just for trying purpose. Really, I am already considering moving to a real development platform and let the Linux VM. Regards,

developing within a VM is no issue, but actually running the result from within a VM is adventurous - at least - most the time, based on practical experience.
In your case you have 3 level of virtualization/emulation nested - you are running Ubuntu in Virtualbox (1), then you run Genode/Nova inside Qemu (2) ontop of (1) and finally you run a Linux VM with Seoul VMM (3) on top of (2).
Beside the obviously waste of CPU time and increasing your idle time, you have to rely on all upper levels to work correctly. Such a assumption and in principal such a development setup just leads to various types of frustrations - I would try to avoid that.
And Yes, when I had invoked qemu directly with the provided command in
the
log file it worked too. So what could be the explanation?
Our run tool sets for automatically tested scripts (as seoul-auto.run) a timeout until it must have been finished. Since you say it works for you when you are calling qemu directly - it could be that the execution time in your 3-level nested virtualization setup is too short.
You may try to increase the timeout in seoul-auto.run (search for run_genode_until) or try using seoul-net.run instead, which is mainly the same setup but without timeout.
Does this change things for you ?
If not, you would have to find out why tcl/expect stops working with a eof (in <genode-dir>/tool/run/run) error when waiting for qemu output.

Alex.
