strance error when running Nova + Genode + Seoul (scenarion : seoul-auto.run)

[Parfait Tokponnon]

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,
