Don't worry about the messages about "Could not open file...". Those are
not errors but merely status reports. The mentioned files are optional
and not needed for the demo scenario.

The log output looks good to me. There is no unexpected message at all.

Maybe your problem is related to Qemu or libSDL? Does the Qemu window
pop up at all? You can find the Qemu command line in the log output
above the Genode boot messages. What happens when you invoke it manually
using these arguments? Just as a test, you could also try starting a
Linux Live CD in Qemu to check that everything is fine with the graphics
output of Qemu.

Btw, are you using base-fiasco (the L4/Fiasco kernel) or base-foc (the
Fiasco.OC kernel)? I cannot gather that information from the snippet of
the log output.

Norman
