Thank you for your reply.

The error seems to come from the "/arch/powerpc/kernel/prom.c" file at line 650.

I can guess that the version of the dtb used for the guest is too old. So which 
dtb should I use?
I tried using the mpc8544ds.dtb compiled from a 4.x mainline linux but I get 
the same error.

And also, shouldn't I be able to see this error on the console? Why it doesn't 
get printed there?
