I'm currently trying to get Xen working on an Pacifica system. But each time I 
try to start a fully virtualized guest domain, the system hangs just after 
the start with a black screen (paravirtualization works, btw).

I've also tried to monitor the system with the serial console, but I get 
nearly no useful info. If I don't specify the memory used by dom0 (with boot 
option "dom0_mem=xxx"), I can see the following error:

  Unable to open display.
  (XEN) domain_crash called from shadow_public.c:1564
  (XEN) Domain 1 reported crashed by domain 0 on cpu#0:

If I specify explicitely the amount of memory to be used by dom0, no error 
message appears, but the screen wents black, too. So I don't really know if 
to blame shadow_public.c and thus memory mapping respectively.

Have you ever been successful in running such a full virtualized guest domain 
on a Pacifica system, or do you have a clue or a secret tip how to manage to 
get this done?

Attached is the config file for the guest domain.
