[Xen-devel] hypervisor console I/O

I think I'm on this list ...

Anyway, I have my plan 9 guest starting up, and I am into C code. I can 
call hypervisor exit and that works, so the obvious next thing is to call 
console i/o

So I call

HYPERVISOR_console_io(0, "HI!\n", 4);

but no good news from the xen console, I don't get anything at all. 

Anybody dealt with this one? Any debugging hints? If I fix xentrace_format 
(it's broken) will I see the calls from my guest to xen?
