Xen users - Sep 2008 - Where can I see message printed by do_console_io?

Hi, all

I''m learning Xen with the help of the book The Definitive Guide to Xen
Hypervisor.
In Chapter 2 there''s an example which outputs ''Hello
World'' to the emergency
console, the code snippet looks like
HYPERVISOR_console_io (CONSOLEIO_write , 12 ,"Hello World\n" ) ;

static inline int HYPERVISOR_console_io(int cmd, int count, char *str)
{
    return _hypercall3(int, console_io, cmd, count, str);
}

while _hypercall3 is a macro calling corresponding function in the hypercall
page, in this example it will just call

do_console_io(CONSOLEIO_write, 12, "Hello World\n")'';

but when i run xm create domain_config, i find message "Hello World"
nowhere.
Where can i see this message?

Many thanks for your reply.

oops...
I''m totally sorry - I saw this mail first coming up on the
xen-community list(where from time to time such technical questions
come up because it seems not to be clear enough decsribed on the list
subscription pages), but replied to the second post that actually
already appeared on the right list :(
