Xen community - 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.
