[Xen-users] How to show deug info via XENPRINTF?

["Yuan, Jue" <yuanjue122@xxxxxxxxx>]

Hi all.

I am trying to debug a kernel that I built, and I hope I could see some debug
info printing out via XENPRINTF. I use it in the source code of kernel like:

XENPRINTF("nr_pages: %ld shared_info: 0x%lx flags: 0x%lx pt_base: 0x%lx "
                 "mod_start: 0x%lx mod_len: 0x%lx\n",
                 xen_start_info->nr_pages, xen_start_info->shared_info,
                 xen_start_info->flags, xen_start_info->pt_base,
                 xen_start_info->mod_start, xen_start_info->mod_len);

But it doesn't print anything out when start this kernel as domU. I think I
must miss something here.

Any ideas about how to do it? Thanks in advance :-)

PS: I am using xen-3.0.2-2
