Re: [Xen-devel] Xen at scale

[Ian Pratt <Ian.Pratt@xxxxxxxxxxxx>]

Dan,

I haven't had a chance to look at your patch, but you'll get
earlier console output if you hack kernel/printk.c to call
HYPERVISOR_console_io directly in the printk function, e.g.
add the following after "va_end(args);"  :

 HYPERVISOR_console_io(CONSOLEIO_write, sizeof(printk_buf), printk_buf );

That should at least indicate where abouts the failure is
happening. It might be easier to debug it as a domain other than
0 (non privileged) as it shouldn't be able to upset Xen.

Cheers,
Ian
