Xen users - Oct 2007 - DomU stops on boot inside Dom0 while booting

I have installed xen on a node and while starting up a guest while in
the kernel boot I am experiencing a hold/pause.  The kernel stops in the
boot sequence still loading the kernel at:

The only thing I can do in another terminal is to halt the process but I
am so out of ideas.  Any Ideas?

Each guest can be shutdown properly.  It seams like they both stop at
mounting the system.

It looks like perhaps they''re not outputting boot information to the
serial
console?  Perhaps this is what you''re seeing.

I see you have the message "Initializing xen vfb; pass xencons=tty to
prevent
this" appearing.  Could you try adding that to the kernel arguments and see
if that gets you any further?

Cheers,
Mark
