No, sorry, I probably am not getting. Are you saying that, just booting
Xen and *not* doing anything else --either from SSH, from the keyboard
of that box, from serial connection... anything at all-- and without
any guest configured to auto start itself, results in these lines to
appear on your serial console?

Because this is what you just said above, and that's... well... just
impossible?!?! :-O

What's the output then, if you login (either via serial, ssh or regular
keyboad+monitor) and run `xl list' and `xl vcpu-list' as the very first
thing? ÂWhat's inside `ls -l /var/log/xen/' (or `ls -l
/var/local/log/xen')?

Well, it looks like the guest boot did not indeed go well, but that is
probably because of other thing... can you try uncommenting the line
'extra = "root=/dev/xvda1"' from the config?
