You've configured Xen hypervisor (xen.gz) to use the serial port as a console,
do you get XEN output on the serial? If not, the settings are wrong.
For dom0 linux kernel you've specified to use the hypervisor (hvc0) as a
console.
So dom0 linux kernel messages should go to the serial through Xen.

Not sure if you can use ttyS0 from dom0 since Xen is already using it..

So dom0 starts fine. Just settings are wrong.
