So the serial port settings do not match in the servers..

Change the xen-3.5-gz line in grub.conf to have "com1=9600,8n1", maybe
that's a better default..

Or then don't use "cat /dev/ttyS0", but use "minicom" instead.. and
configure the speed etc there (I think it's O or P to go to configuration).

You need to have same speed/settings on both servers for the serial
console logging to work OK.

I don't think locales have anything to do with this problem..
