In fact I'm not sure about the policy.
Since xenLinux/x86 defines CONFIG_XEN_DISABLE_SERIAL=y, I thought
it was the xen's policy. However I'm not sure whether it's right.
It seemed that you used serial port from dom0, I wanted to confirm it.

It is bad that xen and dom0 accesse to the same UART.
This is only what I'm sure about.
