That worked! My Smart UPS 1400 is now being monitored/controlled from dom0 with apcupsd. There were some errors in /var/log/messages, though: Jul 9 12:50:45 xenmaster kernel: serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A Jul 9 12:50:45 xenmaster kernel: 00:06: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A Jul 9 12:55:02 xenmaster kernel: Kernel command line: ro root=/dev/vg00/root xencons=tty1 Jul 9 12:55:11 xenmaster kernel: WARNING: Failed to register Xen virtual console driver as 'tty1' Jul 9 12:55:14 xenmaster kernel: serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A Jul 9 12:55:14 xenmaster kernel: 00:06: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A I'll try with a different tty later, say tty6. But, I don't know if that will fix the above warning. I have another question: can I hand the serial port to a domU, or does it have to be present in dom0?
