How do i configure a serial console for a f10/x86_64/PV guest to work.
title Fedora (
        root (hd0,0)
kernel /vmlinuz- ro root=/dev/rootvg/root_lv rhgb quiet console=ttyS0
        initrd /initrd-

Under my domU using RHEL, there are several steps:

1. In /boot/grub/grub.conf the kernel line has console=tty0 console=xvc0, i.e.
kernel /boot/vmlinuz ...  console=tty0 console=xvc0

When multiple consoles are specified, all get kernel messages but only the last one gets /dev/console messages, IIRC.

2. To allow login to the virtual serial console, /etc/inittab has
co:2345:respawn:/sbin/agetty xcv0 9600 vt100-nav

3. add xvc0 to /etc/securetty
