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
