serial port

How do I enable console redirection under OpenBSD so that I can see my remote server boot information and any diagnostic information that is normally printed to the screen? I’ve already enabled serial ports in my server BIOS and wired them up. How do I configure and access OpenBSD UNIX x86/amd64 server over serial console?

I‘m using KVM to run multiple virtual machines under Redhat Enterprise Linux server 5.5. I’ve installed FreeBSD 7.x 64 bit as guest operating systems. How do I redirect the FreeBSD version 6, 7 or 8 virtual machine console to a serial port using virsh console command for management purpose from host itself?
