Last time I promised, that I’ll write how to connect to VM via serial console. So – this time very shortly and without any explanations:

On the guest OS:

echo ttyS0 >> /etc/securetty

Now add following param to kernel params in /etc/grub.conf:

console=ttyS0

And the last thing:

echo "S0:12345:respawn:/sbin/agetty ttyS0 115200" >> /etc/inittab && init q

Now restart the guest OS, and You’re good to connect to VM via:

virsh console guest_id

If You feel like interested in what happened above – please ask questions in comments – I’ll explain :)
