For fully-virtualized guests, make sure the guest definition contains:
<serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target port='0'/>
</console>
If you add this, you'll need to redefine the guest, then shut it down
completely ("poweroff" the guest, not reboot).
# virsh define /etc/libvirt/qemu/guest.xml
Once a serial console is defined in the guest, set up grub. Edit
/boot/grub/grub.conf and replace the timeout, splashimage, and
hiddenmenu lines with:
timeout=5
serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=5 serial console
Make sure all of the "kernel" lines contain a serial console arg:
kernel /boot/vmlinuz-... ro root=LABEL=/ console=ttyS0,115200
And finally make sure that /etc/inittab starts a getty on the serial
console:
s0:2345:respawn:/sbin/agetty -L 115200 ttyS0 vt100
The last three are the same steps you'd take to set up a machine with a
physical serial console.
