1. Hardware Virtualised (HVM)

1.1 Boot the guest virtual machine.

1.2 Modify the /boot/grub/grub.conf file - append 'console=ttyS0,9600n8' to the kernel line of the default boot title e.g.:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,0)
#          kernel /boot/vmlinuz-version ro root=/dev/hda1
#          initrd /boot/initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title Enterprise Linux Enterprise Linux AS (2.6.9-78.0.8.2.1.EL)
        root (hd0,0)
        kernel /boot/vmlinuz-2.6.9-78.0.8.2.1.EL ro root=LABEL=/ console=ttyS0,9600n8
        initrd /boot/initrd-2.6.9-78.0.8.2.1.EL.img

(For EL6) Please create a file "/etc/init/serial-ttyS0.conf" with following content:
# cat /etc/init/serial-ttyS0.conf

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [016]

instance ttyS0
respawn
pre-start exec /sbin/securetty ttyS0
exec /sbin/agetty /dev/ttyS0 9600 vt100-nav

1.4 Modify the /etc/securetty file - add an entry for the ttyS0 device e.g.:
console
ttyS0
vc/1
vc/2
vc/3
