Enable login via the console. The default console device in a XenServer system is xvc0. Ensure
that etc/inittab and etc/securetty have the following lines respectively:

# grep xvc0 etc/securetty 

xvc0

Ensure the ramdisk supports PV disk and PV network. Customize this for the kernel version you
have determined above.

# chroot /mnt/loop/centos54

# cd /boot/

# mv initrd-2.6.18-164.15.1.el5xen.img initrd-2.6.18-164.15.1.el5xen.img.bak

# mkinitrd -f /boot/initrd-2.6.18-164.15.1.el5xen.img --with=xennet --preload=xenblk --

omit-scsi-modules 2.6.18-164.15.1.el5xen
