installation CD-ROM, to the guest:

# cd extra_kernels/EL4U5PV_64/

# scp kernel-xenU-

version

.EL.x86_64.rpm 10.1.1.1:

Log in to the guest as root and replace the contents of the /etc/modprobe.conf file
with:

alias scsi_hostadapter xenblk

alias eth0 xennet

Install the kernel-xenU RPM:

# rpm -ivh kernel-xenU-

version

.EL.x86_64.rpm

Shut down the guest. Modify the host configuration file /etc/xen/el4u5 to an
entry similar to:

name = "el4u5"

memory = "512"

disk = [ 'phy:/dev/VolGroup00/el4u5,hda,w', ]

bootloader="/usr/bin/pygrub"

vcpus=1

on_reboot = 'restart'

on_crash = 'restart'

memory = "512"

disk = [ 'phy:/dev/VolGroup00/el4u5,hda,w', ]

vif = [ 'bridge=xenbr0', ]

bootloader="/usr/bin/pygrub"
