Converting a Hardware Virtualized Guest to a Paravirtualized Guest

Creating a Guest

Edit the /boot/grub/grub.conf file in the guest and change the default to point to 
this entry:

title Enterprise Linux Enterprise Linux AS (2.6.9-42.32.0.0.1.ELxenU)

        root (hd0,0)

        kernel /boot/vmlinuz-2.6.9-42.32.0.0.1.ELxenU ro root=LABEL=/

        initrd /boot/initrd-2.6.9-42.32.0.0.1.ELxenU.img

Shut down the guest. Modify the host configuration file /etc/xen/el4u4 to an 
entry similar to:

name = "el4u4"

memory = "512"

disk = [ 'phy:/dev/VolGroup00/el4u4,hda,w', ]

bootloader="/usr/bin/pygrub"

vcpus=1

on_reboot   = 'restart'

on_crash    = 'restart'

Restart the guest, using the xm command-line tool:

# xm create -c el4u4

The hardware configuration is displayed.

Remove the configuration for the network adapter and keyboard.

Log in to the guest, and delete the /etc/sysconfig/hwconf file.

Shut down the guest.

Modify the guest configuration file /etc/xen/el4u4 to add a vif entry similar to:

name = "el4u4"

memory = "512"

disk = [ 'phy:/dev/VolGroup00/el4u4,hda,w', ]

vif = [ 'bridge=xenbr0', ]

bootloader="/usr/bin/pygrub"

vcpus=1

on_reboot   = 'restart'

on_crash    = 'restart'

Start the guest and log in as root. Run the command:

# ifconfig eth0

Take note of the HWaddr (MAC address). 

Replace the contents of the /etc/sysconfig/network-scripts/ifcfg-eth0 file with:

TYPE=Ethernet

DEVICE=eth0

BOOTPROTO=dhcp

ONBOOT=yes

HWADDR=xx:xx:xx:xx:xx:xx

Replace xx:xx:xx:xx:xx:xx with the actual MAC address reported by the ifconfig 
command in the guest.

On the host, edit the domU configuration file /etc/xen/el4u4, and add the MAC 
address to the vif entry:

vif = [ 'mac=xx:xx:xx:xx:xx:xx, bridge=xenbr0', ]
