Oracle Audio Technologies E10898-02 manual Restart the guest, using the xm command-line tool

Converting a Hardware Virtualized Guest to a Paravirtualized Guest

9.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

10.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'

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

# xm create -c el4u4

The hardware configuration is displayed.

12.Remove the configuration for the network adapter and keyboard.

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

14.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'

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

# ifconfig eth0

Take note of the HWaddr (MAC address).

16.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.

17.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', ]
