Converting a Hardware Virtualized Guest to a Paravirtualized Guest

Creating a Guest

Use the same MAC address as you use for the vif. If more than one MAC address 
is exported to the guest operating system, you must configure more network 
interfaces, for example, eth1, eth2. 

The NETMASK and BROADCAST address must match the corresponding 
network interface in dom0.

HWADDR is same as the MAC address in vif.

IPADDR is as in the /mnt/etc/hosts file.

DEVICE=eth0

BOOTPROTO=static

HWADDR=00:50:56:02:ff:d3

IPADDR=10.1.1.1

NETMASK=255.255.254.0

BROADCAST=10.1.1.255

ONBOOT=yes

TYPE=Ethernet

The /etc/fstab file does not require modification with a hardware virtualized 
guest. Hardware virtualized guests boot as a normal operating system. It reads the 
partition table as usual at boot time. 

Unmount /mnt.

#unmount /mnt

Create the guest.

#xm create -c /etc /xen/domain-config-file

Use VNCViewer to display the guest.

#vncviewer <hostname of dom0>

#password : welcome

The guest is displayed.

You may want to convert a hardware virtualized guest to a paravirtualized guest. This 
example uses Oracle Enterprise Linux 4 Update 4 as it does not support a direct 
installation as a paravirtualized guest. This procedure gives an example of installing 
Oracle Enterprise Linux as a hardware virtualized guest, then converting it to a 
paravirtualized guest.

To create an Oracle Enterprise Linux 4, Update 4, paravirtualized guest:

Copy the Oracle Enterprise-R4-U4-x86_64-dvd.iso image to the local file system of 
the Oracle VM Server computer

# ls -l /root/Enterprise-R4-U4-x86_64-dvd.iso 

-rw-r--r-- 1 root root 2530611200 Aug  2 13:03 /root/Enterprise-R4-U4-x86_

64-dvd.iso

Create a logical volume, which will be used as the guest disk image.

# lvcreate -L8G -n el4u4 VolGroup00

Run the virt-install command-line tool to create a hardware virtualized machine 
domU, and install the Oracle Enterprise Linux operating system.
