Installation guide

<disk type='file' device='disk'>
<driver name='file'/>
<source file='/dev/hda6'/>
<target dev='hda'/>
</disk>
Modify each disk entry, as desired, to use the para-virtualized by changing the driver
elements as shown below.
<disk type='file' device='disk'>
<driver name='tap' type='aio'/>
<source file='/dev/hda6'/>
<target dev='xvda'/>
</disk>
10. Add any additional storage entities you want to use for the para-virtualized block device
driver.
11. Restart your guest:
# xm start YourGuestName
Where YourGuestName is the name of the configuration file or the guest operating system's
name as defined in its configuration file in the name = "o s_n ame" parameter.
12. Reconfigure the guest network.
12.3.2. Inst allat ion and Configurat ion of Para-virt ualiz ed Drivers on Red Hat
Ent erprise Linux 3
This section contains detailed instructions for the para-virtualized drivers in a Red Hat Enterprise 3
guest operating system.
Note
These packages do not support booting from a para-virtualized disk. Booting the guest
operating system kernel still requires the use of the emulated IDE driver, while any other (non-
system) user-space applications and data can use the para-virtualized block device drivers.
Driver In st allat io n
The list below covers the steps to install a Red Hat Enterprise Linux 3 guest with para-virtualized
drivers.
1. Install the latest kernel version. The para-virtualized drivers require at least Red Hat
Enterprise Linux 3.9 kernel version kernel-2.4.21-60.EL for all the required headers.
2. Copy the kmod-xenpv rpm for your hardware architecture and kernel variant to your guest
operating system.
3. Use the rpm utility to install the RPM packages. Ensure you have correctly identified which
package you need for your guest operating system variant and architecture.
