Appendix A. Using virsh to mount a CD-ROM image on an inactive domain

This appendix describes a process which allows users to mount CD-ROM images on inactive domains.

Procedure A.1. Mounting CD-ROM images with virsh on inactive domains

Create an XML configuration file for your guest, replacing guestname with your guest domains name and windowsguest.xml:
```
# virsh dumpxml guestname windowsguest.xml
```
Add the following entry under the devices tag in the XML configuration file (windowsguest.xml in this example). You must change the source file= parameter to the location of the drivers .iso file and adjust the dev= parameter if you already have a hdb entry.
```
<disk type='file' device='cdrom'>
  <driver name='file'/>
  <source file='/usr/share/xenpv-win-32bit/xenpv-win-32bit.iso'/>
  <target dev='hdb'/>
  <readonly/>
</disk>
```
Recreate the guest with the updated configuration file
```
# virsh define windowsguest.xml
```
The guest now has a CD-ROM device containing the para-virtualized drivers once rebooted.
Once the Windows guest has booted, open My Computer and you should see the Red Hat Para-virtualized drivers disk. Click on the disk to continue the installation.
