5.1.2 Virtual CD Readers on Fully Virtual
Machines
A fully virtual machine can have up to four block devices comprised of virtual CD
readers and virtual disks. A virtual CD reader on a fully virtual machine interacts with
the inserted CD in the way you expect a physical CD reader to interact. For example,
in a Windows* XP* virtual machine, the inserted CD appears in the Devices with
Removable Storage section of My Computer.
When a CD is inserted in the physical CD reader on the host computer, all virtual ma-
chines with virtual CD readers based on the physical CD reader, such as /dev/cdrom/,
are able to read the inserted CD. Assuming the operating system has automount func-
tionality, the CD should automatically appear in the file system. Virtual CD readers
cannot be used to write data to a CD. They are configured as read-only devices.
5.1.3 Adding Virtual CD Readers
Virtual CD readers can be based on a CD inserted into the CD reader or on an ISO
image file.
1 Make sure that the virtual machine is running and the operating system has
finished booting.
2 Insert the desired CD into the physical CD reader or copy the desired ISO
image to a location available to the virtual machine's file system.
3 Run Virtual Machine Manager.
4 Select the virtual machine, then click Details.
