NOTE
Only limited support for virtual machine removable media is available in the
original version of SUSE Linux Enterprise Server. Much of the following infor-
mation pertains to functionality available in maintenance updates.
If you are installing drivers from the SUSE Linux Enterprise Virtual Machine
Driver Pack, proceed by completing one of the following:
• If you have updated to Virtual Machine Manager 0.3.1-0.24 or later, com-
plete the instructions in Section 5.1.3, “Adding Virtual CD Readers”
(page 35) to set up the ISO image file as a virtual CD reader.
The most recent Virtual Machine Manager package is available through the
SUSE Linux Enterprise 10 SP1 update channel.
• If you are running an earlier version of Virtual Machine Manager, you must
set up the ISO image file as a virtual CD reader when you create the virtual
machine, or add a virtual CD reader based on the ISO image file following
the instructions in
Section 5.1.4, “Adding Virtual CD Readers (Command
Line Method)” (page 37).
5.1.1 Virtual CD Readers on Paravirtual
Machines
A paravirtual machine can have up to 16 block devices comprised of virtual CD readers
and virtual disks. On paravirtual machines, virtual CD readers present the CD as a vir-
tual disk with read-only access. Unless you remove the virtual CD reader, the virtual
machine assumes that the originally-inserted CD is still in the CD reader, even if you
have ejected it. If it has been ejected, the virtual machine will not be able to access the
CD (or any other newly-inserted CD) and will receive I/O errors. Virtual CD readers
cannot be used to write data to a CD. They are configured as read-only devices.
After you have finished accessing a CD on a paravirtual machine, it is recommended
that you remove the virtual CD reader from the virtual machine.
If several CDs are needed for the installation of an operating system, make all of them
available to the paravirtual machine and change the path to the data on request. If you
