Red Hat Enterprise Linux users may use the dd (data duplicator) utility to make images from the supported
Virtual Floppy media types (and vice-versa)
dd if=<input-file> of=<output-file>
where input-file is the input file or device, for example, /dev/fd0
where output-file is the output file or device, for example myimage.bin
What does Virtual Media look like at the
server?
On Windows systems, you see additional CD and removable media drives appear in "My Computer." On Red
Hat Enterprise Linux systems, you see devices that can be mounted. You can find the device names by looking
at /etc/fstab.
How do I know which drives are my virtual
media drives?
When you connect your management station drive to the managed system drive then the title of the inserted
media should automatically appear next to the drive letter on Windows systems. But the best way to know
which drive is the virtual media drive and which is the physical drive is by opening/mounting the drive and
looking at its content.
Will the drive letters change on Windows
systems?
Generally, the drive letters will not change. So if you have a CD drive that is labeled D: and a removable media
drive that is labeled F:, then those drive letters will remain the same.
How do I find my device names on Red Hat
Enterprise Linux systems so I can mount
them?
You can look at the /etc/fstab file which lists the device names for all your devices. When you know the
device name, then you can use the mount and umount command to mount and unmount your CD or floppy
drives.
To manually identify the virtual media devices, type the following command:
cat /var/log/messages | grep VIRTUAL
Then look for mount points for those devices in the /etc/fstab file, for example:
cat /etc/fstab | grep /dev/hde
Finally, use the associated mount point on the mount command, for example:
mount /mnt/cdrom1
What do I need to install on the client side
for the Virtual Media feature to work?
For a Windows management station, you must install an ActiveX web plug-in. For a Red Hat Enterprise Linux
management station, you must install a Mozilla plug-in. The plug-in is installed automatically when you access
the Virtual Media page for the first time or when a newer version of the plug-in is available.
Do I need to install this plug-in every time I
use the Virtual Media feature?
No. You only need to install the plug-in once when the feature is used for the first time unless a newer version
becomes available.
Will I need to have administrator rights in
Windows to install the ActiveX plug-in.
You must have administrator privileges on Windows systems to install and use the Virtual Media feature.
What privileges do I need to install and use
the Virtual Media plug-in on a Red Hat
Enterprise Linux management station?
You must have write privileges on the browser's directory tree in order to successfully install the Virtual Media
plug-in.

Can I use my virtual drives under any
version of NetWare?
Currently, the Virtual Media feature is not supported under any version of the NetWare operating system.
NetWare drivers ignore the virtual drives and do not make them available to the system.
