Virtual media session settings

You can determine the behavior of the appliance during a virtual media session using the
options provided in the on-board web interface Appliance Virtual Media Session Settings
screen. Virtual media session settings include session lock, access mode and encryption level.
Table 4.4 describes the virtual media session settings.

To configure virtual media in the on-board web interface:
1. Click Appliance - Appliance Settings - Sessions - Virtual Media Settings.
Description
The locking option specifies whether a virtual media session is locked to the KVM session on the
target device. When locking is enabled (default) and the KVM session is closed, the virtual media
session will also be closed. When locking is disabled and the KVM session is closed, the virtual
media session will remain active.
You may set the access mode for mapped drives to read-only or read-write. When the access
mode is read-only, the user will not be able to write data to the mapped drive on the client
server. When the access mode is read-write, the user will be able to read and write data from/to
the mapped drive. If the mapped drive is read-only by design (for example, certain CD/DVD
drives or ISO images), the configured read-write access mode will be ignored. Setting the read-
only mode can be helpful when a read-write drive such as a mass storage device or a USB
removable media is mapped, and you wish to prevent the user from writing data to it.
You may configure zero to four encryption levels for virtual media sessions. Any combination is
valid. The choices are: DES, 3DES, 128-bit SSL and AES. The default is no encryption (no
encryption levels selected).
