If you have configured a virtual machine to use the host's CD or DVD drive or floppy disk drive, but this does not appear to work, make sure that the current user has permission to access the corresponding Linux device file. For example, for a CD or DVD drive this may be /dev/hdc, /dev/scd0, /dev/cdrom or similar. On most distributions, the user must be added to a corresponding group, usually called cdrom or cdrw or floppy.

On supported Linux distributions, uses udev to locate hardware such as CD/DVD drives and floppy disk drives.
