CD-ROM Drive Does Not Work in Virtual Machine (1547)

Details

The CD-ROM drive in my virtual machine does not always work. For example, it cannot play music CDs. Why is this happening?

Solution

This issue occurs on Linux hosts only. Under certain circumstances, data from the CD-ROM is not detected by GSX Server and the CD-ROM drive does not function. One cause of this issue is that the configuration of the physical CD-ROM drive on the host may be modified to use a relative symlink to the device.

To correct this issue, first check to see if the CD-ROM drive is set up as a relative symlink. In a terminal, run the following command:

ls -lo /dev/cdrom

If the terminal returns output like the following, you have a relative symlink which must be fixed:

  lrwxrwxrwx    1 root      3 2005-06-21 12:18 /dev/cdrom -> hdc

To fix the relative symlink, follow the steps below.

If the section of the output after -> starts with a / or if /dev/cdrom is not a symlink at all (that is, the line in the output does not start with l), then the workaround in this article does not apply. If the CD-ROM drive is not configured as a symlink but you are having issues with the CD-ROM drive in a virtual machine, file a support request at www.vmware.com/requestsupport.

If the CD-ROM drive is configured as a symlink, replace the relative symlink with an absolute link. Complete the following steps.

  1. On the GSX Server Linux host, log on as root.
    su -

  2. In a terminal, run the following command. This example assumes the CD-ROM drive is linked to the default CD-ROM device, typically hdc0.
    ln -sf /dev/hdc0 /dev/cdrom
