To resolve this issue, in the virtual machine settings, ensure that the Device Type of the CD/DVD drives is set to Client Device:
  1. Right-click the virtual machine and click Edit Setting.
  2. Set the Device Type to Client Device for the CD/DVD drive.

For more information on connecting DVDs to virtual machines, see the vSphere Virtual Machine Administration Guide.
