Information

Virtual machines (VMs) must remove unneeded serial devices.

GROUP ID: V-258725RULE ID: SV-258725r959010

Ensure no device is connected to a virtual machine if it is not required. For example, floppy, serial, and parallel ports are rarely used for virtual machines in a data center environment, and CD/DVD drives are usually connected only temporarily during software installation.

Solution

The VM must be powered off to remove a serial device.

For each virtual machine do the following:

From the vSphere Client, right-click the Virtual Machine and go to "Edit Settings".

Select the serial device, click the circled "X" to remove it, and click "OK".
