Virtual machines (VMs) must remove unneeded serial devices.
An XCCDF Rule
Description
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.
