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.

For each virtual machine do the following:

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

Review the VMs hardware and verify no CD/DVD drives are connected.

or

From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the following command:

Get-VM | Get-CDDrive | Where {$_.extensiondata.connectable.connected -eq $true} | Select Parent,Name
