Add CD-ROM workflow - Need List of Device Types

Hi All,

        Can anyone share a list of Device Types which can be used in Add CD-ROM workflow. I want to select "Datastore ISO file", but workflow execution fails with error message "Unsupported CD-ROM device type (Datastore ISO file) (Workflow:Add CD-ROM / Add CD-ROM (item7)#35)". i tried with different combinations like "Datastore iso", "cdrom-raw", etc.,

Note: DeviceType input accepts String.

Objective: I want to create VM with CD-ROM, attach OS ISO file & install Guest OS. If anyone already has this kind of workflow & can share,  then it would be helpful for me.

Thanks in Advance.
