For the greater community,
If an organization has purchased McAfee DLP components they are entitled to run as many virtual instances of the DLP appliance modes as they wish.
For Exampe: DLP Manager / DLP Monitor / DLP Discover / DLP Prevent:
If your license is for these components you can deploy as many as you wish, you just have to accomodate for node counts for these.
Also per McAfee rep: not recommended to run DLP Manager as a VM.
