CitectSCADA Virtualized Environment

As others have stated, USBAnywhere seems to work well if you've got hardware dongles.

WRT soft licensing issues, licenses tend to be based on a combination of the hard drive device ID, network cards and their MAC addresses, computer ID etc. In a hardware setting this stuff doesn't change. Most likely of these to change in a virtual setting is the MAC address if it hasn't been set to static. This is a great proactive step you can take in specification stage: STATIC MAC ADDRESSES.

Hyper-V in particular does MAC addressing poorly (IMO). All servers start with the same default virtual dynamic MAC range, and you need to go and change them so they don't clash. Out of ignorance I hadn't done this and the result was something called "MAC Flap" on the switch, where the MAC will be registered to one physical port, then switch to another one and back to the first in perpetuity.
