When you move a network, the important characteristic is the topology, not the communication path. That is, the *direction* the packets flow, not *how* they flow. For example, say you have a bunch of virtual CTC connections between VM TCP/IP and your VSE guests. They are in Subnet B. VM TCP/IP also connects to the external network on Subnet A. As long a VM TCP/IP remains as the routing "waypoint", you can change the VSE guests to a Guest LAN and not have any routing poblems. Now, if you begin to add or delete waypoints, then you will have routing changes. If you don't make those correctly, then you have problems. I couldn't tell from your pictures (they were somewhat mangled) what was "Before" and what was "After". Only by comparing those two can you tell if there are routing considerations.
