Yes.  I did try bridge first but I may not have understand all the nuances. 
  I also thought that "switch" meant the same thing as a physical switch but 
I guess it is more like a router.  That was the point of my subject.

"ifconfig bridge0 addm bge0" in my case but I also have a private network so 
"ifconfig bridge0 addm bge0 addm bge1" then.  Or do I need two bridges?

This is the part I am trying to automate so that VM can freely move between 
hosts.  Is there a way to make tap automatically add itself to a bridge?

Thanks for your help.
