OK.  Now I think I finally understand what you really want.  This should do it:

ovs-vsctl add-br xenbr2
ovs-vsctl add-port xenbr2 eth2
ovs-vsctl add-port xenbr2.100 xenbr2 100
ovs-vsctl add-port xenbr2.200 xenbr2 200

(It is not strictly necessary to make xenbr2.100 and xenbr2.200 "fake
bridges" as above, but it is the most convenient way given the
ovs-vsctl commands.)
