(In reply to Rodney W. Grimes from comment #6)

What you're saying is "what if I have 3 ethernet cards, with different
addresses all plugged into the same switch" ... in effect.  I suppose there's
nothing stopping the bridge interface from having the 3 aliases.  Thinking
about differences, you still have 3 IP addresses on the same MAC (in the vlan
case, not the three ethernet cards case).

If this is indeed the problem (I'm testing now) ... this needs some explicit
documentation somewhere.  This might be the second time I've come around to
this "documentation bug" ... but from a different direction.  The first time
was that the bridge straight up needed the IP not the vlan ... but without a VM
to think about.
