Never tried thing like this, but IMHO as long as your guest isn't
meant to be connected to "real world" ...meaning something like
brigdged to your real eth0, i think duplicate MAC is doable.

Oh ..and...maybe make sure your guests are on different VLANs....IIRC,
they are all hooked to VLAN 0 by default.
