Well, it is. vlan=x really means "the ethernet segment named x". If
you connect all your guest nics to one vlan, you are connecting them all
to one ethernet segment, so any packet transmitted on one will be
reflected on others.
Whether this is a useful feature is another matter, but the code is
functioning as expected.
