   If I understood you correctly, you want to bridge the interface 
without 802.1q, so the tag/untag would be done by the host machine?

   If that's the case you can bridge the guest's virtual interface to 
the vlan interface, so the guest won't see the tags.  You can't do with 
the VBox GUI, but the VBox TUI (VBoxManage ) is able to do what you 
want. Let's suppose you want to bridge the host's vlan10 interface with 
the first virtual interface of a virtual machine named "FreeBSD virtual 
machine" and let's suppose it will be a virtio interface:

      VBoxManage modifyvm "FreeBSD virtual machine" --nic1 bridge 
--nictype bridge virtio --bridgeadapter vlan10

   Actually I'm using this kind of setup with around 10 virtual 
machines, each one serving 5 vlans. It is a very flexible setup because 
the virtual machines don't need to worry about the physical segmentation 
of my network, but only the logical segmentation (at IP level).
