Out of curiousity, what is the use-case for this?

The short answer is you can't do this.

I went through this some time ago, except my use-case was a firewall 
routing for multiple VLANs, with all the VLANs on a single interface. 
This is a common scenario in our current VMware deployments.

VM (guest) interfaces cannot handle VLAN routing.  It has to do 
something with in order to that, the whole network layer needs to be 
opened up tot he VM needing the access, and that poses a security risk. 
  My explanation is probably a bit wrong, but there was a good 
discussion about it on my thread:

<http://lists.ovirt.org/pipermail/users/2014-January/thread.html#20101>

My thread is the one that is "[Users] Networking questions (LONG)"

I am currently looking into using the Neutron appliance, since it uses 
openVswitch, and may be able to do what we were originally looking to do 
(though we have run into a bit of a roadblock with that at the moment as 
far as getting the Neutron appliance working on our lab host)
