the vxlan part is definitely working, its the 'flat' part that i've just
added which is not.

and, more specifically, its the ability to attach a nova instance to it.
I'm not sure what i can do for screen shots, the error is the kind of
generic:

the 'unexpected vif_type' covers a wide variety of problems. I get this if
i add boot with a port-id on the new flat network, or if i boot with the
net-id of the new flat network.
