Not, as far as I know. VDE works at level 2, and has no idea about IP addressing.

Actually, VDE does not even provide bridging support: that has to be provided by the operating system. VDE just builds a virtual switch, which can be attached to other VDE switches (local or remote) using “virtual plugs”. One of those plugs (vde_plug2tap) links the virtual switch to a TAP interface, and that interface has to be managed by the host operating system, either bridging it with real, physical interfaces, or doing IP forwarding.
