Code compiles, when when using "VBoxManage" but it's help does not
show me "vde" option.

TAP interface existed in VirtualBox 2.0 (and was dropped in 2.1, in
favor of "vboxnetflt" module). "FlexiNetwork" appeared in VirtualBox

1. Start VM
2. VM Menu->Devices->Network Adapters
3. Try to change attachment of VDE network to another VDE switch or
to non-VDE network (when VM is running, on the fly)

Actual results:
VDE is not disconnected from VDE switch 1, and is not connected to VDE switch 2.

Expected results:
Running VM should be able to plug/unplug to different VDE switches,
and other non-VDE networks on-the-fly, without reboot.
