VDE is a virtual network that can be spawned over a set of physical
computers over the Internet.
VDE connects together: (1) real GNU-linux boxes (tuntap) (2) virtual
machines: UML-User Mode Linux, qemu, bochs, MPS.
VDE can be used:
- to create a general purpose tunnel (every protocol that runs on
Ethernet can be put into the tunnel)
- to connect a set of virtual machine to the Internet with no need of
free access of tuntap
- to support mobility: a VDE can stay interconnected despite of the
change of virtual cables, i.e. the change of IP addresses and
interface in the real world
