BESS transport does not require any special privileges.
VDE vector transport
--------------------
Virtual Distributed Ethernet (VDE) is a project whose main goal is to provide a
highly flexible support for virtual networking.
http://wiki.virtualsquare.org/#/tutorials/vdebasics
Common usages of VDE include fast prototyping and teaching.
Examples:
``vecX:transport=vde,vnl=tap://tap0``
use tap0
``vecX:transport=vde,vnl=slirp://``
use slirp
``vec0:transport=vde,vnl=vde:///tmp/switch``
connect to a vde switch
``vecX:transport=\"vde,vnl=cmd://ssh remote.host //tmp/sshlirp\"``
connect to a remote slirp (instant VPN: convert ssh to VPN, it uses sshlirp)
https://github.com/virtualsquare/sshlirp
``vec0:transport=vde,vnl=vxvde://234.0.0.1``
connect to a local area cloud (all the UML nodes using the same
multicast address running on hosts in the same multicast domain (LAN)
will be automagically connected together to a virtual LAN.
