VirtualBox Linux Host & Guests

[itpp2012]

It also depends on what the Host has as a nic and how its settings are set,
ea. QoS and LLTP are useless protocols but take resources away, force VM's
to use 1gb FD, another thing is to stick to VBox 3.2, force the GA to use
timesync only. Ea. use IPerf to push settings and boundaries.
