Description of problem: It would be very useful to be able to define virtual networks encapsulated a-la OSP, where not mapped networks to existing physical nics on hosts, could allows vm's to communicate between each other while isolating traffic. This could allow to define set of vm's with backend/frontend networks with Vm's on different hosts .
With basic host deployment done, we can declare that this is ON_QA (though plenty bugfixes remain)
