thats a very arbitrary distinction to me.

we wanted to support the provisioning of private networks between groups of virtual machines, all hosted in the same DC. it would have been nice to simply configure the vlan tags on the hypervisors and let them get tunnelled over the single vlan all the hypervisors are plugged together with on the 5ks. without q-in-q we need to put the vlans on the switches, which is annoying where we are cos we can't arbitrarily allocate tags.
