Whichever entity assigns IP addresses to the host can assign one or many including 1:1 for every VM in that host. This isn't specific to IPv6 or IPv4.
On a general note, devices/appliances etc that want to participate in NV03 will likely want to understand specific tenant information to provide richer services. No matter what the encapsulation format is devices/appliances will need to update if they want to do something interesting with the flow. I have seen several threads where folks seem to have a "let's keep switch-ECMP" view of the DC which I think is narrow.

Does it also mean an IP prefix can be given to a OverlayBoundaryPoint? I guess for IPv6, there shouldn't be any issues, should it? (well I am not an IPv6 expert).
