Storage virtualization is focusing on the provision of a logical, abstracted 
view of physical storage devices without being concerned with where 
(physically located) or how (managed). So, storage virtualization may not 
be directly related to network virtualization, but as you pointed out, some 
of the benefits of storage virtualization may also be applied to network 
virtualization. Migration features are touched in the second bullet as 
a relocation of servers.

Ok. I will add a new bullet.

> In the complex physical networking infrastructure today (e.g., at the core of the network), it is very difficult to add or reserve exclusive physical resources within the physical network for certain application(s) or users. 
> With network virtualization, we should be able to add or reserve physical resources for a single or group of virtual networks, anywhere in the physical network (e.g., at bottleneck points). With this capability, the infrastructure providers can add/reserve (purchase) resources exclusively for certain customers anywhere in the physical network.  This use case is somewhat opposite of "aggregation" and would be worth mentioning in my opinion.

I think that the text above is better fitted for requirement. 
So, I will add it to the requirement section.
