Ok, I am no MS licensing expert, however. Here is my understanding of it.
If you are using a windows vm on a hypervisor other than windows server with the Hyper-V role enabled you need to license per vm. If you are using windows server with Hyper-V enable you can license at the hypervisor/server rather than at the vm level. This does not include Hyper-V server, which only requires licensing of the windows guests. p Peter J.

I've heard that if you use ESXi you can get some sort of license for all Windows images on a host. Not sure of the details of this, though, I've just heard it through the IT grapevine...
