All of my virtual hosts currently run 2008 R2 Enterprise
Unfortunately the SA has expired so I can't upgrade them at present to 2013.
The no-shared-storage migration and replication of HyperV server 2013 is attractive, however, and that edition IS free.
My question is, if I'm still running at least one licenced 2008 R2 Enterprise Server AS A GUEST on the Hyper-V 2013 host, am I still allowed to run 4 servers per physical host?
