Server 2012 R2 datacenter. I have a key from dreamspark and that key activated server 2012 r2 DC. So far, i have 1 hyper-V running on that server. I want to know how i activate the hyper-V guest server 2012 r2 DC? I also read that if DC has 2 procs, you have to "assign" 2 different keys. How do i do this?
