I'm considering some virtualization technologies in our University. And I really don't know which of them to use.
VMWare seem to be the default choice, but with the free version of vSphere 5.1 (atual version) we have the 32GB of system RAM limit. What does not happen in Hyper-V Server 2012.
Since we are an university we have DreamSpark Premium with Hyper-V. So we have the "paid" version of Hyper-V. What is a point in favor of the Microsoft solution.
The main question now is what about Linux guest systems? And BSD ones? We have a lot of Debian systems running and we plain to use some appliances like FreeNAS and pfSense (both FreeBSD based), and we don't know if Hyper-V is a good solution for the unix guys.
Thanks in advance,
EDIT: Just one more thing; we have some Opterons without AMD-V; is this an issue with ESXi or Hyper-V?
