You can download Hyper-V Server 2012 now. This is the same hypervisor, with all the same scale and features as in Windows Server 2012 Hyper-V (Standard and Datacenter edition). The only differences are:
- There are no free virtualisation rights to install Windows Server in guest OS’s on this machine. This means it is good for labs, VDI, Linux hosting, and upgrading older hosts without SA (without upgrading the guest OSs on those hosts).
- There is no GUI. You use PowerShell, SConfig, or remote administration to manage the machine.
- It’s stripped down so it is just a Hyper-V host and nothing else.
